delete-service¶

Description¶

Deletes a specified service within a cluster. You can delete a service if you have no running tasks in it and the desired task count is zero. If the service is actively maintaining tasks, you can't delete it, and you must update the service to a desired task count of zero. For more information, see UpdateService .

Note

When you delete a service, if there are still running tasks that require cleanup, the service status moves from ACTIVE to DRAINING , and the service is no longer visible in the console or in the ListServices API operation. After all tasks have transitioned to either STOPPING or STOPPED status, the service status moves from DRAINING to INACTIVE . Services in the DRAINING or INACTIVE status can still be viewed with the DescribeServices API operation. However, in the future, INACTIVE services may be cleaned up and purged from Amazon ECS record keeping, and DescribeServices calls on those services return a ServiceNotFoundException error.

Warning

If you attempt to create a new service with the same name as an existing service in either ACTIVE or DRAINING status, you receive an error.

Options¶

--cluster (string)

The short name or full Amazon Resource Name (ARN) of the cluster that hosts the service to delete. If you do not specify a cluster, the default cluster is assumed.

--service (string)

The name of the service to delete.

--force | --no-force (boolean)

If true , allows you to delete a service even if it wasn't scaled down to zero tasks. It's only necessary to use this if the service uses the REPLICA scheduling strategy.

--cli-input-json (string) Performs service operation based on the JSON string provided. The JSON string follows the format provided by --generate-cli-skeleton. If other arguments are provided on the command line, the CLI values will override the JSON-provided values. It is not possible to pass arbitrary binary values using a JSON-provided value as the string will be taken literally.

--generate-cli-skeleton (string) Prints a JSON skeleton to standard output without sending an API request. If provided with no value or the value input, prints a sample input JSON that can be used as an argument for --cli-input-json. If provided with the value output, it validates the command inputs and returns a sample output JSON for that command.

Global Options¶

--debug (boolean)

Turn on debug logging.

--endpoint-url (string)

Override command's default URL with the given URL.

--no-verify-ssl (boolean)

By default, the AWS CLI uses SSL when communicating with AWS services. For each SSL connection, the AWS CLI will verify SSL certificates. This option overrides the default behavior of verifying SSL certificates.

--no-paginate (boolean)

Disable automatic pagination. If automatic pagination is disabled, the AWS CLI will only make one call, for the first page of results.

--output (string)

The formatting style for command output.

json
text
table

--ca-bundle (string)

The CA certificate bundle to use when verifying SSL certificates. Overrides config/env settings.

--cli-read-timeout (int)

The maximum socket read time in seconds. If the value is set to 0, the socket read will be blocking and not timeout. The default value is 60 seconds.

--cli-connect-timeout (int)

The maximum socket connect time in seconds. If the value is set to 0, the socket connect will be blocking and not timeout. The default value is 60 seconds.

Examples¶

Note

To use the following examples, you must have the AWS CLI installed and configured. See the Getting started guide in the AWS CLI User Guide for more information.

Unless otherwise stated, all examples have unix-like quotation rules. These examples will need to be adapted to your terminal's quoting rules. See Using quotation marks with strings in the AWS CLI User Guide .

To delete a service

The following ecs delete-service example deletes the specified service from a cluster. You can include the --force parameter to delete a service even if it has not been scaled to zero tasks.

aws ecs delete-service --cluster MyCluster --service MyService1 --force

For more information, see Deleting a Service in the Amazon ECS Developer Guide.

Output¶

service -> (structure)

The full description of the deleted service.

serviceArn -> (string)

The ARN that identifies the service. For more information about the ARN format, see Amazon Resource Name (ARN) in the Amazon ECS Developer Guide .

serviceName -> (string)

The name of your service. Up to 255 letters (uppercase and lowercase), numbers, underscores, and hyphens are allowed. Service names must be unique within a cluster. However, you can have similarly named services in multiple clusters within a Region or across multiple Regions.

clusterArn -> (string)

The Amazon Resource Name (ARN) of the cluster that hosts the service.

loadBalancers -> (list)

A list of Elastic Load Balancing load balancer objects. It contains the load balancer name, the container name, and the container port to access from the load balancer. The container name is as it appears in a container definition.

