Parameters:

• params (Object) (defaults to: {}) —
  • computeEnvironmentName — (String)

    The name for your compute environment. It can be up to 128 characters long. It can contain uppercase and lowercase letters, numbers, hyphens (-), and underscores (_).

  • type — (String)

    The type of the compute environment: MANAGED or UNMANAGED. For more information, see Compute Environments in the Batch User Guide.

    Possible values include:
    • "MANAGED"
    • "UNMANAGED"
  • state — (String)

    The state of the compute environment. If the state is ENABLED, then the compute environment accepts jobs from a queue and can scale out automatically based on queues.

    If the state is ENABLED, then the Batch scheduler can attempt to place jobs from an associated job queue on the compute resources within the environment. If the compute environment is managed, then it can scale its instances out or in automatically, based on the job queue demand.

    If the state is DISABLED, then the Batch scheduler doesn't attempt to place jobs within the environment. Jobs in a STARTING or RUNNING state continue to progress normally. Managed compute environments in the DISABLED state don't scale out.

    Note: Compute environments in a DISABLED state may continue to incur billing charges. To prevent additional charges, turn off and then delete the compute environment. For more information, see State in the Batch User Guide.

    When an instance is idle, the instance scales down to the minvCpus value. However, the instance size doesn't change. For example, consider a c5.8xlarge instance with a minvCpus value of 4 and a desiredvCpus value of 36. This instance doesn't scale down to a c5.large instance.

    Possible values include:
    • "ENABLED"
    • "DISABLED"
  • unmanagedvCpus — (Integer)

    The maximum number of vCPUs for an unmanaged compute environment. This parameter is only used for fair share scheduling to reserve vCPU capacity for new share identifiers. If this parameter isn't provided for a fair share job queue, no vCPU capacity is reserved.

    Note: This parameter is only supported when the type parameter is set to UNMANAGED.
  • computeResources — (map)

    Details about the compute resources managed by the compute environment. This parameter is required for managed compute environments. For more information, see Compute Environments in the Batch User Guide.

    • type — required — (String)

      The type of compute environment: EC2, SPOT, FARGATE, or FARGATE_SPOT. For more information, see Compute environments in the Batch User Guide.

      If you choose SPOT, you must also specify an Amazon EC2 Spot Fleet role with the spotIamFleetRole parameter. For more information, see Amazon EC2 spot fleet role in the Batch User Guide.

      Possible values include:
      • "EC2"
      • "SPOT"
      • "FARGATE"
      • "FARGATE_SPOT"
    • allocationStrategy — (String)

      The allocation strategy to use for the compute resource if not enough instances of the best fitting instance type can be allocated. This might be because of availability of the instance type in the Region or Amazon EC2 service limits. For more information, see Allocation strategies in the Batch User Guide.

      Note: This parameter isn't applicable to jobs that are running on Fargate resources. Don't specify it.

      BEST_FIT (default)

      Batch selects an instance type that best fits the needs of the jobs with a preference for the lowest-cost instance type. If additional instances of the selected instance type aren't available, Batch waits for the additional instances to be available. If there aren't enough instances available or the user is reaching Amazon EC2 service limits, additional jobs aren't run until the currently running jobs are completed. This allocation strategy keeps costs lower but can limit scaling. If you're using Spot Fleets with BEST_FIT, the Spot Fleet IAM Role must be specified. Compute resources that use a BEST_FIT allocation strategy don't support infrastructure updates and can't update some parameters. For more information, see Updating compute environments in the Batch User Guide.

      BEST_FIT_PROGRESSIVE

      Batch selects additional instance types that are large enough to meet the requirements of the jobs in the queue. Its preference is for instance types with lower cost vCPUs. If additional instances of the previously selected instance types aren't available, Batch selects new instance types.

      SPOT_CAPACITY_OPTIMIZED

      Batch selects one or more instance types that are large enough to meet the requirements of the jobs in the queue. Its preference is for instance types that are less likely to be interrupted. This allocation strategy is only available for Spot Instance compute resources.

      SPOT_PRICE_CAPACITY_OPTIMIZED

      The price and capacity optimized allocation strategy looks at both price and capacity to select the Spot Instance pools that are the least likely to be interrupted and have the lowest possible price. This allocation strategy is only available for Spot Instance compute resources.

      With BEST_FIT_PROGRESSIVE,SPOT_CAPACITY_OPTIMIZED and SPOT_PRICE_CAPACITY_OPTIMIZED (recommended) strategies using On-Demand or Spot Instances, and the BEST_FIT strategy using Spot Instances, Batch might need to exceed maxvCpus to meet your capacity requirements. In this event, Batch never exceeds maxvCpus by more than a single instance.

      Possible values include:
      • "BEST_FIT"
      • "BEST_FIT_PROGRESSIVE"
      • "SPOT_CAPACITY_OPTIMIZED"
      • "SPOT_PRICE_CAPACITY_OPTIMIZED"
    • minvCpus — (Integer)

      The minimum number of vCPUs that a compute environment should maintain (even if the compute environment is DISABLED).

      Note: This parameter isn't applicable to jobs that are running on Fargate resources. Don't specify it.
    • maxvCpus — required — (Integer)

      The maximum number of vCPUs that a compute environment can support.

      Note: With BEST_FIT_PROGRESSIVE,SPOT_CAPACITY_OPTIMIZED and SPOT_PRICE_CAPACITY_OPTIMIZED (recommended) strategies using On-Demand or Spot Instances, and the BEST_FIT strategy using Spot Instances, Batch might need to exceed maxvCpus to meet your capacity requirements. In this event, Batch never exceeds maxvCpus by more than a single instance.
    • desiredvCpus — (Integer)

      The desired number of vCPUS in the compute environment. Batch modifies this value between the minimum and maximum values based on job queue demand.

      Note: This parameter isn't applicable to jobs that are running on Fargate resources. Don't specify it.
    • instanceTypes — (Array<String>)

      The instances types that can be launched. You can specify instance families to launch any instance type within those families (for example, c5 or p3), or you can specify specific sizes within a family (such as c5.8xlarge). You can also choose optimal to select instance types (from the C4, M4, and R4 instance families) that match the demand of your job queues.

      Note: This parameter isn't applicable to jobs that are running on Fargate resources. Don't specify it.
      Note: When you create a compute environment, the instance types that you select for the compute environment must share the same architecture. For example, you can't mix x86 and ARM instances in the same compute environment.
      Note: Currently, optimal uses instance types from the C4, M4, and R4 instance families. In Regions that don't have instance types from those instance families, instance types from the C5, M5, and R5 instance families are used.
    • imageId — (String)

      The Amazon Machine Image (AMI) ID used for instances launched in the compute environment. This parameter is overridden by the imageIdOverride member of the Ec2Configuration structure.

      Note: This parameter isn't applicable to jobs that are running on Fargate resources. Don't specify it.
      Note: The AMI that you choose for a compute environment must match the architecture of the instance types that you intend to use for that compute environment. For example, if your compute environment uses A1 instance types, the compute resource AMI that you choose must support ARM instances. Amazon ECS vends both x86 and ARM versions of the Amazon ECS-optimized Amazon Linux 2 AMI. For more information, see Amazon ECS-optimized Amazon Linux 2 AMI in the Amazon Elastic Container Service Developer Guide.
    • subnets — required — (Array<String>)

      The VPC subnets where the compute resources are launched. These subnets must be within the same VPC. Fargate compute resources can contain up to 16 subnets. For more information, see VPCs and subnets in the Amazon VPC User Guide.

      Note: Batch on Amazon EC2 and Batch on Amazon EKS support Local Zones. For more information, see Local Zones in the Amazon EC2 User Guide for Linux Instances, Amazon EKS and Amazon Web Services Local Zones in the Amazon EKS User Guide and Amazon ECS clusters in Local Zones, Wavelength Zones, and Amazon Web Services Outposts in the Amazon ECS Developer Guide. Batch on Fargate doesn't currently support Local Zones.
    • securityGroupIds — (Array<String>)

      The Amazon EC2 security groups that are associated with instances launched in the compute environment. One or more security groups must be specified, either in securityGroupIds or using a launch template referenced in launchTemplate. This parameter is required for jobs that are running on Fargate resources and must contain at least one security group. Fargate doesn't support launch templates. If security groups are specified using both securityGroupIds and launchTemplate, the values in securityGroupIds are used.

    • ec2KeyPair — (String)

      The Amazon EC2 key pair that's used for instances launched in the compute environment. You can use this key pair to log in to your instances with SSH.

      Note: This parameter isn't applicable to jobs that are running on Fargate resources. Don't specify it.
    • instanceRole — (String)

      The Amazon ECS instance profile applied to Amazon EC2 instances in a compute environment. This parameter is required for Amazon EC2 instances types. You can specify the short name or full Amazon Resource Name (ARN) of an instance profile. For example, ecsInstanceRole or arn:aws:iam::<aws_account_id>:instance-profile/ecsInstanceRole . For more information, see Amazon ECS instance role in the Batch User Guide.

      Note: This parameter isn't applicable to jobs that are running on Fargate resources. Don't specify it.
    • tags — (map<String>)

      Key-value pair tags to be applied to Amazon EC2 resources that are launched in the compute environment. For Batch, these take the form of "String1": "String2", where String1 is the tag key and String2 is the tag value-for example, { "Name": "Batch Instance - C4OnDemand" }. This is helpful for recognizing your Batch instances in the Amazon EC2 console. Updating these tags requires an infrastructure update to the compute environment. For more information, see Updating compute environments in the Batch User Guide. These tags aren't seen when using the Batch ListTagsForResource API operation.

      Note: This parameter isn't applicable to jobs that are running on Fargate resources. Don't specify it.
    • placementGroup — (String)

      The Amazon EC2 placement group to associate with your compute resources. If you intend to submit multi-node parallel jobs to your compute environment, you should consider creating a cluster placement group and associate it with your compute resources. This keeps your multi-node parallel job on a logical grouping of instances within a single Availability Zone with high network flow potential. For more information, see Placement groups in the Amazon EC2 User Guide for Linux Instances.

      Note: This parameter isn't applicable to jobs that are running on Fargate resources. Don't specify it.
    • bidPercentage — (Integer)

      The maximum percentage that a Spot Instance price can be when compared with the On-Demand price for that instance type before instances are launched. For example, if your maximum percentage is 20%, then the Spot price must be less than 20% of the current On-Demand price for that Amazon EC2 instance. You always pay the lowest (market) price and never more than your maximum percentage. If you leave this field empty, the default value is 100% of the On-Demand price. For most use cases, we recommend leaving this field empty.

      Note: This parameter isn't applicable to jobs that are running on Fargate resources. Don't specify it.
    • spotIamFleetRole — (String)

      The Amazon Resource Name (ARN) of the Amazon EC2 Spot Fleet IAM role applied to a SPOT compute environment. This role is required if the allocation strategy set to BEST_FIT or if the allocation strategy isn't specified. For more information, see Amazon EC2 spot fleet role in the Batch User Guide.

      Note: This parameter isn't applicable to jobs that are running on Fargate resources. Don't specify it.

      To tag your Spot Instances on creation, the Spot Fleet IAM role specified here must use the newer AmazonEC2SpotFleetTaggingRole managed policy. The previously recommended AmazonEC2SpotFleetRole managed policy doesn't have the required permissions to tag Spot Instances. For more information, see Spot instances not tagged on creation in the Batch User Guide.

    • launchTemplate — (map)

      The launch template to use for your compute resources. Any other compute resource parameters that you specify in a CreateComputeEnvironment API operation override the same parameters in the launch template. You must specify either the launch template ID or launch template name in the request, but not both. For more information, see Launch template support in the Batch User Guide.

      Note: This parameter isn't applicable to jobs that are running on Fargate resources. Don't specify it.
      • launchTemplateId — (String)

        The ID of the launch template.

      • launchTemplateName — (String)

        The name of the launch template.

      • version — (String)

        The version number of the launch template, $Latest, or $Default.

        If the value is $Latest, the latest version of the launch template is used. If the value is $Default, the default version of the launch template is used.

        If the AMI ID that's used in a compute environment is from the launch template, the AMI isn't changed when the compute environment is updated. It's only changed if the updateToLatestImageVersion parameter for the compute environment is set to true. During an infrastructure update, if either $Latest or $Default is specified, Batch re-evaluates the launch template version, and it might use a different version of the launch template. This is the case even if the launch template isn't specified in the update. When updating a compute environment, changing the launch template requires an infrastructure update of the compute environment. For more information, see Updating compute environments in the Batch User Guide.

        Default: $Default.

    • ec2Configuration — (Array<map>)

      Provides information that's used to select Amazon Machine Images (AMIs) for Amazon EC2 instances in the compute environment. If Ec2Configuration isn't specified, the default is ECS_AL2.

      One or two values can be provided.

      Note: This parameter isn't applicable to jobs that are running on Fargate resources. Don't specify it.
      • imageType — required — (String)

        The image type to match with the instance type to select an AMI. The supported values are different for ECS and EKS resources.

        ECS

        If the imageIdOverride parameter isn't specified, then a recent Amazon ECS-optimized Amazon Linux 2 AMI (ECS_AL2) is used. If a new image type is specified in an update, but neither an imageId nor a imageIdOverride parameter is specified, then the latest Amazon ECS optimized AMI for that image type that's supported by Batch is used.

        ECS_AL2

        Amazon Linux 2: Default for all non-GPU instance families.

        ECS_AL2_NVIDIA

        Amazon Linux 2 (GPU): Default for all GPU instance families (for example P4 and G4) and can be used for all non Amazon Web Services Graviton-based instance types.

        ECS_AL2023

        Amazon Linux 2023: Batch supports Amazon Linux 2023.

        Note: Amazon Linux 2023 does not support A1 instances.

        ECS_AL1

        Amazon Linux. Amazon Linux has reached the end-of-life of standard support. For more information, see Amazon Linux AMI.

        EKS

        If the imageIdOverride parameter isn't specified, then a recent Amazon EKS-optimized Amazon Linux AMI (EKS_AL2) is used. If a new image type is specified in an update, but neither an imageId nor a imageIdOverride parameter is specified, then the latest Amazon EKS optimized AMI for that image type that Batch supports is used.

        EKS_AL2

        Amazon Linux 2: Default for all non-GPU instance families.

        EKS_AL2_NVIDIA

        Amazon Linux 2 (accelerated): Default for all GPU instance families (for example, P4 and G4) and can be used for all non Amazon Web Services Graviton-based instance types.

      • imageIdOverride — (String)

        The AMI ID used for instances launched in the compute environment that match the image type. This setting overrides the imageId set in the computeResource object.

