Properties

ContainerProperties

An object with properties specific to Amazon ECS-based jobs. When containerProperties is used in the job definition, it can't be used in addition to eksProperties, ecsProperties, or nodeProperties.

Required: No

Type: ContainerProperties

Update requires: No interruption

EcsProperties

An object that contains the properties for the Amazon ECS resources of a job.When ecsProperties is used in the job definition, it can't be used in addition to containerProperties, eksProperties, or nodeProperties.

Required: No

Type: EcsProperties

Update requires: No interruption

EksProperties

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

Required: No

Type: EksProperties

Update requires: No interruption

JobDefinitionName

The name of the job definition.

Required: No

Type: String

Update requires: Replacement

NodeProperties

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.

Note

If the job runs on Fargate resources, don't specify nodeProperties. Use containerProperties instead.

Required: No

Type: NodeProperties

Update requires: No interruption

Parameters

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 AWS Batch User Guide.

Required: No

Type: Json

Update requires: No interruption

PlatformCapabilities

The platform capabilities required by the job definition. If no value is specified, it defaults to EC2. Jobs run on Fargate resources specify FARGATE.

Required: No

Type: Array of String

Update requires: No interruption

PropagateTags

Specifies whether to propagate the tags from the job or job definition to the corresponding Amazon ECS task. If no value is specified, the tags aren't propagated. Tags can only be propagated to the tasks when the tasks are created. For tags with the same name, job tags are given priority over job definitions tags. If the total number of combined tags from the job and job definition is over 50, the job is moved to the FAILED state.

Required: No

Type: Boolean

Update requires: No interruption

RetryStrategy

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

Required: No

Type: RetryStrategy

Update requires: No interruption

SchedulingPriority

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.

Required: No

Type: Integer

Update requires: No interruption

Tags

The tags that are applied to the job definition.

Required: No

Type: Array of Tag

Update requires: Replacement

Timeout

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

Required: No

Type: Timeout

Update requires: No interruption

Type

The type of job definition. For more information about multi-node parallel jobs, see Creating a multi-node parallel job definition in the AWS Batch User Guide.

If the value is container, then one of the following is required: containerProperties, ecsProperties, or eksProperties.
If the value is multinode, then nodeProperties is required.

Note

If the job is run on Fargate resources, then multinode isn't supported.

Required: Yes

Type: String

Allowed values: container | multinode

Update requires: No interruption

Return values

Ref

When you pass the logical ID of this resource to the intrinsic Ref function, Ref returns the job definition ARN, such as arn:aws:batch:us-east-1:111122223333:job-definition/test-gpu:2.

For more information about using the Ref function, see Ref.

Fn::GetAtt

The Fn::GetAtt intrinsic function returns a value for a specified attribute of this type. The following are the available attributes and sample return values.

For more information about using the Fn::GetAtt intrinsic function, see Fn::GetAtt.

Examples

Test nvidia-smi

The following example tests the nvidia-smi command on a GPU instance to verify that the GPU is working inside the container. For more information, see Test GPU Functionality in the AWS Batch User Guide .