(structure)

The load balancer configuration to use with a service or task set.

When you add, update, or remove a load balancer configuration, Amazon ECS starts a new deployment with the updated Elastic Load Balancing configuration. This causes tasks to register to and deregister from load balancers.

We recommend that you verify this on a test environment before you update the Elastic Load Balancing configuration.

A service-linked role is required for services that use multiple target groups. For more information, see Using service-linked roles in the Amazon Elastic Container Service Developer Guide .

targetGroupArn -> (string)

The full Amazon Resource Name (ARN) of the Elastic Load Balancing target group or groups associated with a service or task set.

A target group ARN is only specified when using an Application Load Balancer or Network Load Balancer.

For services using the ECS deployment controller, you can specify one or multiple target groups. For more information, see Registering multiple target groups with a service in the Amazon Elastic Container Service Developer Guide .

For services using the CODE_DEPLOY deployment controller, you're required to define two target groups for the load balancer. For more information, see Blue/green deployment with CodeDeploy in the Amazon Elastic Container Service Developer Guide .

Warning
If your service's task definition uses the awsvpc network mode, you must choose ip as the target type, not instance . Do this when creating your target groups because tasks that use the awsvpc network mode are associated with an elastic network interface, not an Amazon EC2 instance. This network mode is required for the Fargate launch type.

loadBalancerName -> (string)

The name of the load balancer to associate with the Amazon ECS service or task set.

If you are using an Application Load Balancer or a Network Load Balancer the load balancer name parameter should be omitted.

containerName -> (string)

The name of the container (as it appears in a container definition) to associate with the load balancer.

You need to specify the container name when configuring the target group for an Amazon ECS load balancer.

containerPort -> (integer)

The port on the container to associate with the load balancer. This port must correspond to a containerPort in the task definition the tasks in the service are using. For tasks that use the EC2 launch type, the container instance they're launched on must allow ingress traffic on the hostPort of the port mapping.

serviceRegistries -> (list)

The details for the service discovery registries to assign to this service. For more information, see Service Discovery .

(structure)

The details for the service registry.

Each service may be associated with one service registry. Multiple service registries for each service are not supported.

When you add, update, or remove the service registries configuration, Amazon ECS starts a new deployment. New tasks are registered and deregistered to the updated service registry configuration.

registryArn -> (string)

The Amazon Resource Name (ARN) of the service registry. The currently supported service registry is Cloud Map. For more information, see CreateService .

port -> (integer)

The port value used if your service discovery service specified an SRV record. This field might be used if both the awsvpc network mode and SRV records are used.

containerName -> (string)

The container name value to be used for your service discovery service. It's already specified in the task definition. If the task definition that your service task specifies uses the bridge or host network mode, you must specify a containerName and containerPort combination from the task definition. If the task definition that your service task specifies uses the awsvpc network mode and a type SRV DNS record is used, you must specify either a containerName and containerPort combination or a port value. However, you can't specify both.

containerPort -> (integer)

The port value to be used for your service discovery service. It's already specified in the task definition. If the task definition your service task specifies uses the bridge or host network mode, you must specify a containerName and containerPort combination from the task definition. If the task definition your service task specifies uses the awsvpc network mode and a type SRV DNS record is used, you must specify either a containerName and containerPort combination or a port value. However, you can't specify both.

status -> (string)

The status of the service. The valid values are ACTIVE , DRAINING , or INACTIVE .

desiredCount -> (integer)

The desired number of instantiations of the task definition to keep running on the service. This value is specified when the service is created with CreateService , and it can be modified with UpdateService .

runningCount -> (integer)

The number of tasks in the cluster that are in the RUNNING state.

pendingCount -> (integer)

The number of tasks in the cluster that are in the PENDING state.

launchType -> (string)

The launch type the service is using. When using the DescribeServices API, this field is omitted if the service was created using a capacity provider strategy.

capacityProviderStrategy -> (list)

The capacity provider strategy the service uses. When using the DescribeServices API, this field is omitted if the service was created using a launch type.