        Note: The AMI that you choose for a compute environment must match the architecture of the instance types that you intend to use for that compute environment. For example, if your compute environment uses A1 instance types, the compute resource AMI that you choose must support ARM instances. Amazon ECS vends both x86 and ARM versions of the Amazon ECS-optimized Amazon Linux 2 AMI. For more information, see Amazon ECS-optimized Amazon Linux 2 AMI in the Amazon Elastic Container Service Developer Guide.
      • imageKubernetesVersion — (String)

        The Kubernetes version for the compute environment. If you don't specify a value, the latest version that Batch supports is used.

  • serviceRole — (String)

    The full Amazon Resource Name (ARN) of the IAM role that allows Batch to make calls to other Amazon Web Services services on your behalf. For more information, see Batch service IAM role in the Batch User Guide.

    If your account already created the Batch service-linked role, that role is used by default for your compute environment unless you specify a different role here. If the Batch service-linked role doesn't exist in your account, and no role is specified here, the service attempts to create the Batch service-linked role in your account.

    If your specified role has a path other than /, then you must specify either the full role ARN (recommended) or prefix the role name with the path. For example, if a role with the name bar has a path of /foo/, specify /foo/bar as the role name. For more information, see Friendly names and paths in the IAM User Guide.

    Note: Depending on how you created your Batch service role, its ARN might contain the service-role path prefix. When you only specify the name of the service role, Batch assumes that your ARN doesn't use the service-role path prefix. Because of this, we recommend that you specify the full ARN of your service role when you create compute environments.
  • tags — (map<String>)

    The tags that you apply to the compute environment to help you categorize and organize your resources. Each tag consists of a key and an optional value. For more information, see Tagging Amazon Web Services Resources in Amazon Web Services General Reference.

    These tags can be updated or removed using the TagResource and UntagResource API operations. These tags don't propagate to the underlying compute resources.

  • eksConfiguration — (map)

    The details for the Amazon EKS cluster that supports the compute environment.

    • eksClusterArn — required — (String)

      The Amazon Resource Name (ARN) of the Amazon EKS cluster. An example is arn:aws:eks:us-east-1:123456789012:cluster/ClusterForBatch .

    • kubernetesNamespace — required — (String)

      The namespace of the Amazon EKS cluster. Batch manages pods in this namespace. The value can't left empty or null. It must be fewer than 64 characters long, can't be set to default, can't start with "kube-," and must match this regular expression: ^a-z0-9?$. For more information, see Namespaces in the Kubernetes documentation.

  • context — (String)

    Reserved.

Callback (callback):

• function(err, data) { ... }

  Called when a response from the service is returned. If a callback is not supplied, you must call AWS.Request.send() on the returned request object to initiate the request.

  Context (this):

  • (AWS.Response) —

    the response object containing error, data properties, and the original request object.

  Parameters:

  • err (Error) —

    the error object returned from the request. Set to null if the request is successful.

  • data (Object) —

    the de-serialized data returned from the request. Set to null if a request error occurs. The data object has the following properties:

    • computeEnvironmentName — (String)

      The name of the compute environment. It can be up to 128 characters long. It can contain uppercase and lowercase letters, numbers, hyphens (-), and underscores (_).

    • computeEnvironmentArn — (String)

      The Amazon Resource Name (ARN) of the compute environment.

Returns:

• (AWS.Request) —

  a handle to the operation request for subsequent event callback registration.

});

Parameters:

• params (Object) (defaults to: {}) —
  • jobQueueName — (String)

    The name of the job queue. It can be up to 128 letters long. It can contain uppercase and lowercase letters, numbers, hyphens (-), and underscores (_).

  • state — (String)

    The state of the job queue. If the job queue state is ENABLED, it is able to accept jobs. If the job queue state is DISABLED, new jobs can't be added to the queue, but jobs already in the queue can finish.

    Possible values include:
    • "ENABLED"
    • "DISABLED"
  • schedulingPolicyArn — (String)

    The Amazon Resource Name (ARN) of the fair share scheduling policy. If this parameter is specified, the job queue uses a fair share scheduling policy. If this parameter isn't specified, the job queue uses a first in, first out (FIFO) scheduling policy. After a job queue is created, you can replace but can't remove the fair share scheduling policy. The format is aws:Partition:batch:Region:Account:scheduling-policy/Name . An example is aws:aws:batch:us-west-2:123456789012:scheduling-policy/MySchedulingPolicy.

  • priority — (Integer)

    The priority of the job queue. Job queues with a higher priority (or a higher integer value for the priority parameter) are evaluated first when associated with the same compute environment. Priority is determined in descending order. For example, a job queue with a priority value of 10 is given scheduling preference over a job queue with a priority value of 1. All of the compute environments must be either EC2 (EC2 or SPOT) or Fargate (FARGATE or FARGATE_SPOT); EC2 and Fargate compute environments can't be mixed.

  • computeEnvironmentOrder — (Array<map>)

    The set of compute environments mapped to a job queue and their order relative to each other. The job scheduler uses this parameter to determine which compute environment runs a specific job. Compute environments must be in the VALID state before you can associate them with a job queue. You can associate up to three compute environments with a job queue. All of the compute environments must be either EC2 (EC2 or SPOT) or Fargate (FARGATE or FARGATE_SPOT); EC2 and Fargate compute environments can't be mixed.

    Note: All compute environments that are associated with a job queue must share the same architecture. Batch doesn't support mixing compute environment architecture types in a single job queue.
    • order — required — (Integer)

      The order of the compute environment. Compute environments are tried in ascending order. For example, if two compute environments are associated with a job queue, the compute environment with a lower order integer value is tried for job placement first.

    • computeEnvironment — required — (String)

      The Amazon Resource Name (ARN) of the compute environment.

  • tags — (map<String>)

    The tags that you apply to the job queue to help you categorize and organize your resources. Each tag consists of a key and an optional value. For more information, see Tagging your Batch resources in Batch User Guide.

  • jobStateTimeLimitActions — (Array<map>)

    The set of actions that Batch performs on jobs that remain at the head of the job queue in the specified state longer than specified times. Batch will perform each action after maxTimeSeconds has passed.

    • reason — required — (String)

      The reason to log for the action being taken.

    • state — required — (String)

      The state of the job needed to trigger the action. The only supported value is RUNNABLE.

      Possible values include:
      • "RUNNABLE"
    • maxTimeSeconds — required — (Integer)

      The approximate amount of time, in seconds, that must pass with the job in the specified state before the action is taken. The minimum value is 600 (10 minutes) and the maximum value is 86,400 (24 hours).

    • action — required — (String)

      The action to take when a job is at the head of the job queue in the specified state for the specified period of time. The only supported value is CANCEL, which will cancel the job.

      Possible values include:
      • "CANCEL"

Callback (callback):

• function(err, data) { ... }

  Called when a response from the service is returned. If a callback is not supplied, you must call AWS.Request.send() on the returned request object to initiate the request.

  Context (this):

  • (AWS.Response) —

    the response object containing error, data properties, and the original request object.

  Parameters:

  • err (Error) —

    the error object returned from the request. Set to null if the request is successful.

  • data (Object) —

    the de-serialized data returned from the request. Set to null if a request error occurs. The data object has the following properties:

    • jobQueueName — (String)

      The name of the job queue.

    • jobQueueArn — (String)

      The Amazon Resource Name (ARN) of the job queue.

Returns:

• (AWS.Request) —

  a handle to the operation request for subsequent event callback registration.

var params = {
  name: 'STRING_VALUE', /* required */
  fairsharePolicy: {
    computeReservation: 'NUMBER_VALUE',
    shareDecaySeconds: 'NUMBER_VALUE',
    shareDistribution: [
      {
        shareIdentifier: 'STRING_VALUE', /* required */
        weightFactor: 'NUMBER_VALUE'
      },
      /* more items */
    ]
  },
  tags: {
    '<TagKey>': 'STRING_VALUE',
    /* '<TagKey>': ... */
  }
};
batch.createSchedulingPolicy(params, function(err, data) {
  if (err) console.log(err, err.stack); // an error occurred
  else     console.log(data);           // successful response
});

Parameters:

• params (Object) (defaults to: {}) —
  • name — (String)

    The name of the scheduling policy. It can be up to 128 letters long. It can contain uppercase and lowercase letters, numbers, hyphens (-), and underscores (_).

  • fairsharePolicy — (map)

    The fair share policy of the scheduling policy.

    • shareDecaySeconds — (Integer)

      The amount of time (in seconds) to use to calculate a fair share percentage for each fair share identifier in use. A value of zero (0) indicates that only current usage is measured. The decay allows for more recently run jobs to have more weight than jobs that ran earlier. The maximum supported value is 604800 (1 week).

    • computeReservation — (Integer)

      A value used to reserve some of the available maximum vCPU for fair share identifiers that aren't already used.

      The reserved ratio is (computeReservation/100)^ActiveFairShares where ActiveFairShares is the number of active fair share identifiers.

      For example, a computeReservation value of 50 indicates that Batch reserves 50% of the maximum available vCPU if there's only one fair share identifier. It reserves 25% if there are two fair share identifiers. It reserves 12.5% if there are three fair share identifiers. A computeReservation value of 25 indicates that Batch should reserve 25% of the maximum available vCPU if there's only one fair share identifier, 6.25% if there are two fair share identifiers, and 1.56% if there are three fair share identifiers.

      The minimum value is 0 and the maximum value is 99.

    • shareDistribution — (Array<map>)

      An array of SharedIdentifier objects that contain the weights for the fair share identifiers for the fair share policy. Fair share identifiers that aren't included have a default weight of 1.0.

      • shareIdentifier — required — (String)

        A fair share identifier or fair share identifier prefix. If the string ends with an asterisk (), this entry specifies the weight factor to use for fair share identifiers that start with that prefix. The list of fair share identifiers in a fair share policy can't overlap. For example, you can't have one that specifies a shareIdentifier of UserA* and another that specifies a shareIdentifier of UserA-1.

        There can be no more than 500 fair share identifiers active in a job queue.

        The string is limited to 255 alphanumeric characters, and can be followed by an asterisk ().

      • weightFactor — (Float)

        The weight factor for the fair share identifier. The default value is 1.0. A lower value has a higher priority for compute resources. For example, jobs that use a share identifier with a weight factor of 0.125 (1/8) get 8 times the compute resources of jobs that use a share identifier with a weight factor of 1.

        The smallest supported value is 0.0001, and the largest supported value is 999.9999.

  • tags — (map<String>)

    The tags that you apply to the scheduling policy to help you categorize and organize your resources. Each tag consists of a key and an optional value. For more information, see Tagging Amazon Web Services Resources in Amazon Web Services General Reference.

    These tags can be updated or removed using the TagResource and UntagResource API operations.

Parameters:

• params (Object) (defaults to: {}) —
  • computeEnvironments — (Array<String>)

    A list of up to 100 compute environment names or full Amazon Resource Name (ARN) entries.

  • maxResults — (Integer)

    The maximum number of cluster results returned by DescribeComputeEnvironments in paginated output. When this parameter is used, DescribeComputeEnvironments only returns maxResults results in a single page along with a nextToken response element. The remaining results of the initial request can be seen by sending another DescribeComputeEnvironments request with the returned nextToken value. This value can be between 1 and 100. If this parameter isn't used, then DescribeComputeEnvironments returns up to 100 results and a nextToken value if applicable.

  • nextToken — (String)

    The nextToken value returned from a previous paginated DescribeComputeEnvironments request where maxResults was used and the results exceeded the value of that parameter. Pagination continues from the end of the previous results that returned the nextToken value. This value is null when there are no more results to return.

    Note: Treat this token as an opaque identifier that's only used to retrieve the next items in a list and not for other programmatic purposes.

Callback (callback):

• function(err, data) { ... }

  Called when a response from the service is returned. If a callback is not supplied, you must call AWS.Request.send() on the returned request object to initiate the request.

  Context (this):

  • (AWS.Response) —

    the response object containing error, data properties, and the original request object.

  Parameters:

  • err (Error) —

    the error object returned from the request. Set to null if the request is successful.

  • data (Object) —

    the de-serialized data returned from the request. Set to null if a request error occurs. The data object has the following properties:

    • computeEnvironments — (Array<map>)

      The list of compute environments.

      • computeEnvironmentName — required — (String)

        The name of the compute environment. It can be up to 128 characters long. It can contain uppercase and lowercase letters, numbers, hyphens (-), and underscores (_).

      • computeEnvironmentArn — required — (String)

        The Amazon Resource Name (ARN) of the compute environment.

      • unmanagedvCpus — (Integer)

        The maximum number of VCPUs expected to be used for an unmanaged compute environment.

      • ecsClusterArn — (String)

        The Amazon Resource Name (ARN) of the underlying Amazon ECS cluster that the compute environment uses.

      • tags — (map<String>)

        The tags applied to the compute environment.

      • type — (String)

        The type of the compute environment: MANAGED or UNMANAGED. For more information, see Compute environments in the Batch User Guide.

        Possible values include:
        • "MANAGED"
        • "UNMANAGED"
      • state — (String)

        The state of the compute environment. The valid values are ENABLED or DISABLED.

        If the state is ENABLED, then the Batch scheduler can attempt to place jobs from an associated job queue on the compute resources within the environment. If the compute environment is managed, then it can scale its instances out or in automatically based on the job queue demand.

        If the state is DISABLED, then the Batch scheduler doesn't attempt to place jobs within the environment. Jobs in a STARTING or RUNNING state continue to progress normally. Managed compute environments in the DISABLED state don't scale out.

        Note: Compute environments in a DISABLED state may continue to incur billing charges. To prevent additional charges, turn off and then delete the compute environment. For more information, see State in the Batch User Guide.

        When an instance is idle, the instance scales down to the minvCpus value. However, the instance size doesn't change. For example, consider a c5.8xlarge instance with a minvCpus value of 4 and a desiredvCpus value of 36. This instance doesn't scale down to a c5.large instance.

        Possible values include:
        • "ENABLED"
        • "DISABLED"
      • status — (String)

        The current status of the compute environment (for example, CREATING or VALID).

        Possible values include:
        • "CREATING"
        • "UPDATING"
        • "DELETING"
        • "DELETED"
        • "VALID"
        • "INVALID"
      • statusReason — (String)

        A short, human-readable string to provide additional details for the current status of the compute environment.

      • computeResources — (map)

        The compute resources defined for the compute environment. For more information, see Compute environments in the Batch User Guide.

        • type — required — (String)

          The type of compute environment: EC2, SPOT, FARGATE, or FARGATE_SPOT. For more information, see Compute environments in the Batch User Guide.

          If you choose SPOT, you must also specify an Amazon EC2 Spot Fleet role with the spotIamFleetRole parameter. For more information, see Amazon EC2 spot fleet role in the Batch User Guide.