(structure)

The details of a capacity provider strategy. A capacity provider strategy can be set when using the RunTask or CreateCluster APIs or as the default capacity provider strategy for a cluster with the CreateCluster API.

Only capacity providers that are already associated with a cluster and have an ACTIVE or UPDATING status can be used in a capacity provider strategy. The PutClusterCapacityProviders API is used to associate a capacity provider with a cluster.

If specifying a capacity provider that uses an Auto Scaling group, the capacity provider must already be created. New Auto Scaling group capacity providers can be created with the CreateClusterCapacityProvider API operation.

To use a Fargate capacity provider, specify either the FARGATE or FARGATE_SPOT capacity providers. The Fargate capacity providers are available to all accounts and only need to be associated with a cluster to be used in a capacity provider strategy.

With FARGATE_SPOT , you can run interruption tolerant tasks at a rate that's discounted compared to the FARGATE price. FARGATE_SPOT runs tasks on spare compute capacity. When Amazon Web Services needs the capacity back, your tasks are interrupted with a two-minute warning. FARGATE_SPOT supports Linux tasks with the X86_64 architecture on platform version 1.3.0 or later. FARGATE_SPOT supports Linux tasks with the ARM64 architecture on platform version 1.4.0 or later.

A capacity provider strategy can contain a maximum of 20 capacity providers.

capacityProvider -> (string)

The short name of the capacity provider.

weight -> (integer)

The weight value designates the relative percentage of the total number of tasks launched that should use the specified capacity provider. The weight value is taken into consideration after the base value, if defined, is satisfied.

If no weight value is specified, the default value of 0 is used. When multiple capacity providers are specified within a capacity provider strategy, at least one of the capacity providers must have a weight value greater than zero and any capacity providers with a weight of 0 can't be used to place tasks. If you specify multiple capacity providers in a strategy that all have a weight of 0 , any RunTask or CreateService actions using the capacity provider strategy will fail.

An example scenario for using weights is defining a strategy that contains two capacity providers and both have a weight of 1 , then when the base is satisfied, the tasks will be split evenly across the two capacity providers. Using that same logic, if you specify a weight of 1 for capacityProviderA and a weight of 4 for capacityProviderB , then for every one task that's run using capacityProviderA , four tasks would use capacityProviderB .

base -> (integer)

The base value designates how many tasks, at a minimum, to run on the specified capacity provider. Only one capacity provider in a capacity provider strategy can have a base defined. If no value is specified, the default value of 0 is used.

platformVersion -> (string)

The platform version to run your service on. A platform version is only specified for tasks that are hosted on Fargate. If one isn't specified, the LATEST platform version is used. For more information, see Fargate Platform Versions in the Amazon Elastic Container Service Developer Guide .

platformFamily -> (string)

The operating system that your tasks in the service run on. A platform family is specified only for tasks using the Fargate launch type.

All tasks that run as part of this service must use the same platformFamily value as the service (for example, LINUX ).

taskDefinition -> (string)

The task definition to use for tasks in the service. This value is specified when the service is created with CreateService , and it can be modified with UpdateService .

deploymentConfiguration -> (structure)

Optional deployment parameters that control how many tasks run during the deployment and the ordering of stopping and starting tasks.

deploymentCircuitBreaker -> (structure)

Note
The deployment circuit breaker can only be used for services using the rolling update (ECS ) deployment type.

The deployment circuit breaker determines whether a service deployment will fail if the service can't reach a steady state. If you use the deployment circuit breaker, a service deployment will transition to a failed state and stop launching new tasks. If you use the rollback option, when a service deployment fails, the service is rolled back to the last deployment that completed successfully. For more information, see Rolling update in the Amazon Elastic Container Service Developer Guide

enable -> (boolean)

Determines whether to use the deployment circuit breaker logic for the service.

rollback -> (boolean)

Determines whether to configure Amazon ECS to roll back the service if a service deployment fails. If rollback is on, when a service deployment fails, the service is rolled back to the last deployment that completed successfully.

maximumPercent -> (integer)

If a service is using the rolling update (ECS ) deployment type, the maximumPercent parameter represents an upper limit on the number of your service's tasks that are allowed in the RUNNING or PENDING state during a deployment, as a percentage of the desiredCount (rounded down to the nearest integer). This parameter enables you to define the deployment batch size. For example, if your service is using the REPLICA service scheduler and has a desiredCount of four tasks and a maximumPercent value of 200%, the scheduler may start four new tasks before stopping the four older tasks (provided that the cluster resources required to do this are available). The default maximumPercent value for a service using the REPLICA service scheduler is 200%.