          Possible values include:
          • "EC2"
          • "SPOT"
          • "FARGATE"
          • "FARGATE_SPOT"
        • allocationStrategy — (String)

          The allocation strategy to use for the compute resource if not enough instances of the best fitting instance type can be allocated. This might be because of availability of the instance type in the Region or Amazon EC2 service limits. For more information, see Allocation strategies in the Batch User Guide.

          Note: This parameter isn't applicable to jobs that are running on Fargate resources. Don't specify it.

          BEST_FIT (default)

          Batch selects an instance type that best fits the needs of the jobs with a preference for the lowest-cost instance type. If additional instances of the selected instance type aren't available, Batch waits for the additional instances to be available. If there aren't enough instances available or the user is reaching Amazon EC2 service limits, additional jobs aren't run until the currently running jobs are completed. This allocation strategy keeps costs lower but can limit scaling. If you're using Spot Fleets with BEST_FIT, the Spot Fleet IAM Role must be specified. Compute resources that use a BEST_FIT allocation strategy don't support infrastructure updates and can't update some parameters. For more information, see Updating compute environments in the Batch User Guide.

          BEST_FIT_PROGRESSIVE

          Batch selects additional instance types that are large enough to meet the requirements of the jobs in the queue. Its preference is for instance types with lower cost vCPUs. If additional instances of the previously selected instance types aren't available, Batch selects new instance types.

          SPOT_CAPACITY_OPTIMIZED

          Batch selects one or more instance types that are large enough to meet the requirements of the jobs in the queue. Its preference is for instance types that are less likely to be interrupted. This allocation strategy is only available for Spot Instance compute resources.

          SPOT_PRICE_CAPACITY_OPTIMIZED

          The price and capacity optimized allocation strategy looks at both price and capacity to select the Spot Instance pools that are the least likely to be interrupted and have the lowest possible price. This allocation strategy is only available for Spot Instance compute resources.

          With BEST_FIT_PROGRESSIVE,SPOT_CAPACITY_OPTIMIZED and SPOT_PRICE_CAPACITY_OPTIMIZED (recommended) strategies using On-Demand or Spot Instances, and the BEST_FIT strategy using Spot Instances, Batch might need to exceed maxvCpus to meet your capacity requirements. In this event, Batch never exceeds maxvCpus by more than a single instance.

          Possible values include:
          • "BEST_FIT"
          • "BEST_FIT_PROGRESSIVE"
          • "SPOT_CAPACITY_OPTIMIZED"
          • "SPOT_PRICE_CAPACITY_OPTIMIZED"
        • minvCpus — (Integer)

          The minimum number of vCPUs that a compute environment should maintain (even if the compute environment is DISABLED).

          Note: This parameter isn't applicable to jobs that are running on Fargate resources. Don't specify it.
        • maxvCpus — required — (Integer)

          The maximum number of vCPUs that a compute environment can support.

          Note: With BEST_FIT_PROGRESSIVE,SPOT_CAPACITY_OPTIMIZED and SPOT_PRICE_CAPACITY_OPTIMIZED (recommended) strategies using On-Demand or Spot Instances, and the BEST_FIT strategy using Spot Instances, Batch might need to exceed maxvCpus to meet your capacity requirements. In this event, Batch never exceeds maxvCpus by more than a single instance.
        • desiredvCpus — (Integer)

          The desired number of vCPUS in the compute environment. Batch modifies this value between the minimum and maximum values based on job queue demand.

          Note: This parameter isn't applicable to jobs that are running on Fargate resources. Don't specify it.
        • instanceTypes — (Array<String>)

          The instances types that can be launched. You can specify instance families to launch any instance type within those families (for example, c5 or p3), or you can specify specific sizes within a family (such as c5.8xlarge). You can also choose optimal to select instance types (from the C4, M4, and R4 instance families) that match the demand of your job queues.

          Note: This parameter isn't applicable to jobs that are running on Fargate resources. Don't specify it.
          Note: When you create a compute environment, the instance types that you select for the compute environment must share the same architecture. For example, you can't mix x86 and ARM instances in the same compute environment.
          Note: Currently, optimal uses instance types from the C4, M4, and R4 instance families. In Regions that don't have instance types from those instance families, instance types from the C5, M5, and R5 instance families are used.
        • imageId — (String)

          The Amazon Machine Image (AMI) ID used for instances launched in the compute environment. This parameter is overridden by the imageIdOverride member of the Ec2Configuration structure.

          Note: This parameter isn't applicable to jobs that are running on Fargate resources. Don't specify it.
          Note: The AMI that you choose for a compute environment must match the architecture of the instance types that you intend to use for that compute environment. For example, if your compute environment uses A1 instance types, the compute resource AMI that you choose must support ARM instances. Amazon ECS vends both x86 and ARM versions of the Amazon ECS-optimized Amazon Linux 2 AMI. For more information, see Amazon ECS-optimized Amazon Linux 2 AMI in the Amazon Elastic Container Service Developer Guide.
        • subnets — required — (Array<String>)

          The VPC subnets where the compute resources are launched. These subnets must be within the same VPC. Fargate compute resources can contain up to 16 subnets. For more information, see VPCs and subnets in the Amazon VPC User Guide.

          Note: Batch on Amazon EC2 and Batch on Amazon EKS support Local Zones. For more information, see Local Zones in the Amazon EC2 User Guide for Linux Instances, Amazon EKS and Amazon Web Services Local Zones in the Amazon EKS User Guide and Amazon ECS clusters in Local Zones, Wavelength Zones, and Amazon Web Services Outposts in the Amazon ECS Developer Guide. Batch on Fargate doesn't currently support Local Zones.
        • securityGroupIds — (Array<String>)

          The Amazon EC2 security groups that are associated with instances launched in the compute environment. One or more security groups must be specified, either in securityGroupIds or using a launch template referenced in launchTemplate. This parameter is required for jobs that are running on Fargate resources and must contain at least one security group. Fargate doesn't support launch templates. If security groups are specified using both securityGroupIds and launchTemplate, the values in securityGroupIds are used.

        • ec2KeyPair — (String)

          The Amazon EC2 key pair that's used for instances launched in the compute environment. You can use this key pair to log in to your instances with SSH.

          Note: This parameter isn't applicable to jobs that are running on Fargate resources. Don't specify it.
        • instanceRole — (String)

          The Amazon ECS instance profile applied to Amazon EC2 instances in a compute environment. This parameter is required for Amazon EC2 instances types. You can specify the short name or full Amazon Resource Name (ARN) of an instance profile. For example, ecsInstanceRole or arn:aws:iam::<aws_account_id>:instance-profile/ecsInstanceRole . For more information, see Amazon ECS instance role in the Batch User Guide.

          Note: This parameter isn't applicable to jobs that are running on Fargate resources. Don't specify it.
        • tags — (map<String>)

          Key-value pair tags to be applied to Amazon EC2 resources that are launched in the compute environment. For Batch, these take the form of "String1": "String2", where String1 is the tag key and String2 is the tag value-for example, { "Name": "Batch Instance - C4OnDemand" }. This is helpful for recognizing your Batch instances in the Amazon EC2 console. Updating these tags requires an infrastructure update to the compute environment. For more information, see Updating compute environments in the Batch User Guide. These tags aren't seen when using the Batch ListTagsForResource API operation.

          Note: This parameter isn't applicable to jobs that are running on Fargate resources. Don't specify it.
        • placementGroup — (String)

          The Amazon EC2 placement group to associate with your compute resources. If you intend to submit multi-node parallel jobs to your compute environment, you should consider creating a cluster placement group and associate it with your compute resources. This keeps your multi-node parallel job on a logical grouping of instances within a single Availability Zone with high network flow potential. For more information, see Placement groups in the Amazon EC2 User Guide for Linux Instances.

          Note: This parameter isn't applicable to jobs that are running on Fargate resources. Don't specify it.
        • bidPercentage — (Integer)

          The maximum percentage that a Spot Instance price can be when compared with the On-Demand price for that instance type before instances are launched. For example, if your maximum percentage is 20%, then the Spot price must be less than 20% of the current On-Demand price for that Amazon EC2 instance. You always pay the lowest (market) price and never more than your maximum percentage. If you leave this field empty, the default value is 100% of the On-Demand price. For most use cases, we recommend leaving this field empty.

          Note: This parameter isn't applicable to jobs that are running on Fargate resources. Don't specify it.
        • spotIamFleetRole — (String)

          The Amazon Resource Name (ARN) of the Amazon EC2 Spot Fleet IAM role applied to a SPOT compute environment. This role is required if the allocation strategy set to BEST_FIT or if the allocation strategy isn't specified. For more information, see Amazon EC2 spot fleet role in the Batch User Guide.

          Note: This parameter isn't applicable to jobs that are running on Fargate resources. Don't specify it.

          To tag your Spot Instances on creation, the Spot Fleet IAM role specified here must use the newer AmazonEC2SpotFleetTaggingRole managed policy. The previously recommended AmazonEC2SpotFleetRole managed policy doesn't have the required permissions to tag Spot Instances. For more information, see Spot instances not tagged on creation in the Batch User Guide.

        • launchTemplate — (map)

          The launch template to use for your compute resources. Any other compute resource parameters that you specify in a CreateComputeEnvironment API operation override the same parameters in the launch template. You must specify either the launch template ID or launch template name in the request, but not both. For more information, see Launch template support in the Batch User Guide.

          Note: This parameter isn't applicable to jobs that are running on Fargate resources. Don't specify it.
          • launchTemplateId — (String)

            The ID of the launch template.

          • launchTemplateName — (String)

            The name of the launch template.

          • version — (String)

            The version number of the launch template, $Latest, or $Default.

            If the value is $Latest, the latest version of the launch template is used. If the value is $Default, the default version of the launch template is used.

            If the AMI ID that's used in a compute environment is from the launch template, the AMI isn't changed when the compute environment is updated. It's only changed if the updateToLatestImageVersion parameter for the compute environment is set to true. During an infrastructure update, if either $Latest or $Default is specified, Batch re-evaluates the launch template version, and it might use a different version of the launch template. This is the case even if the launch template isn't specified in the update. When updating a compute environment, changing the launch template requires an infrastructure update of the compute environment. For more information, see Updating compute environments in the Batch User Guide.

            Default: $Default.

        • ec2Configuration — (Array<map>)

          Provides information that's used to select Amazon Machine Images (AMIs) for Amazon EC2 instances in the compute environment. If Ec2Configuration isn't specified, the default is ECS_AL2.

          One or two values can be provided.

          Note: This parameter isn't applicable to jobs that are running on Fargate resources. Don't specify it.
          • imageType — required — (String)

            The image type to match with the instance type to select an AMI. The supported values are different for ECS and EKS resources.

            ECS

            If the imageIdOverride parameter isn't specified, then a recent Amazon ECS-optimized Amazon Linux 2 AMI (ECS_AL2) is used. If a new image type is specified in an update, but neither an imageId nor a imageIdOverride parameter is specified, then the latest Amazon ECS optimized AMI for that image type that's supported by Batch is used.

            ECS_AL2

            Amazon Linux 2: Default for all non-GPU instance families.

            ECS_AL2_NVIDIA

            Amazon Linux 2 (GPU): Default for all GPU instance families (for example P4 and G4) and can be used for all non Amazon Web Services Graviton-based instance types.

            ECS_AL2023

            Amazon Linux 2023: Batch supports Amazon Linux 2023.

            Note: Amazon Linux 2023 does not support A1 instances.

            ECS_AL1

            Amazon Linux. Amazon Linux has reached the end-of-life of standard support. For more information, see Amazon Linux AMI.

            EKS

            If the imageIdOverride parameter isn't specified, then a recent Amazon EKS-optimized Amazon Linux AMI (EKS_AL2) is used. If a new image type is specified in an update, but neither an imageId nor a imageIdOverride parameter is specified, then the latest Amazon EKS optimized AMI for that image type that Batch supports is used.

            EKS_AL2

            Amazon Linux 2: Default for all non-GPU instance families.

            EKS_AL2_NVIDIA

            Amazon Linux 2 (accelerated): Default for all GPU instance families (for example, P4 and G4) and can be used for all non Amazon Web Services Graviton-based instance types.

          • imageIdOverride — (String)

            The AMI ID used for instances launched in the compute environment that match the image type. This setting overrides the imageId set in the computeResource object.

            Note: The AMI that you choose for a compute environment must match the architecture of the instance types that you intend to use for that compute environment. For example, if your compute environment uses A1 instance types, the compute resource AMI that you choose must support ARM instances. Amazon ECS vends both x86 and ARM versions of the Amazon ECS-optimized Amazon Linux 2 AMI. For more information, see Amazon ECS-optimized Amazon Linux 2 AMI in the Amazon Elastic Container Service Developer Guide.
          • imageKubernetesVersion — (String)

Parameters:

• params (Object) (defaults to: {}) —
  • jobDefinitions — (Array<String>)

    A list of up to 100 job definitions. Each entry in the list can either be an ARN in the format arn:aws:batch:${Region}:${Account}:job-definition/${JobDefinitionName}:${Revision} or a short version using the form ${JobDefinitionName}:${Revision}. This parameter can't be used with other parameters.

  • maxResults — (Integer)

    The maximum number of results returned by DescribeJobDefinitions in paginated output. When this parameter is used, DescribeJobDefinitions only returns maxResults results in a single page and a nextToken response element. The remaining results of the initial request can be seen by sending another DescribeJobDefinitions request with the returned nextToken value. This value can be between 1 and 100. If this parameter isn't used, then DescribeJobDefinitions returns up to 100 results and a nextToken value if applicable.

  • jobDefinitionName — (String)

    The name of the job definition to describe.

  • status — (String)

    The status used to filter job definitions.

  • nextToken — (String)

    The nextToken value returned from a previous paginated DescribeJobDefinitions request where maxResults was used and the results exceeded the value of that parameter. Pagination continues from the end of the previous results that returned the nextToken value. This value is null when there are no more results to return.

    Note: Treat this token as an opaque identifier that's only used to retrieve the next items in a list and not for other programmatic purposes.

Callback (callback):

• function(err, data) { ... }

  Called when a response from the service is returned. If a callback is not supplied, you must call AWS.Request.send() on the returned request object to initiate the request.

  Context (this):

  • (AWS.Response) —

    the response object containing error, data properties, and the original request object.

  Parameters:

  • err (Error) —

      • schedulingPriority — (Integer)

        The scheduling priority of the job definition. This only affects jobs in job queues with a fair share policy. Jobs with a higher scheduling priority are scheduled before jobs with a lower scheduling priority.

      • parameters — (map<String>)

        Default parameters or parameter substitution placeholders that are set in the job definition. Parameters are specified as a key-value pair mapping. Parameters in a SubmitJob request override any corresponding parameter defaults from the job definition. For more information about specifying parameters, see Job definition parameters in the Batch User Guide.

      • retryStrategy — (map)

        The retry strategy to use for failed jobs that are submitted with this job definition.

        • attempts — (Integer)

          The number of times to move a job to the RUNNABLE status. You can specify between 1 and 10 attempts. If the value of attempts is greater than one, the job is retried on failure the same number of attempts as the value.

        • evaluateOnExit — (Array<map>)

          Array of up to 5 objects that specify the conditions where jobs are retried or failed. If this parameter is specified, then the attempts parameter must also be specified. If none of the listed conditions match, then the job is retried.

          • onStatusReason — (String)

            Contains a glob pattern to match against the StatusReason returned for a job. The pattern can contain up to 512 characters. It can contain letters, numbers, periods (.), colons (:), and white spaces (including spaces or tabs). It can optionally end with an asterisk (*) so that only the start of the string needs to be an exact match.

          • onReason — (String)

            Contains a glob pattern to match against the Reason returned for a job. The pattern can contain up to 512 characters. It can contain letters, numbers, periods (.), colons (:), and white space (including spaces and tabs). It can optionally end with an asterisk (*) so that only the start of the string needs to be an exact match.

          • onExitCode — (String)

            Contains a glob pattern to match against the decimal representation of the ExitCode returned for a job. The pattern can be up to 512 characters long. It can contain only numbers, and can end with an asterisk (*) so that only the start of the string needs to be an exact match.

            The string can contain up to 512 characters.

        • image — (String)

          Required. The image used to start a container. This string is passed directly to the Docker daemon. Images in the Docker Hub registry are available by default. Other repositories are specified with repository-url/image:tag . It can be 255 characters long. It can contain uppercase and lowercase letters, numbers, hyphens (-), underscores (_), colons (:), periods (.), forward slashes (/), and number signs (#). This parameter maps to Image in the Create a container section of the Docker Remote API and the IMAGE parameter of docker run.

          Note: Docker image architecture must match the processor architecture of the compute resources that they're scheduled on. For example, ARM-based Docker images can only run on ARM-based compute resources.

          • Images in Amazon ECR Public repositories use the full registry/repository[:tag] or registry/repository[@digest] naming conventions. For example, public.ecr.aws/registry_alias/my-web-app:latest .

          • Images in Amazon ECR repositories use the full registry and repository URI (for example, 123456789012.dkr.ecr.<region-name>.amazonaws.com/<repository-name>).

          • Images in official repositories on Docker Hub use a single name (for example, ubuntu or mongo).

          • Images in other repositories on Docker Hub are qualified with an organization name (for example, amazon/amazon-ecs-agent).

          • Images in other online repositories are qualified further by a domain name (for example, quay.io/assemblyline/ubuntu).

        • vcpus — (Integer)

          This parameter is deprecated, use resourceRequirements to specify the vCPU requirements for the job definition. It's not supported for jobs running on Fargate resources. For jobs running on Amazon EC2 resources, it specifies the number of vCPUs reserved for the job.

          Each vCPU is equivalent to 1,024 CPU shares. This parameter maps to CpuShares in the Create a container section of the Docker Remote API and the --cpu-shares option to docker run. The number of vCPUs must be specified but can be specified in several places. You must specify it at least once for each node.

        • memory — (Integer)

          This parameter is deprecated, use resourceRequirements to specify the memory requirements for the job definition. It's not supported for jobs running on Fargate resources. For jobs that run on Amazon EC2 resources, it specifies the memory hard limit (in MiB) for a container. If your container attempts to exceed the specified number, it's terminated. You must specify at least 4 MiB of memory for a job using this parameter. The memory hard limit can be specified in several places. It must be specified for each node at least once.

        • command — (Array<String>)

          The command that's passed to the container. This parameter maps to Cmd in the Create a container section of the Docker Remote API and the COMMAND parameter to docker run. For more information, see https://docs.docker.com/engine/reference/builder/#cmd.

        • jobRoleArn — (String)

          The Amazon Resource Name (ARN) of the IAM role that the container can assume for Amazon Web Services permissions. For more information, see IAM roles for tasks in the Amazon Elastic Container Service Developer Guide.

        • executionRoleArn — (String)

          The Amazon Resource Name (ARN) of the execution role that Batch can assume. For jobs that run on Fargate resources, you must provide an execution role. For more information, see Batch execution IAM role in the Batch User Guide.

        • volumes — (Array<map>)

          A list of data volumes used in a job.

          • host — (map)

            The contents of the host parameter determine whether your data volume persists on the host container instance and where it's stored. If the host parameter is empty, then the Docker daemon assigns a host path for your data volume. However, the data isn't guaranteed to persist after the containers that are associated with it stop running.

            Note: This parameter isn't applicable to jobs that are running on Fargate resources and shouldn't be provided.
            • sourcePath — (String)

              The path on the host container instance that's presented to the container. If this parameter is empty, then the Docker daemon has assigned a host path for you. If this parameter contains a file location, then the data volume persists at the specified location on the host container instance until you delete it manually. If the source path location doesn't exist on the host container instance, the Docker daemon creates it. If the location does exist, the contents of the source path folder are exported.

              Note: This parameter isn't applicable to jobs that run on Fargate resources. Don't provide this for these jobs.
          • name — (String)

            The name of the volume. It can be up to 255 characters long. It can contain uppercase and lowercase letters, numbers, hyphens (-), and underscores (_). This name is referenced in the sourceVolume parameter of container definition mountPoints.

          • efsVolumeConfiguration — (map)

            This parameter is specified when you're using an Amazon Elastic File System file system for job storage. Jobs that are running on Fargate resources must specify a platformVersion of at least 1.4.0.

            • fileSystemId — required — (String)

              The Amazon EFS file system ID to use.

            • rootDirectory — (String)

              The directory within the Amazon EFS file system to mount as the root directory inside the host. If this parameter is omitted, the root of the Amazon EFS volume is used instead. Specifying / has the same effect as omitting this parameter. The maximum length is 4,096 characters.

              If an EFS access point is specified in the authorizationConfig, the root directory parameter must either be omitted or set to /, which enforces the path set on the Amazon EFS access point.

            • transitEncryption — (String)

              Determines whether to enable encryption for Amazon EFS data in transit between the Amazon ECS host and the Amazon EFS server. Transit encryption must be enabled if Amazon EFS IAM authorization is used. If this parameter is omitted, the default value of DISABLED is used. For more information, see Encrypting data in transit in the Amazon Elastic File System User Guide.

              Possible values include:
              • "ENABLED"
              • "DISABLED"
            • transitEncryptionPort — (Integer)

              The port to use when sending encrypted data between the Amazon ECS host and the Amazon EFS server.

            type="MEMORY"

            The memory hard limit (in MiB) present to the container. This parameter is supported for jobs that are running on Amazon EC2 resources. If your container attempts to exceed the memory specified, the container is terminated. This parameter maps to Memory in the Create a container section of the Docker Remote API and the --memory option to docker run. You must specify at least 4 MiB of memory for a job. This is required but can be specified in several places for multi-node parallel (MNP) jobs. It must be specified for each node at least once. This parameter maps to Memory in the Create a container section of the Docker Remote API and the --memory option to docker run.

            Note: If you're trying to maximize your resource utilization by providing your jobs as much memory as possible for a particular instance type, see Memory management in the Batch User Guide.

            For jobs that are running on Fargate resources, then value is the hard limit (in MiB), and must match one of the supported values and the VCPU values must be one of the values supported for that memory value.

          • initProcessEnabled — (Boolean)

            If true, run an init process inside the container that forwards signals and reaps processes. This parameter maps to the --init option to docker run. This parameter requires version 1.25 of the Docker Remote API or greater on your container instance. To check the Docker Remote API version on your container instance, log in to your container instance and run the following command: sudo docker version | grep "Server API version"

          • sharedMemorySize — (Integer)

            The value for the size (in MiB) of the /dev/shm volume. This parameter maps to the --shm-size option to docker run.

            Note: This parameter isn't applicable to jobs that are running on Fargate resources. Don't provide it for these jobs.
          • tmpfs — (Array<map>)

            The container path, mount options, and size (in MiB) of the tmpfs mount. This parameter maps to the --tmpfs option to docker run.

            Note: This parameter isn't applicable to jobs that are running on Fargate resources. Don't provide this parameter for this resource type.
            • containerPath — required — (String)

              The absolute file path in the container where the tmpfs volume is mounted.

            • size — required — (Integer)

          • maxSwap — (Integer)

            The total amount of swap memory (in MiB) a container can use. This parameter is translated to the --memory-swap option to docker run where the value is the sum of the container memory plus the maxSwap value. For more information, see --memory-swap details in the Docker documentation.

            If a maxSwap value of 0 is specified, the container doesn't use swap. Accepted values are 0 or any positive integer. If the maxSwap parameter is omitted, the container doesn't use the swap configuration for the container instance that it's running on. A maxSwap value must be set for the swappiness parameter to be used.

            Note: This parameter isn't applicable to jobs that are running on Fargate resources. Don't provide it for these jobs.
          • swappiness — (Integer)

            You can use this parameter to tune a container's memory swappiness behavior. A swappiness value of 0 causes swapping to not occur unless absolutely necessary. A swappiness value of 100 causes pages to be swapped aggressively. Valid values are whole numbers between 0 and 100. If the swappiness parameter isn't specified, a default value of 60 is used. If a value isn't specified for maxSwap, then this parameter is ignored. If maxSwap is set to 0, the container doesn't use swap. This parameter maps to the --memory-swappiness option to docker run.

            Consider the following when you use a per-container swap configuration.

            • Swap space must be enabled and allocated on the container instance for the containers to use.

              Note: By default, the Amazon ECS optimized AMIs don't have swap enabled. You must enable swap on the instance to use this feature. For more information, see Instance store swap volumes in the Amazon EC2 User Guide for Linux Instances or How do I allocate memory to work as swap space in an Amazon EC2 instance by using a swap file?

            • The swap space parameters are only supported for job definitions using EC2 resources.

            • If the maxSwap and swappiness parameters are omitted from a job definition, each container has a default swappiness value of 60. Moreover, the total swap usage is limited to two times the memory reservation of the container.

            Note: This parameter isn't applicable to jobs that are running on Fargate resources. Don't provide it for these jobs.
        • logConfiguration — (map)

          The log configuration specification for the container.

          This parameter maps to LogConfig in the Create a container section of the Docker Remote API and the --log-driver option to docker run. By default, containers use the same logging driver that the Docker daemon uses. However the container might use a different logging driver than the Docker daemon by specifying a log driver with this parameter in the container definition. To use a different logging driver for a container, the log system must be configured properly on the container instance (or on a different log server for remote logging options). For more information on the options for different supported log drivers, see Configure logging drivers in the Docker documentation.

          Note: Batch currently supports a subset of the logging drivers available to the Docker daemon (shown in the LogConfiguration data type).

          This parameter requires version 1.18 of the Docker Remote API or greater on your container instance. To check the Docker Remote API version on your container instance, log in to your container instance and run the following command: sudo docker version | grep "Server API version"

          Note: The Amazon ECS container agent running on a container instance must register the logging drivers available on that instance with the ECS_AVAILABLE_LOGGING_DRIVERS environment variable before containers placed on that instance can use these log configuration options. For more information, see Amazon ECS container agent configuration in the Amazon Elastic Container Service Developer Guide.
          • logDriver — required — (String)

            The log driver to use for the container. The valid values that are listed for this parameter are log drivers that the Amazon ECS container agent can communicate with by default.

            The supported log drivers are awslogs, fluentd, gelf, json-file, journald, logentries, syslog, and splunk.

            Note: Jobs that are running on Fargate resources are restricted to the awslogs and splunk log drivers.

            awslogs

            Specifies the Amazon CloudWatch Logs logging driver. For more information, see Using the awslogs log driver in the Batch User Guide and Amazon CloudWatch Logs logging driver in the Docker documentation.

            fluentd

            Specifies the Fluentd logging driver. For more information including usage and options, see Fluentd logging driver in the Docker documentation.

            gelf

            syslog

            Specifies the syslog logging driver. For more information including usage and options, see Syslog logging driver in the Docker documentation.

            Note: If you have a custom driver that's not listed earlier that you want to work with the Amazon ECS container agent, you can fork the Amazon ECS container agent project that's available on GitHub and customize it to work with that driver. We encourage you to submit pull requests for changes that you want to have included. However, Amazon Web Services doesn't currently support running modified copies of this software.

            This parameter requires version 1.18 of the Docker Remote API or greater on your container instance. To check the Docker Remote API version on your container instance, log in to your container instance and run the following command: sudo docker version | grep "Server API version"

          • platformVersion — (String)

            The Fargate platform version where the jobs are running. A platform version is specified only for jobs that are running on Fargate resources. If one isn't specified, the LATEST platform version is used by default. This uses a recent, approved version of the Fargate platform for compute resources. For more information, see Fargate platform versions in the Amazon Elastic Container Service Developer Guide.

        • ephemeralStorage — (map)

          The amount of ephemeral storage to allocate for the task. This parameter is used to expand the total amount of ephemeral storage available, beyond the default amount, for tasks hosted on Fargate.

          • sizeInGiB — required — (Integer)

            The total amount, in GiB, of ephemeral storage to set for the task. The minimum supported value is 21 GiB and the maximum supported value is 200 GiB.

        • runtimePlatform — (map)

          An object that represents the compute environment architecture for Batch jobs on Fargate.

          • operatingSystemFamily — (String)

            The operating system for the compute environment. Valid values are: LINUX (default), WINDOWS_SERVER_2019_CORE, WINDOWS_SERVER_2019_FULL, WINDOWS_SERVER_2022_CORE, and WINDOWS_SERVER_2022_FULL.

            Note: The following parameters can’t be set for Windows containers: linuxParameters, privileged, user, ulimits, readonlyRootFilesystem, and efsVolumeConfiguration.
            Note: The Batch Scheduler checks the compute environments that are attached to the job queue before registering a task definition with Fargate. In this scenario, the job queue is where the job is submitted. If the job requires a Windows container and the first compute environment is LINUX, the compute environment is skipped and the next compute environment is checked until a Windows-based compute environment is found.
            Note: Fargate Spot is not supported for ARM64 and Windows-based containers on Fargate. A job queue will be blocked if a Fargate ARM64 or Windows job is submitted to a job queue with only Fargate Spot compute environments. However, you can attach both FARGATE and FARGATE_SPOT compute environments to the same job queue.
          • cpuArchitecture — (String)

            The vCPU architecture. The default value is X86_64. Valid values are X86_64 and ARM64.

            Note: This parameter must be set to X86_64 for Windows containers.
            Note: Fargate Spot is not supported for ARM64 and Windows-based containers on Fargate. A job queue will be blocked if a Fargate ARM64 or Windows job is submitted to a job queue with only Fargate Spot compute environments. However, you can attach both FARGATE and FARGATE_SPOT compute environments to the same job queue.
        • repositoryCredentials — (map)

          The private repository authentication credentials to use.