The Amazon ECS scheduler uses this parameter to replace unhealthy tasks by starting replacement tasks first and then stopping the unhealthy tasks, as long as cluster resources for starting replacement tasks are available. For more information about how the scheduler replaces unhealthy tasks, see Amazon ECS services .

If a service is using either the blue/green (CODE_DEPLOY ) or EXTERNAL deployment types, and tasks in the service use the EC2 launch type, the maximum percent value is set to the default value. The maximum percent value is used to define the upper limit on the number of the tasks in the service that remain in the RUNNING state while the container instances are in the DRAINING state.

Note
You can't specify a custom maximumPercent value for a service that uses either the blue/green (CODE_DEPLOY ) or EXTERNAL deployment types and has tasks that use the EC2 launch type.

If the tasks in the service use the Fargate launch type, the maximum percent value is not used, although it is returned when describing your service.

minimumHealthyPercent -> (integer)

If a service is using the rolling update (ECS ) deployment type, the minimumHealthyPercent represents a lower limit on the number of your service's tasks that must remain in the RUNNING state during a deployment, as a percentage of the desiredCount (rounded up to the nearest integer). This parameter enables you to deploy without using additional cluster capacity. For example, if your service has a desiredCount of four tasks and a minimumHealthyPercent of 50%, the service scheduler may stop two existing tasks to free up cluster capacity before starting two new tasks.

If any tasks are unhealthy and if maximumPercent doesn't allow the Amazon ECS scheduler to start replacement tasks, the scheduler stops the unhealthy tasks one-by-one — using the minimumHealthyPercent as a constraint — to clear up capacity to launch replacement tasks. For more information about how the scheduler replaces unhealthy tasks, see Amazon ECS services .

For services that do not use a load balancer, the following should be noted:

A service is considered healthy if all essential containers within the tasks in the service pass their health checks.

If a task has no essential containers with a health check defined, the service scheduler will wait for 40 seconds after a task reaches a RUNNING state before the task is counted towards the minimum healthy percent total.

If a task has one or more essential containers with a health check defined, the service scheduler will wait for the task to reach a healthy status before counting it towards the minimum healthy percent total. A task is considered healthy when all essential containers within the task have passed their health checks. The amount of time the service scheduler can wait for is determined by the container health check settings.

For services that do use a load balancer, the following should be noted:

If a task has no essential containers with a health check defined, the service scheduler will wait for the load balancer target group health check to return a healthy status before counting the task towards the minimum healthy percent total.

If a task has an essential container with a health check defined, the service scheduler will wait for both the task to reach a healthy status and the load balancer target group health check to return a healthy status before counting the task towards the minimum healthy percent total.

The default value for a replica service for minimumHealthyPercent is 100%. The default minimumHealthyPercent value for a service using the DAEMON service schedule is 0% for the CLI, the Amazon Web Services SDKs, and the APIs and 50% for the Amazon Web Services Management Console.

The minimum number of healthy tasks during a deployment is the desiredCount multiplied by the minimumHealthyPercent /100, rounded up to the nearest integer value.

If a service is using either the blue/green (CODE_DEPLOY ) or EXTERNAL deployment types and is running tasks that use the EC2 launch type, the minimum healthy percent value is set to the default value. The minimum healthy percent value is used to define the lower limit on the number of the tasks in the service that remain in the RUNNING state while the container instances are in the DRAINING state.

Note
You can't specify a custom minimumHealthyPercent value for a service that uses either the blue/green (CODE_DEPLOY ) or EXTERNAL deployment types and has tasks that use the EC2 launch type.

If a service is using either the blue/green (CODE_DEPLOY ) or EXTERNAL deployment types and is running tasks that use the Fargate launch type, the minimum healthy percent value is not used, although it is returned when describing your service.

alarms -> (structure)

Information about the CloudWatch alarms.

alarmNames -> (list)

One or more CloudWatch alarm names. Use a "," to separate the alarms.