          • credentialsParameter — required — (String)

            The Amazon Resource Name (ARN) of the secret containing the private repository credentials.

      • timeout — (map)

        The timeout time for jobs that are submitted with this job definition. After the amount of time you specify passes, Batch terminates your jobs if they aren't finished.

        • attemptDurationSeconds — (Integer)

          The job timeout time (in seconds) that's measured from the job attempt's startedAt timestamp. After this time passes, Batch terminates your jobs if they aren't finished. The minimum value for the timeout is 60 seconds.

          For array jobs, the timeout applies to the child jobs, not to the parent array job.

          For multi-node parallel (MNP) jobs, the timeout applies to the whole job, not to the individual nodes.

      • nodeProperties — (map)

        An object with properties that are specific to multi-node parallel jobs. When nodeProperties is used in the job definition, it can't be used in addition to containerProperties, ecsProperties, or eksProperties.

          • targetNodes — required — (String)

            The range of nodes, using node index values. A range of 0:3 indicates nodes with index values of 0 through 3. If the starting range value is omitted (:n), then 0 is used to start the range. If the ending range value is omitted (n:), then the highest possible node index is used to end the range. Your accumulative node ranges must account for all nodes (0:n). You can nest node ranges (for example, 0:10 and 4:5). In this case, the 4:5 range properties override the 0:10 properties.

          • container — (map)

            The container details for the node range.

            • image — (String)

Other repositories are specified with repository-url/image:tag . It can be 255 characters long. It can contain uppercase and lowercase letters, numbers, hyphens (-), underscores (_), colons (:), periods (.), forward slashes (/), and number signs (#). This parameter maps to Image in the Create a container section of the Docker Remote API and the IMAGE parameter of docker run.

              Note: Docker image architecture must match the processor architecture of the compute resources that they're scheduled on. For example, ARM-based Docker images can only run on ARM-based compute resources.

              • Images in Amazon ECR Public repositories use the full registry/repository[:tag] or registry/repository[@digest] naming conventions. For example, public.ecr.aws/registry_alias/my-web-app:latest .

              • Images in Amazon ECR repositories use the full registry and repository URI (for example, 123456789012.dkr.ecr.<region-name>.amazonaws.com/<repository-name>).

              • Images in official repositories on Docker Hub use a single name (for example, ubuntu or mongo).

              • Images in other repositories on Docker Hub are qualified with an organization name (for example, amazon/amazon-ecs-agent).

              • Images in other online repositories are qualified further by a domain name (for example, quay.io/assemblyline/ubuntu).

            • vcpus — (Integer)

              This parameter is deprecated, use resourceRequirements to specify the vCPU requirements for the job definition. It's not supported for jobs running on Fargate resources. For jobs running on Amazon EC2 resources, it specifies the number of vCPUs reserved for the job.

              Each vCPU is equivalent to 1,024 CPU shares. This parameter maps to CpuShares in the Create a container section of the Docker Remote API and the --cpu-shares option to docker run. The number of vCPUs must be specified but can be specified in several places. You must specify it at least once for each node.

            • memory — (Integer)

            • executionRoleArn — (String)

              The Amazon Resource Name (ARN) of the execution role that Batch can assume. For jobs that run on Fargate resources, you must provide an execution role. For more information, see Batch execution IAM role in the Batch User Guide.

            • volumes — (Array<map>)

              A list of data volumes used in a job.

              • host — (map)

                The contents of the host parameter determine whether your data volume persists on the host container instance and where it's stored. If the host parameter is empty, then the Docker daemon assigns a host path for your data volume. However, the data isn't guaranteed to persist after the containers that are associated with it stop running.

                Note: This parameter isn't applicable to jobs that are running on Fargate resources and shouldn't be provided.
                • sourcePath — (String)

                  The path on the host container instance that's presented to the container. If this parameter is empty, then the Docker daemon has assigned a host path for you. If this parameter contains a file location, then the data volume persists at the specified location on the host container instance until you delete it manually. If the source path location doesn't exist on the host container instance, the Docker daemon creates it. If the location does exist, the contents of the source path folder are exported.

                  Note: This parameter isn't applicable to jobs that run on Fargate resources. Don't provide this for these jobs.
              • name — (String)

                The name of the volume. It can be up to 255 characters long. It can contain uppercase and lowercase letters, numbers, hyphens (-), and underscores (_). This name is referenced in the sourceVolume parameter of container definition mountPoints.

              • efsVolumeConfiguration — (map)

                This parameter is specified when you're using an Amazon Elastic File System file system for job storage. Jobs that are running on Fargate resources must specify a platformVersion of at least 1.4.0.

                  The directory within the Amazon EFS file system to mount as the root directory inside the host. If this parameter is omitted, the root of the Amazon EFS volume is used instead. Specifying / has the same effect as omitting this parameter. The maximum length is 4,096 characters.

                  If an EFS access point is specified in the authorizationConfig, the root directory parameter must either be omitted or set to /, which enforces the path set on the Amazon EFS access point.

                • transitEncryption — (String)

                  Determines whether to enable encryption for Amazon EFS data in transit between the Amazon ECS host and the Amazon EFS server. Transit encryption must be enabled if Amazon EFS IAM authorization is used. If this parameter is omitted, the default value of DISABLED is used. For more information, see Encrypting data in transit in the Amazon Elastic File System User Guide.

                  Possible values include:
                  • "ENABLED"
                  • "DISABLED"
                • transitEncryptionPort — (Integer)

                  The port to use when sending encrypted data between the Amazon ECS host and the Amazon EFS server. If you don't specify a transit encryption port, it uses the port selection strategy that the Amazon EFS mount helper uses. The value must be between 0 and 65,535. For more information, see EFS mount helper in the Amazon Elastic File System User Guide.

                • authorizationConfig — (map)

                    The Amazon EFS access point ID to use. If an access point is specified, the root directory value specified in the EFSVolumeConfiguration must either be omitted or set to / which enforces the path set on the EFS access point. If an access point is used, transit encryption must be enabled in the EFSVolumeConfiguration. For more information, see Working with Amazon EFS access points in the Amazon Elastic File System User Guide.

                  • iam — (String)

                    Whether or not to use the Batch job IAM role defined in a job definition when mounting the Amazon EFS file system. If enabled, transit encryption must be enabled in the EFSVolumeConfiguration. If this parameter is omitted, the default value of DISABLED is used. For more information, see Using Amazon EFS access points in the Batch User Guide. EFS IAM authorization requires that TransitEncryption be ENABLED and that a JobRoleArn is specified.

                    Possible values include:

            • privileged — (Boolean)

              When this parameter is true, the container is given elevated permissions on the host container instance (similar to the root user). This parameter maps to Privileged in the Create a container section of the Docker Remote API and the --privileged option to docker run. The default value is false.

              Note: This parameter isn't applicable to jobs that are running on Fargate resources and shouldn't be provided, or specified as false.
            • ulimits — (Array<map>)

              A list of ulimits to set in the container. This parameter maps to Ulimits in the Create a container section of the Docker Remote API and the --ulimit option to docker run.

                The memory hard limit (in MiB) present to the container. This parameter is supported for jobs that are running on Amazon EC2 resources. If your container attempts to exceed the memory specified, the container is terminated. This parameter maps to Memory in the Create a container section of the Docker Remote API and the --memory option to docker run. You must specify at least 4 MiB of memory for a job. This is required but can be specified in several places for multi-node parallel (MNP) jobs. It must be specified for each node at least once. This parameter maps to Memory in the Create a container section of the Docker Remote API and the --memory option to docker run.

                Note: If you're trying to maximize your resource utilization by providing your jobs as much memory as possible for a particular instance type, see Memory management in the Batch User Guide.

                For jobs that are running on Fargate resources, then value is the hard limit (in MiB), and must match one of the supported values and the VCPU values must be one of the values supported for that memory value.

                • permissions — (Array<String>)

                  The explicit permissions to provide to the container for the device. By default, the container has permissions for read, write, and mknod for the device.

              • initProcessEnabled — (Boolean)

                If true, run an init process inside the container that forwards signals and reaps processes. This parameter maps to the --init option to docker run. This parameter requires version 1.25 of the Docker Remote API or greater on your container instance. To check the Docker Remote API version on your container instance, log in to your container instance and run the following command: sudo docker version | grep "Server API version"

              • sharedMemorySize — (Integer)

                The value for the size (in MiB) of the /dev/shm volume. This parameter maps to the --shm-size option to docker run.

                Note: This parameter isn't applicable to jobs that are running on Fargate resources. Don't provide it for these jobs.
              • tmpfs — (Array<map>)

                The container path, mount options, and size (in MiB) of the tmpfs mount. This parameter maps to the --tmpfs option to docker run.

                Note: This parameter isn't applicable to jobs that are running on Fargate resources. Don't provide this parameter for this resource type.
                • containerPath — required — (String)

                  The absolute file path in the container where the tmpfs volume is mounted.

                • size — required — (Integer)

                  The size (in MiB) of the tmpfs volume.

                • mountOptions — (Array<String>)

                  The list of tmpfs volume mount options.

                  Valid values: "defaults" | "ro" | "rw" | "suid" | "nosuid" | "dev" | "nodev" | "exec" | "noexec" | "sync" | "async" | "dirsync" | "remount" | "mand" | "nomand" | "atime" | "noatime" | "diratime" | "nodiratime" | "bind" | "rbind" | "unbindable" | "runbindable" | "private" | "rprivate" | "shared" | "rshared" | "slave" | "rslave" | "relatime" | "norelatime" | "strictatime" | "nostrictatime" | "mode" | "uid" | "gid" | "nr_inodes" | "nr_blocks" | "mpol"

              • maxSwap — (Integer)

                The total amount of swap memory (in MiB) a container can use. This parameter is translated to the --memory-swap option to docker run where the value is the sum of the container memory plus the maxSwap value. For more information, see --memory-swap details in the Docker documentation.

                If a maxSwap value of 0 is specified, the container doesn't use swap. Accepted values are 0 or any positive integer. If the maxSwap parameter is omitted, the container doesn't use the swap configuration for the container instance that it's running on. A maxSwap value must be set for the swappiness parameter to be used.

                Note: This parameter isn't applicable to jobs that are running on Fargate resources. Don't provide it for these jobs.
              • swappiness — (Integer)

                You can use this parameter to tune a container's memory swappiness behavior. A swappiness value of 0 causes swapping to not occur unless absolutely necessary. A swappiness value of 100 causes pages to be swapped aggressively. Valid values are whole numbers between 0 and 100. If the swappiness parameter isn't specified, a default value of 60 is used. If a value isn't specified for maxSwap, then this parameter is ignored. If maxSwap is set to 0, the container doesn't use swap. This parameter maps to the --memory-swappiness option to docker run.

                Consider the following when you use a per-container swap configuration.

                • Swap space must be enabled and allocated on the container instance for the containers to use.

                  Note: By default, the Amazon ECS optimized AMIs don't have swap enabled. You must enable swap on the instance to use this feature. For more information, see Instance store swap volumes in the Amazon EC2 User Guide for Linux Instances or How do I allocate memory to work as swap space in an Amazon EC2 instance by using a swap file?

                • The swap space parameters are only supported for job definitions using EC2 resources.

                • If the maxSwap and swappiness parameters are omitted from a job definition, each container has a default swappiness value of 60. Moreover, the total swap usage is limited to two times the memory reservation of the container.

                Note: This parameter isn't applicable to jobs that are running on Fargate resources. Don't provide it for these jobs.
            • logConfiguration — (map)

              The log configuration specification for the container.

              This parameter maps to LogConfig in the Create a container section of the Docker Remote API and the --log-driver option to docker run. By default, containers use the same logging driver that the Docker daemon uses. However the container might use a different logging driver than the Docker daemon by specifying a log driver with this parameter in the container definition. To use a different logging driver for a container, the log system must be configured properly on the container instance (or on a different log server for remote logging options). For more information on the options for different supported log drivers, see Configure logging drivers in the Docker documentation.

              Note: Batch currently supports a subset of the logging drivers available to the Docker daemon (shown in the LogConfiguration data type).

              This parameter requires version 1.18 of the Docker Remote API or greater on your container instance. To check the Docker Remote API version on your container instance, log in to your container instance and run the following command: sudo docker version | grep "Server API version"

              Note: The Amazon ECS container agent running on a container instance must register the logging drivers available on that instance with the ECS_AVAILABLE_LOGGING_DRIVERS environment variable before containers placed on that instance can use these log configuration options. For more information, see Amazon ECS container agent configuration in the Amazon Elastic Container Service Developer Guide.
              • logDriver — required — (String)

                The log driver to use for the container. The valid values that are listed for this parameter are log drivers that the Amazon ECS container agent can communicate with by default.

                The supported log drivers are awslogs, fluentd, gelf, json-file, journald, logentries, syslog, and splunk.

                Note: Jobs that are running on Fargate resources are restricted to the awslogs and splunk log drivers.

                awslogs

                Specifies the Amazon CloudWatch Logs logging driver. For more information, see Using the awslogs log driver in the Batch User Guide and Amazon CloudWatch Logs logging driver in the Docker documentation.

                fluentd

                Specifies the Fluentd logging driver. For more information including usage and options, see Fluentd logging driver in the Docker documentation.

                gelf

                Specifies the Graylog Extended Format (GELF) logging driver. For more information including usage and options, see Graylog Extended Format logging driver in the Docker documentation.

                journald

                Specifies the journald logging driver. For more information including usage and options, see Journald logging driver in the Docker documentation.

                json-file

                Specifies the JSON file logging driver. For more information including usage and options, see JSON File logging driver in the Docker documentation.

                splunk

                syslog

                Specifies the syslog logging driver. For more information including usage and options, see Syslog logging driver in the Docker documentation.

                Note: If you have a custom driver that's not listed earlier that you want to work with the Amazon ECS container agent, you can fork the Amazon ECS container agent project that's available on GitHub and customize it to work with that driver. We encourage you to submit pull requests for changes that you want to have included. However, Amazon Web Services doesn't currently support running modified copies of this software.

                This parameter requires version 1.18 of the Docker Remote API or greater on your container instance. To check the Docker Remote API version on your container instance, log in to your container instance and run the following command: sudo docker version | grep "Server API version"

                • valueFrom — required — (String)

                  The secret to expose to the container. The supported values are either the full Amazon Resource Name (ARN) of the Secrets Manager secret or the full ARN of the parameter in the Amazon Web Services Systems Manager Parameter Store.

                  Note: If the Amazon Web Services Systems Manager Parameter Store parameter exists in the same Region as the job you're launching, then you can use either the full Amazon Resource Name (ARN) or name of the parameter. If the parameter exists in a different Region, then the full ARN must be specified.
            • secrets — (Array<map>)

              The secrets for the container. For more information, see Specifying sensitive data in the Batch User Guide.

              • name — required — (String)

                Note: If the Amazon Web Services Systems Manager Parameter Store parameter exists in the same Region as the job you're launching, then you can use either the full Amazon Resource Name (ARN) or name of the parameter. If the parameter exists in a different Region, then the full ARN must be specified.
            • networkConfiguration — (map)

              The network configuration for jobs that are running on Fargate resources. Jobs that are running on Amazon EC2 resources must not specify this parameter.

              • assignPublicIp — (String)

                Indicates whether the job has a public IP address. For a job that's running on Fargate resources in a private subnet to send outbound traffic to the internet (for example, to pull container images), the private subnet requires a NAT gateway be attached to route requests to the internet. For more information, see Amazon ECS task networking in the Amazon Elastic Container Service Developer Guide. The default value is "DISABLED".

                Possible values include:
                • "ENABLED"
                • "DISABLED"
            • fargatePlatformConfiguration — (map)

              The platform configuration for jobs that are running on Fargate resources. Jobs that are running on Amazon EC2 resources must not specify this parameter.

              • platformVersion — (String)

                The Fargate platform version where the jobs are running. A platform version is specified only for jobs that are running on Fargate resources. If one isn't specified, the LATEST platform version is used by default. This uses a recent, approved version of the Fargate platform for compute resources. For more information, see Fargate platform versions in the Amazon Elastic Container Service Developer Guide.

            • ephemeralStorage — (map)

              The amount of ephemeral storage to allocate for the task. This parameter is used to expand the total amount of ephemeral storage available, beyond the default amount, for tasks hosted on Fargate.

              • sizeInGiB — required — (Integer)

                The total amount, in GiB, of ephemeral storage to set for the task. The minimum supported value is 21 GiB and the maximum supported value is 200 GiB.

                Note: The following parameters can’t be set for Windows containers: linuxParameters, privileged, user, ulimits, readonlyRootFilesystem, and efsVolumeConfiguration.
                Note: The Batch Scheduler checks the compute environments that are attached to the job queue before registering a task definition with Fargate. In this scenario, the job queue is where the job is submitted. If the job requires a Windows container and the first compute environment is LINUX, the compute environment is skipped and the next compute environment is checked until a Windows-based compute environment is found.
                Note: Fargate Spot is not supported for ARM64 and Windows-based containers on Fargate. A job queue will be blocked if a Fargate ARM64 or Windows job is submitted to a job queue with only Fargate Spot compute environments. However, you can attach both FARGATE and FARGATE_SPOT compute environments to the same job queue.
              • cpuArchitecture — (String)

                The vCPU architecture. The default value is X86_64. Valid values are X86_64 and ARM64.

                Note: This parameter must be set to X86_64 for Windows containers.
                Note: Fargate Spot is not supported for ARM64 and Windows-based containers on Fargate. A job queue will be blocked if a Fargate ARM64 or Windows job is submitted to a job queue with only Fargate Spot compute environments. However, you can attach both FARGATE and FARGATE_SPOT compute environments to the same job queue.
            • repositoryCredentials — (map)

                  • containerName — (String)

                    A unique identifier for the container.

                  • condition — (String)

                    The dependency condition of the container. The following are the available conditions and their behavior:

                    • START - This condition emulates the behavior of links and volumes today. It validates that a dependent container is started before permitting other containers to start.

                    • COMPLETE - This condition validates that a dependent container runs to completion (exits) before permitting other containers to start. This can be useful for nonessential containers that run a script and then exit. This condition can't be set on an essential container.

                    • SUCCESS - This condition is the same as COMPLETE, but it also requires that the container exits with a zero status. This condition can't be set on an essential container.

                • environment — (Array<map>)

                  The environment variables to pass to a container. This parameter maps to Env inthe Create a container section of the Docker Remote API and the --env parameter to docker run.

                  We don't recommend using plaintext environment variables for sensitive information, such as credential data.

                  Note: Environment variables cannot start with AWS_BATCH. This naming convention is reserved for variables that Batch sets.
                  • name — (String)

                    The name of the key-value pair. For environment variables, this is the name of the environment variable.

                  • value — (String)

                    The value of the key-value pair. For environment variables, this is the value of the environment variable.

                • essential — (Boolean)

                  If the essential parameter of a container is marked as true, and that container fails or stops for any reason, all other containers that are part of the task are stopped. If the essential parameter of a container is marked as false, its failure doesn't affect the rest of the containers in a task. If this parameter is omitted, a container is assumed to be essential.

                  All jobs must have at least one essential container. If you have an application that's composed of multiple containers, group containers that are used for a common purpose into components, and separate the different components into multiple task definitions. For more information, see Application Architecture in the Amazon Elastic Container Service Developer Guide.

                • image — required — (String)

                  The image used to start a container. This string is passed directly to the Docker daemon. By default, images in the Docker Hub registry are available. Other repositories are specified with either repository-url/image:tag or repository-url/image@digest. Up to 255 letters (uppercase and lowercase), numbers, hyphens, underscores, colons, periods, forward slashes, and number signs are allowed.

                  • maxSwap — (Integer)

                    The total amount of swap memory (in MiB) a container can use. This parameter is translated to the --memory-swap option to docker run where the value is the sum of the container memory plus the maxSwap value. For more information, see --memory-swap details in the Docker documentation.

                    If a maxSwap value of 0 is specified, the container doesn't use swap. Accepted values are 0 or any positive integer. If the maxSwap parameter is omitted, the container doesn't use the swap configuration for the container instance that it's running on. A maxSwap value must be set for the swappiness parameter to be used.

                    Note: This parameter isn't applicable to jobs that are running on Fargate resources. Don't provide it for these jobs.
                  • swappiness — (Integer)

                    You can use this parameter to tune a container's memory swappiness behavior. A swappiness value of 0 causes swapping to not occur unless absolutely necessary. A swappiness value of 100 causes pages to be swapped aggressively. Valid values are whole numbers between 0 and 100. If the swappiness parameter isn't specified, a default value of 60 is used. If a value isn't specified for maxSwap, then this parameter is ignored. If maxSwap is set to 0, the container doesn't use swap. This parameter maps to the --memory-swappiness option to docker run.

                    Consider the following when you use a per-container swap configuration.

                    • Swap space must be enabled and allocated on the container instance for the containers to use.

                      Note: By default, the Amazon ECS optimized AMIs don't have swap enabled. You must enable swap on the instance to use this feature. For more information, see Instance store swap volumes in the Amazon EC2 User Guide for Linux Instances or How do I allocate memory to work as swap space in an Amazon EC2 instance by using a swap file?

                    • The swap space parameters are only supported for job definitions using EC2 resources.

                    • If the maxSwap and swappiness parameters are omitted from a job definition, each container has a default swappiness value of 60. Moreover, the total swap usage is limited to two times the memory reservation of the container.

                    Note: This parameter isn't applicable to jobs that are running on Fargate resources. Don't provide it for these jobs.
                • logConfiguration — (map)

                  The log configuration specification for the container.

                  This parameter maps to LogConfig in the Create a container section of the Docker Remote API and the --log-driver option to docker run.

                  By default, containers use the same logging driver that the Docker daemon uses. However the container can use a different logging driver than the Docker daemon by specifying a log driver with this parameter in the container definition. To use a different logging driver for a container, the log system must be configured properly on the container instance (or on a different log server for remote logging options). For more information about the options for different supported log drivers, see Configure logging drivers in the Docker documentation.

                  Note: Amazon ECS currently supports a subset of the logging drivers available to the Docker daemon (shown in the LogConfiguration data type). Additional log drivers may be available in future releases of the Amazon ECS container agent.

                  This parameter requires version 1.18 of the Docker Remote API or greater on your container instance. To check the Docker Remote API version on your container instance, log in to your container instance and run the following command: sudo docker version --format '{{.Server.APIVersion}}'

                  Note: The Amazon ECS container agent running on a container instance must register the logging drivers available on that instance with the ECS_AVAILABLE_LOGGING_DRIVERS environment variable before containers placed on that instance can use these log configuration options. For more information, see Amazon ECS container agent configuration in the Amazon Elastic Container Service Developer Guide.
                  • logDriver — required — (String)

                    The log driver to use for the container. The valid values that are listed for this parameter are log drivers that the Amazon ECS container agent can communicate with by default.

                    The supported log drivers are awslogs, fluentd, gelf, json-file, journald, logentries, syslog, and splunk.

                    Note: Jobs that are running on Fargate resources are restricted to the awslogs and splunk log drivers.

                    awslogs

                    Specifies the Amazon CloudWatch Logs logging driver. For more information, see Using the awslogs log driver in the Batch User Guide and Amazon CloudWatch Logs logging driver in the Docker documentation.

                    fluentd

                    Specifies the Fluentd logging driver. For more information including usage and options, see Fluentd logging driver in the Docker documentation.

                    gelf

                    Specifies the Graylog Extended Format (GELF) logging driver. For more information including usage and options, see Graylog Extended Format logging driver in the Docker documentation.

                    journald

                    Specifies the journald logging driver. For more information including usage and options, see Journald logging driver in the Docker documentation.

                    json-file

                    Specifies the JSON file logging driver. For more information including usage and options, see JSON File logging driver in the Docker documentation.

                    splunk

                    Specifies the Splunk logging driver. For more information including usage and options, see Splunk logging driver in the Docker documentation.

                    syslog

                    Specifies the syslog logging driver. For more information including usage and options, see Syslog logging driver in the Docker documentation.

                    Note: If you have a custom driver that's not listed earlier that you want to work with the Amazon ECS container agent, you can fork the Amazon ECS container agent project that's available on GitHub and customize it to work with that driver. We encourage you to submit pull requests for changes that you want to have included. However, Amazon Web Services doesn't currently support running modified copies of this software.

                    This parameter requires version 1.18 of the Docker Remote API or greater on your container instance. To check the Docker Remote API version on your container instance, log in to your container instance and run the following command: sudo docker version | grep "Server API version"

                    Possible values include:
                    • "json-file"
                    • "syslog"
                    • "journald"
                    • "gelf"
                    • "fluentd"
                    • "awslogs"
                    • "splunk"
                  • options — (map<String>)

                    The configuration options to send to the log driver. This parameter requires version 1.19 of the Docker Remote API or greater on your container instance. To check the Docker Remote API version on your container instance, log in to your container instance and run the following command: sudo docker version | grep "Server API version"

                  • secretOptions — (Array<map>)

                    The secrets to pass to the log configuration. For more information, see Specifying sensitive data in the Batch User Guide.

                    • name — required — (String)

                      The name of the secret.

                    • valueFrom — required — (String)

                      The secret to expose to the container. The supported values are either the full Amazon Resource Name (ARN) of the Secrets Manager secret or the full ARN of the parameter in the Amazon Web Services Systems Manager Parameter Store.

                      Note: If the Amazon Web Services Systems Manager Parameter Store parameter exists in the same Region as the job you're launching, then you can use either the full Amazon Resource Name (ARN) or name of the parameter. If the parameter exists in a different Region, then the full ARN must be specified.
                • mountPoints — (Array<map>)

                  The mount points for data volumes in your container.

                  This parameter maps to Volumes in the Create a container section of the Docker Remote API and the --volume option to docker run.

                  Windows containers can mount whole directories on the same drive as $env:ProgramData. Windows containers can't mount directories on a different drive, and mount point can't be across drives.

                  • containerPath — (String)

                    The path on the container where the host volume is mounted.

                  • readOnly — (Boolean)

                    If this value is true, the container has read-only access to the volume. Otherwise, the container can write to the volume. The default value is false.

                  • sourceVolume — (String)

                    The name of the volume to mount.

                • name — (String)

                  The name of a container. The name can be used as a unique identifier to target your dependsOn and Overrides objects.

                • privileged — (Boolean)

                  When this parameter is true, the container is given elevated privileges on the host container instance (similar to the root user). This parameter maps to Privileged in the Create a container section of the Docker Remote API and the --privileged option to docker run.

                  Note: This parameter is not supported for Windows containers or tasks run on Fargate.
                • readonlyRootFilesystem — (Boolean)

                  When this parameter is true, the container is given read-only access to its root file system. This parameter maps to ReadonlyRootfs in the Create a container section of the Docker Remote API and the --read-only option to docker run.

                  Note: This parameter is not supported for Windows containers.
                • repositoryCredentials — (map)

                • resourceRequirements — (Array<map>)

                  The type and amount of a resource to assign to a container. The only supported resource is a GPU.

                  • value — required — (String)

                    The quantity of the specified resource to reserve for the container. The values vary based on the type specified.

                    type="GPU"

                    The number of physical GPUs to reserve for the container. Make sure that the number of GPUs reserved for all containers in a job doesn't exceed the number of available GPUs on the compute resource that the job is launched on.

                    Note: GPUs aren't available for jobs that are running on Fargate resources.

                    type="MEMORY"

                    The memory hard limit (in MiB) present to the container. This parameter is supported for jobs that are running on Amazon EC2 resources. If your container attempts to exceed the memory specified, the container is terminated. This parameter maps to Memory in the Create a container section of the Docker Remote API and the --memory option to docker run. You must specify at least 4 MiB of memory for a job. This is required but can be specified in several places for multi-node parallel (MNP) jobs. It must be specified for each node at least once. This parameter maps to Memory in the Create a container section of the Docker Remote API and the --memory option to docker run.

                    Note: If you're trying to maximize your resource utilization by providing your jobs as much memory as possible for a particular instance type, see Memory management in the Batch User Guide.

                    For jobs that are running on Fargate resources, then value is the hard limit (in MiB), and must match one of the supported values and the VCPU values must be one of the values supported for that memory value.

                    value = 512

                    VCPU = 0.25

                    value = 1024

                    VCPU = 16

                    type="VCPU"

                    The number of vCPUs reserved for the container. This parameter maps to CpuShares in the Create a container section of the Docker Remote API and the --cpu-shares option to docker run. Each vCPU is equivalent to 1,024 CPU shares. For Amazon EC2 resources, you must specify at least one vCPU. This is required but can be specified in several places; it must be specified for each node at least once.

                    The default for the Fargate On-Demand vCPU resource count quota is 6 vCPUs. For more information about Fargate quotas, see Fargate quotas in the Amazon Web Services General Reference.

                    For jobs that are running on Fargate resources, then value must match one of the supported values and the MEMORY values must be one of the values supported for that VCPU value. The supported values are 0.25, 0.5, 1, 2, 4, 8, and 16

                    value = 0.25

                    • "VCPU"
                    • "MEMORY"
                • secrets — (Array<map>)

                  The secrets to pass to the container. For more information, see Specifying Sensitive Data in the Amazon Elastic Container Service Developer Guide.

                  • name — required — (String)

                    The name of the secret.

                  • valueFrom — required — (String)

                    The secret to expose to the container. The supported values are either the full Amazon Resource Name (ARN) of the Secrets Manager secret or the full ARN of the parameter in the Amazon Web Services Systems Manager Parameter Store.

                    Note: If the Amazon Web Services Systems Manager Parameter Store parameter exists in the same Region as the job you're launching, then you can use either the full Amazon Resource Name (ARN) or name of the parameter. If the parameter exists in a different Region, then the full ARN must be specified.
                • ulimits — (Array<map>)

                  A list of ulimits to set in the container. If a ulimit value is specified in a task definition, it overrides the default values set by Docker. This parameter maps to Ulimits in the Create a container section of the Docker Remote API and the --ulimit option to docker run.

                  Amazon ECS tasks hosted on Fargate use the default resource limit values set by the operating system with the exception of the nofile resource limit parameter which Fargate overrides. The nofile resource limit sets a restriction on the number of open files that a container can use. The default nofile soft limit is 1024 and the default hard limit is 65535.

                  This parameter requires version 1.18 of the Docker Remote API or greater on your container instance. To check the Docker Remote API version on your container instance, log in to your container instance and run the following command: sudo docker version --format '{{.Server.APIVersion}}'

                  Note: This parameter is not supported for Windows containers.
                  • hardLimit — required — (Integer)

                    The hard limit for the ulimit type.

                    The type of the ulimit. Valid values are: core | cpu | data | fsize | locks | memlock | msgqueue | nice | nofile | nproc | rss | rtprio | rttime | sigpending | stack.

                  • softLimit — required — (Integer)

                    The soft limit for the ulimit type.

                • user — (String)

                  The user to use inside the container. This parameter maps to User in the Create a container section of the Docker Remote API and the --user option to docker run.

                  Note: When running tasks using the host network mode, don't run containers using the root user (UID 0). We recommend using a non-root user for better security.

                  You can specify the user using the following formats. If specifying a UID or GID, you must specify it as a positive integer.

                  • user

                  • user:group

                  • uid

                  • uid:gid

                  • user:gi

                  • uid:group

                  Note: This parameter is not supported for Windows containers.
              • ephemeralStorage — (map)

                The amount of ephemeral storage to allocate for the task. This parameter is used to expand the total amount of ephemeral storage available, beyond the default amount, for tasks hosted on Fargate.

                • sizeInGiB — required — (Integer)

                  The total amount, in GiB, of ephemeral storage to set for the task. The minimum supported value is 21 GiB and the maximum supported value is 200 GiB.

              • executionRoleArn — (String)

                The Amazon Resource Name (ARN) of the execution role that Batch can assume. For jobs that run on Fargate resources, you must provide an execution role. For more information, see Batch execution IAM role in the Batch User Guide.

              • platformVersion — (String)

                The Fargate platform version where the jobs are running. A platform version is specified only for jobs that are running on Fargate resources. If one isn't specified, the LATEST platform version is used by default. This uses a recent, approved version of the Fargate platform for compute resources. For more information, see Fargate platform versions in the Amazon Elastic Container Service Developer Guide.

              • ipcMode — (String)

                The IPC resource namespace to use for the containers in the task. The valid values are host, task, or none.

                If host is specified, all containers within the tasks that specified the host IPC mode on the same container instance share the same IPC resources with the host Amazon EC2 instance.

                If task is specified, all containers within the specified task share the same IPC resources.

                If none is specified, the IPC resources within the containers of a task are private, and are not shared with other containers in a task or on the container instance.

                If no value is specified, then the IPC resource namespace sharing depends on the Docker daemon setting on the container instance. For more information, see IPC settings in the Docker run reference.

              • taskRoleArn — (String)

                The Amazon Resource Name (ARN) that's associated with the Amazon ECS task.

                Note: This is object is comparable to ContainerProperties:jobRoleArn.
              • pidMode — (String)

                The process namespace to use for the containers in the task. The valid values are host or task. For example, monitoring sidecars might need pidMode to access information about other containers running in the same task.

                If host is specified, all containers within the tasks that specified the host PID mode on the same container instance share the process namespace with the host Amazon EC2 instance.

                If task is specified, all containers within the specified task share the same process namespace.

                If no value is specified, the default is a private namespace for each container. For more information, see PID settings in the Docker run reference.

              • networkConfiguration — (map)

                The network configuration for jobs that are running on Fargate resources. Jobs that are running on Amazon EC2 resources must not specify this parameter.

                • assignPublicIp — (String)

                  Indicates whether the job has a public IP address. For a job that's running on Fargate resources in a private subnet to send outbound traffic to the internet (for example, to pull container images), the private subnet requires a NAT gateway be attached to route requests to the internet. For more information, see Amazon ECS task networking in the Amazon Elastic Container Service Developer Guide. The default value is "DISABLED".

                  Possible values include:

                  The operating system for the compute environment. Valid values are: LINUX (default), WINDOWS_SERVER_2019_CORE, WINDOWS_SERVER_2019_FULL, WINDOWS_SERVER_2022_CORE, and WINDOWS_SERVER_2022_FULL.

                  Note: The following parameters can’t be set for Windows containers: linuxParameters, privileged, user, ulimits, readonlyRootFilesystem, and efsVolumeConfiguration.
                  Note: The Batch Scheduler checks the compute environments that are attached to the job queue before registering a task definition with Fargate. In this scenario, the job queue is where the job is submitted. If the job requires a Windows container and the first compute environment is LINUX, the compute environment is skipped and the next compute environment is checked until a Windows-based compute environment is found.
                  Note: Fargate Spot is not supported for ARM64 and Windows-based containers on Fargate. A job queue will be blocked if a Fargate ARM64 or Windows job is submitted to a job queue with only Fargate Spot compute environments. However, you can attach both FARGATE and FARGATE_SPOT compute environments to the same job queue.
                • cpuArchitecture — (String)

                  The vCPU architecture. The default value is X86_64. Valid values are X86_64 and ARM64.

If the host parameter is empty, then the Docker daemon assigns a host path for your data volume. However, the data isn't guaranteed to persist after the containers that are associated with it stop running.

                  Note: This parameter isn't applicable to jobs that are running on Fargate resources and shouldn't be provided.

                The dependency condition of the container. The following are the available conditions and their behavior:

                • START - This condition emulates the behavior of links and volumes today. It validates that a dependent container is started before permitting other containers to start.

                • COMPLETE - This condition validates that a dependent container runs to completion (exits) before permitting other containers to start. This can be useful for nonessential containers that run a script and then exit. This condition can't be set on an essential container.

                • SUCCESS - This condition is the same as COMPLETE, but it also requires that the container exits with a zero status. This condition can't be set on an essential container.

            • environment — (Array<map>)

              The environment variables to pass to a container. This parameter maps to Env inthe Create a container section of the Docker Remote API and the --env parameter to docker run.

              We don't recommend using plaintext environment variables for sensitive information, such as credential data.

              Note: Environment variables cannot start with AWS_BATCH. This naming convention is reserved for variables that Batch sets.
              • name — (String)

            • essential — (Boolean)

              If the essential parameter of a container is marked as true, and that container fails or stops for any reason, all other containers that are part of the task are stopped. If the essential parameter of a container is marked as false, its failure doesn't affect the rest of the containers in a task. If this parameter is omitted, a container is assumed to be essential.

              All jobs must have at least one essential container. If you have an application that's composed of multiple containers, group containers that are used for a common purpose into components, and separate the different components into multiple task definitions. For more information, see Application Architecture in the Amazon Elastic Container Service Developer Guide.

            • image — required — (String)

              The image used to start a container. This string is passed directly to the Docker daemon. By default, images in the Docker Hub registry are available. Other repositories are specified with either repository-url/image:tag or repository-url/image@digest. Up to 255 letters (uppercase and lowercase), numbers, hyphens, underscores, colons, periods, forward slashes, and number signs are allowed. This parameter maps to Image in the Create a container section of the Docker Remote API and the IMAGE parameter of the docker run .

            • linuxParameters — (map)

              • initProcessEnabled — (Boolean)

                If true, run an init process inside the container that forwards signals and reaps processes. This parameter maps to the --init option to docker run. This parameter requires version 1.25 of the Docker Remote API or greater on your container instance. To check the Docker Remote API version on your container instance, log in to your container instance and run the following command: sudo docker version | grep "Server API version"

              • sharedMemorySize — (Integer)

                The value for the size (in MiB) of the /dev/shm volume. This parameter maps to the --shm-size option to docker run.

                Note: This parameter isn't applicable to jobs that are running on Fargate resources. Don't provide it for these jobs.
              • tmpfs — (Array<map>)

                The container path, mount options, and size (in MiB) of the tmpfs mount. This parameter maps to the --tmpfs option to docker run.

                Note: This parameter isn't applicable to jobs that are running on Fargate resources. Don't provide this parameter for this resource type.
                • containerPath — required — (String)

                  The absolute file path in the container where the tmpfs volume is mounted.

                • size — required — (Integer)

              • maxSwap — (Integer)

                The total amount of swap memory (in MiB) a container can use. This parameter is translated to the --memory-swap option to docker run where the value is the sum of the container memory plus the maxSwap value. For more information, see --memory-swap details in the Docker documentation.

                If a maxSwap value of 0 is specified, the container doesn't use swap. Accepted values are 0 or any positive integer. If the maxSwap parameter is omitted, the container doesn't use the swap configuration for the container instance that it's running on. A maxSwap value must be set for the swappiness parameter to be used.

                Note: This parameter isn't applicable to jobs that are running on Fargate resources. Don't provide it for these jobs.
              • swappiness — (Integer)

                You can use this parameter to tune a container's memory swappiness behavior. A swappiness value of 0 causes swapping to not occur unless absolutely necessary. A swappiness value of 100 causes pages to be swapped aggressively. Valid values are whole numbers between 0 and 100. If the swappiness parameter isn't specified, a default value of 60 is used. If a value isn't specified for maxSwap, then this parameter is ignored. If maxSwap is set to 0, the container doesn't use swap. This parameter maps to the --memory-swappiness option to docker run.

                Consider the following when you use a per-container swap configuration.

                • Swap space must be enabled and allocated on the container instance for the containers to use.

                  Note: By default, the Amazon ECS optimized AMIs don't have swap enabled. You must enable swap on the instance to use this feature. For more information, see Instance store swap volumes in the Amazon EC2 User Guide for Linux Instances or How do I allocate memory to work as swap space in an Amazon EC2 instance by using a swap file?

                • The swap space parameters are only supported for job definitions using EC2 resources.

                • If the maxSwap and swappiness parameters are omitted from a job definition, each container has a default swappiness value of 60. Moreover, the total swap usage is limited to two times the memory reservation of the container.

                Note: This parameter isn't applicable to jobs that are running on Fargate resources. Don't provide it for these jobs.
            • logConfiguration — (map)

              The log configuration specification for the container.

              This parameter maps to LogConfig in the Create a container section of the Docker Remote API and the --log-driver option to docker run.

              By default, containers use the same logging driver that the Docker daemon uses. However the container can use a different logging driver than the Docker daemon by specifying a log driver with this parameter in the container definition. To use a different logging driver for a container, the log system must be configured properly on the container instance (or on a different log server for remote logging options). For more information about the options for different supported log drivers, see Configure logging drivers in the Docker documentation.

              Note: Amazon ECS currently supports a subset of the logging drivers available to the Docker daemon (shown in the LogConfiguration data type). Additional log drivers may be available in future releases of the Amazon ECS container agent.

              This parameter requires version 1.18 of the Docker Remote API or greater on your container instance. To check the Docker Remote API version on your container instance, log in to your container instance and run the following command: sudo docker version --format '{{.Server.APIVersion}}'

              Note: The Amazon ECS container agent running on a container instance must register the logging drivers available on that instance with the ECS_AVAILABLE_LOGGING_DRIVERS environment variable before containers placed on that instance can use these log configuration options. For more information, see Amazon ECS container agent configuration in the Amazon Elastic Container Service Developer Guide.
              • logDriver — required — (String)

                The log driver to use for the container. The valid values that are listed for this parameter are log drivers that the Amazon ECS container agent can communicate with by default.

                The supported log drivers are awslogs, fluentd, gelf, json-file, journald, logentries, syslog, and splunk.

                Note: Jobs that are running on Fargate resources are restricted to the awslogs and splunk log drivers.

                awslogs

                Specifies the Amazon CloudWatch Logs logging driver. For more information, see Using the awslogs log driver in the Batch User Guide and Amazon CloudWatch Logs logging driver in the Docker documentation.

                json-file

                Specifies the JSON file logging driver. For more information including usage and options, see JSON File logging driver in the Docker documentation.

                splunk

                Specifies the Splunk logging driver. For more information including usage and options, see Splunk logging driver in the Docker documentation.

                syslog

                Specifies the syslog logging driver. For more information including usage and options, see Syslog logging driver in the Docker documentation.

                Note: If you have a custom driver that's not listed earlier that you want to work with the Amazon ECS container agent, you can fork the Amazon ECS container agent project that's available on GitHub and customize it to work with that driver. We encourage you to submit pull requests for changes that you want to have included. However, Amazon Web Services doesn't currently support running modified copies of this software.

                This parameter requires version 1.18 of the Docker Remote API or greater on your container instance. To check the Docker Remote API version on your container instance, log in to your container instance and run the following command: sudo docker version | grep "Server API version"

                • valueFrom — required — (String)

                  The secret to expose to the container. The supported values are either the full Amazon Resource Name (ARN) of the Secrets Manager secret or the full ARN of the parameter in the Amazon Web Services Systems Manager Parameter Store.

                  Note: If the Amazon Web Services Systems Manager Parameter Store parameter exists in the same Region as the job you're launching, then you can use either the full Amazon Resource Name (ARN) or name of the parameter. If the parameter exists in a different Region, then the full ARN must be specified.
            • mountPoints — (Array<map>)

              The mount points for data volumes in your container.

              This parameter maps to Volumes in the Create a container section of the Docker Remote API and the --volume option to docker run.

              Windows containers can mount whole directories on the same drive as $env:ProgramData. Windows containers can't mount directories on a different drive, and mount point can't be across drives.

                The name of the volume to mount.

            • name — (String)

              The name of a container. The name can be used as a unique identifier to target your dependsOn and Overrides objects.

            • privileged — (Boolean)

              When this parameter is true, the container is given elevated privileges on the host container instance (similar to the root user). This parameter maps to Privileged in the Create a container section of the Docker Remote API and the --privileged option to docker run.

              Note: This parameter is not supported for Windows containers or tasks run on Fargate.
            • readonlyRootFilesystem — (Boolean)

              When this parameter is true, the container is given read-only access to its root file system. This parameter maps to ReadonlyRootfs in the Create a container section of the Docker Remote API and the --read-only option to docker run.

              Note: This parameter is not supported for Windows containers.
            • repositoryCredentials — (map)

                type="MEMORY"

                The memory hard limit (in MiB) present to the container. This parameter is supported for jobs that are running on Amazon EC2 resources. If your container attempts to exceed the memory specified, the container is terminated. This parameter maps to Memory in the Create a container section of the Docker Remote API and the --memory option to docker run. You must specify at least 4 MiB of memory for a job. This is required but can be specified in several places for multi-node parallel (MNP) jobs. It must be specified for each node at least once. This parameter maps to Memory in the Create a container section of the Docker Remote API and the --memory option to docker run.

                Note: If you're trying to maximize your resource utilization by providing your jobs as much memory as possible for a particular instance type, see Memory management in the Batch User Guide.

                For jobs that are running on Fargate resources, then value is the hard limit (in MiB), and must match one of the supported values and the VCPU values must be one of the values supported for that memory value.

                type="VCPU"

                The number of vCPUs reserved for the container. This parameter maps to CpuShares in the Create a container section of the Docker Remote API and the --cpu-shares option to docker run. Each vCPU is equivalent to 1,024 CPU shares. For Amazon EC2 resources, you must specify at least one vCPU. This is required but can be specified in several places; it must be specified for each node at least once.

                The default for the Fargate On-Demand vCPU resource count quota is 6 vCPUs. For more information about Fargate quotas, see Fargate quotas in the Amazon Web Services General Reference.

                For jobs that are running on Fargate resources, then value must match one of the supported values and the MEMORY values must be one of the values supported for that VCPU value. The supported values are 0.25, 0.5, 1, 2, 4, 8, and 16

              • type — required — (String)

                The type of resource to assign to a container. The supported resources include GPU, MEMORY, and VCPU.

                Possible values include:
                • "GPU"
                • "VCPU"
                • "MEMORY"
            • secrets — (Array<map>)

              The secrets to pass to the container. For more information, see Specifying Sensitive Data in the Amazon Elastic Container Service Developer Guide.

              • name — required — (String)

                The name of the secret.

              • valueFrom — required — (String)

                The secret to expose to the container. The supported values are either the full Amazon Resource Name (ARN) of the Secrets Manager secret or the full ARN of the parameter in the Amazon Web Services Systems Manager Parameter Store.

                Note: If the Amazon Web Services Systems Manager Parameter Store parameter exists in the same Region as the job you're launching, then you can use either the full Amazon Resource Name (ARN) or name of the parameter. If the parameter exists in a different Region, then the full ARN must be specified.
            • ulimits — (Array<map>)

              A list of ulimits to set in the container. If a ulimit value is specified in a task definition, it overrides the default values set by Docker. This parameter maps to Ulimits in the Create a container section of the Docker Remote API and the --ulimit option to docker run.

              Amazon ECS tasks hosted on Fargate use the default resource limit values set by the operating system with the exception of the nofile resource limit parameter which Fargate overrides. The nofile resource limit sets a restriction on the number of open files that a container can use. The default nofile soft limit is 1024 and the default hard limit is 65535.

              This parameter requires version 1.18 of the Docker Remote API or greater on your container instance. To check the Docker Remote API version on your container instance, log in to your container instance and run the following command: sudo docker version --format '{{.Server.APIVersion}}'

              Note: This parameter is not supported for Windows containers.
              • hardLimit — required — (Integer)

                The hard limit for the ulimit type.

              • name — required — (String)

                The type of the ulimit. Valid values are: core | cpu | data | fsize | locks | memlock | msgqueue | nice | nofile | nproc | rss | rtprio | rttime | sigpending | stack.

              • softLimit — required — (Integer)

                The soft limit for the ulimit type.

            • user — (String)

              The user to use inside the container. This parameter maps to User in the Create a container section of the Docker Remote API and the --user option to docker run.

              Note: When running tasks using the host network mode, don't run containers using the root user (UID 0). We recommend using a non-root user for better security.

              You can specify the user using the following formats. If specifying a UID or GID, you must specify it as a positive integer.

              • user

              • user:group

              • uid

              • uid:gid

              • user:gi

              • uid:group

              Note: This parameter is not supported for Windows containers.
          • ephemeralStorage — (map)

            The amount of ephemeral storage to allocate for the task. This parameter is used to expand the total amount of ephemeral storage available, beyond the default amount, for tasks hosted on Fargate.

            • sizeInGiB — required — (Integer)

              The total amount, in GiB, of ephemeral storage to set for the task. The minimum supported value is 21 GiB and the maximum supported value is 200 GiB.

          • executionRoleArn — (String)

            The Amazon Resource Name (ARN) of the execution role that Batch can assume. For jobs that run on Fargate resources, you must provide an execution role. For more information, see Batch execution IAM role in the Batch User Guide.

          • platformVersion — (String)

            The Fargate platform version where the jobs are running. A platform version is specified only for jobs that are running on Fargate resources. If one isn't specified, the LATEST platform version is used by default. This uses a recent, approved version of the Fargate platform for compute resources. For more information, see Fargate platform versions in the Amazon Elastic Container Service Developer Guide.

          • ipcMode — (String)

            The IPC resource namespace to use for the containers in the task. The valid values are host, task, or none.

            If host is specified, all containers within the tasks that specified the host IPC mode on the same container instance share the same IPC resources with the host Amazon EC2 instance.

            If task is specified, all containers within the specified task share the same IPC resources.

            If none is specified, the IPC resources within the containers of a task are private, and are not shared with other containers in a task or on the container instance.

            If no value is specified, then the IPC resource namespace sharing depends on the Docker daemon setting on the container instance. For more information, see IPC settings in the Docker run reference.

          • taskRoleArn — (String)

            The Amazon Resource Name (ARN) that's associated with the Amazon ECS task.

            Note: This is object is comparable to ContainerProperties:jobRoleArn.
          • pidMode — (String)

            The process namespace to use for the containers in the task. The valid values are host or task. For example, monitoring sidecars might need pidMode to access information about other containers running in the same task.

            If host is specified, all containers within the tasks that specified the host PID mode on the same container instance share the process namespace with the host Amazon EC2 instance.

            If task is specified, all containers within the specified task share the same process namespace.

            If no value is specified, the default is a private namespace for each container. For more information, see PID settings in the Docker run reference.

          • networkConfiguration — (map)

            The network configuration for jobs that are running on Fargate resources. Jobs that are running on Amazon EC2 resources must not specify this parameter.

            • assignPublicIp — (String)

              Indicates whether the job has a public IP address. For a job that's running on Fargate resources in a private subnet to send outbound traffic to the internet (for example, to pull container images), the private subnet requires a NAT gateway be attached to route requests to the internet. For more information, see Amazon ECS task networking in the Amazon Elastic Container Service Developer Guide. The default value is "DISABLED".

              Possible values include:
              • "ENABLED"
              • "DISABLED"
          • runtimePlatform — (map)

            An object that represents the compute environment architecture for Batch jobs on Fargate.

            • operatingSystemFamily — (String)

              The operating system for the compute environment. Valid values are: LINUX (default), WINDOWS_SERVER_2019_CORE, WINDOWS_SERVER_2019_FULL, WINDOWS_SERVER_2022_CORE, and WINDOWS_SERVER_2022_FULL.

              Note: The following parameters can’t be set for Windows containers: linuxParameters, privileged, user, ulimits, readonlyRootFilesystem, and efsVolumeConfiguration.
              Note: The Batch Scheduler checks the compute environments that are attached to the job queue before registering a task definition with Fargate. In this scenario, the job queue is where the job is submitted. If the job requires a Windows container and the first compute environment is LINUX, the compute environment is skipped and the next compute environment is checked until a Windows-based compute environment is found.
              Note: Fargate Spot is not supported for ARM64 and Windows-based containers on Fargate. A job queue will be blocked if a Fargate ARM64 or Windows job is submitted to a job queue with only Fargate Spot compute environments. However, you can attach both FARGATE and FARGATE_SPOT compute environments to the same job queue.
            • cpuArchitecture — (String)

              The vCPU architecture. The default value is X86_64. Valid values are X86_64 and ARM64.

              Note: This parameter must be set to X86_64 for Windows containers.
              Note: Fargate Spot is not supported for ARM64 and Windows-based containers on Fargate. A job queue will be blocked if a Fargate ARM64 or Windows job is submitted to a job queue with only Fargate Spot compute environments. However, you can attach both FARGATE and FARGATE_SPOT compute environments to the same job queue.
          • volumes — (Array<map>)

            A list of volumes that are associated with the job.

            • host — (map)

              The contents of the host parameter determine whether your data volume persists on the host container instance and where it's stored. If the host parameter is empty, then the Docker daemon assigns a host path for your data volume. However, the data isn't guaranteed to persist after the containers that are associated with it stop running.

              Note: This parameter isn't applicable to jobs that are running on Fargate resources and shouldn't be provided.
              • sourcePath — (String)

                The path on the host container instance that's presented to the container. If this parameter is empty, then the Docker daemon has assigned a host path for you. If this parameter contains a file location, then the data volume persists at the specified location on the host container instance until you delete it manually. If the source path location doesn't exist on the host container instance, the Docker daemon creates it. If the location does exist, the contents of the source path folder are exported.

                Note: This parameter isn't applicable to jobs that run on Fargate resources. Don't provide this for these jobs.
            • name — (String)

              The name of the volume. It can be up to 255 characters long. It can contain uppercase and lowercase letters, numbers, hyphens (-), and underscores (_). This name is referenced in the sourceVolume parameter of container definition mountPoints.

            • efsVolumeConfiguration — (map)

              This parameter is specified when you're using an Amazon Elastic File System file system for job storage. Jobs that are running on Fargate resources must specify a platformVersion of at least 1.4.0.

              • fileSystemId — required — (String)

                The Amazon EFS file system ID to use.

              • rootDirectory — (String)

                The directory within the Amazon EFS file system to mount as the root directory inside the host. If this parameter is omitted, the root of the Amazon EFS volume is used instead. Specifying / has the same effect as omitting this parameter. The maximum length is 4,096 characters.

                If an EFS access point is specified in the authorizationConfig, the root directory parameter must either be omitted or set to /, which enforces the path set on the Amazon EFS access point.

              • transitEncryption — (String)

                Determines whether to enable encryption for Amazon EFS data in transit between the Amazon ECS host and the Amazon EFS server. Transit encryption must be enabled if Amazon EFS IAM authorization is used. If this parameter is omitted, the default value of DISABLED is used. For more information, see Encrypting data in transit in the Amazon Elastic File System User Guide.

                Possible values include:
                • "ENABLED"
                • "DISABLED"
              • transitEncryptionPort — (Integer)

                The port to use when sending encrypted data between the Amazon ECS host and the Amazon EFS server. If you don't specify a transit encryption port, it uses the port selection strategy that the Amazon EFS mount helper uses. The value must be between 0 and 65,535. For more information, see EFS mount helper in the Amazon Elastic File System User Guide.

              • authorizationConfig — (map)

                The authorization configuration details for the Amazon EFS file system.

                • accessPointId — (String)

                  The Amazon EFS access point ID to use. If an access point is specified, the root directory value specified in the EFSVolumeConfiguration must either be omitted or set to / which enforces the path set on the EFS access point. If an access point is used, transit encryption must be enabled in the EFSVolumeConfiguration. For more information, see Working with Amazon EFS access points in the Amazon Elastic File System User Guide.

                • iam — (String)

                  Whether or not to use the Batch job IAM role defined in a job definition when mounting the Amazon EFS file system. If enabled, transit encryption must be enabled in the EFSVolumeConfiguration. If this parameter is omitted, the default value of DISABLED is used. For more information, see Using Amazon EFS access points in the Batch User Guide. EFS IAM authorization requires that TransitEncryption be ENABLED and that a JobRoleArn is specified.

                  Possible values include:
                  • "ENABLED"
                  • "DISABLED"
      • eksProperties — (map)

          • serviceAccountName — (String)

            The name of the service account that's used to run the pod. For more information, see Kubernetes service accounts and Configure a Kubernetes service account to assume an IAM role in the Amazon EKS User Guide and Configure service accounts for pods in the Kubernetes documentation.

          • hostNetwork — (Boolean)

            Indicates if the pod uses the hosts' network IP address. The default value is true. Setting this to false enables the Kubernetes pod networking model. Most Batch workloads are egress-only and don't require the overhead of IP allocation for each pod for incoming connections. For more information, see Host namespaces and Pod networking in the Kubernetes documentation.

          • dnsPolicy — (String)

            The DNS policy for the pod. The default value is ClusterFirst. If the hostNetwork parameter is not specified, the default is ClusterFirstWithHostNet. ClusterFirst indicates that any DNS query that does not match the configured cluster domain suffix is forwarded to the upstream nameserver inherited from the node. For more information, see Pod's DNS policy in the Kubernetes documentation.

            Valid values: Default | ClusterFirst | ClusterFirstWithHostNet

          • imagePullSecrets — (Array<map>)

            References a Kubernetes secret resource. It holds a list of secrets. These secrets help to gain access to pull an images from a private registry.

              The Docker image used to start the container.

            • imagePullPolicy — (String)

              The image pull policy for the container. Supported values are Always, IfNotPresent, and Never. This parameter defaults to IfNotPresent. However, if the :latest tag is specified, it defaults to Always. For more information, see Updating images in the Kubernetes documentation.

            • command — (Array<String>)

              The entrypoint for the container. This isn't run within a shell. If this isn't specified, the ENTRYPOINT of the container image is used. Environment variable references are expanded using the container's environment.

              If the referenced environment variable doesn't exist, the reference in the command isn't changed. For example, if the reference is to "$(NAME1)" and the NAME1 environment variable doesn't exist, the command string will remain "$(NAME1)." $$ is replaced with $ and the resulting string isn't expanded. For example, $$(VAR_NAME) will be passed as $(VAR_NAME) whether or not the VAR_NAME environment variable exists. The entrypoint can't be updated. For more information, see ENTRYPOINT in the Dockerfile reference and Define a command and arguments for a container and Entrypoint in the Kubernetes documentation.

            • args — (Array<String>)

              An array of arguments to the entrypoint. If this isn't specified, the CMD of the container image is used. This corresponds to the args member in the Entrypoint portion of the Pod in Kubernetes. Environment variable references are expanded using the container's environment.

              If the referenced environment variable doesn't exist, the reference in the command isn't changed. For example, if the reference is to "$(NAME1)" and the NAME1 environment variable doesn't exist, the command string will remain "$(NAME1)." $$ is replaced with $, and the resulting string isn't expanded. For example, $$(VAR_NAME) is passed as $(VAR_NAME) whether or not the VAR_NAME environment variable exists. For more information, see Dockerfile reference: CMD and Define a command and arguments for a pod in the Kubernetes documentation.

            • env — (Array<map>)

              The environment variables to pass to a container.