(string)

rollback -> (boolean)

Determines whether to configure Amazon ECS to roll back the service if a service deployment fails. If rollback is used, when a service deployment fails, the service is rolled back to the last deployment that completed successfully.

The task definition that the task set is using.

computedDesiredCount -> (integer)

The computed desired count for the task set. This is calculated by multiplying the service's desiredCount by the task set's scale percentage. The result is always rounded up. For example, if the computed desired count is 1.2, it rounds up to 2 tasks.

pendingCount -> (integer)

The number of tasks in the task set that are in the PENDING status during a deployment. A task in the PENDING state is preparing to enter the RUNNING state. A task set enters the PENDING status when it launches for the first time or when it's restarted after being in the STOPPED state.

(structure)

The details of a capacity provider strategy. A capacity provider strategy can be set when using the RunTask or CreateCluster APIs or as the default capacity provider strategy for a cluster with the CreateCluster API.

Only capacity providers that are already associated with a cluster and have an ACTIVE or UPDATING status can be used in a capacity provider strategy. The PutClusterCapacityProviders API is used to associate a capacity provider with a cluster.

If specifying a capacity provider that uses an Auto Scaling group, the capacity provider must already be created. New Auto Scaling group capacity providers can be created with the CreateClusterCapacityProvider API operation.

To use a Fargate capacity provider, specify either the FARGATE or FARGATE_SPOT capacity providers. The Fargate capacity providers are available to all accounts and only need to be associated with a cluster to be used in a capacity provider strategy.

With FARGATE_SPOT , you can run interruption tolerant tasks at a rate that's discounted compared to the FARGATE price. FARGATE_SPOT runs tasks on spare compute capacity. When Amazon Web Services needs the capacity back, your tasks are interrupted with a two-minute warning. FARGATE_SPOT supports Linux tasks with the X86_64 architecture on platform version 1.3.0 or later. FARGATE_SPOT supports Linux tasks with the ARM64 architecture on platform version 1.4.0 or later.

A capacity provider strategy can contain a maximum of 20 capacity providers.

capacityProvider -> (string)

The short name of the capacity provider.

weight -> (integer)

The weight value designates the relative percentage of the total number of tasks launched that should use the specified capacity provider. The weight value is taken into consideration after the base value, if defined, is satisfied.

If no weight value is specified, the default value of 0 is used. When multiple capacity providers are specified within a capacity provider strategy, at least one of the capacity providers must have a weight value greater than zero and any capacity providers with a weight of 0 can't be used to place tasks. If you specify multiple capacity providers in a strategy that all have a weight of 0 , any RunTask or CreateService actions using the capacity provider strategy will fail.

An example scenario for using weights is defining a strategy that contains two capacity providers and both have a weight of 1 , then when the base is satisfied, the tasks will be split evenly across the two capacity providers. Using that same logic, if you specify a weight of 1 for capacityProviderA and a weight of 4 for capacityProviderB , then for every one task that's run using capacityProviderA , four tasks would use capacityProviderB .

base -> (integer)

The base value designates how many tasks, at a minimum, to run on the specified capacity provider. Only one capacity provider in a capacity provider strategy can have a base defined. If no value is specified, the default value of 0 is used.

The IDs of the security groups associated with the task or service. If you don't specify a security group, the default security group for the VPC is used. There's a limit of 5 security groups that can be specified per awsvpcConfiguration .

Note
All specified security groups must be from the same VPC.

(string)

assignPublicIp -> (string)

Whether the task's elastic network interface receives a public IP address. The default value is ENABLED .

loadBalancers -> (list)

Details on a load balancer that are used with a task set.

(structure)

The load balancer configuration to use with a service or task set.

When you add, update, or remove a load balancer configuration, Amazon ECS starts a new deployment with the updated Elastic Load Balancing configuration. This causes tasks to register to and deregister from load balancers.

We recommend that you verify this on a test environment before you update the Elastic Load Balancing configuration.

A service-linked role is required for services that use multiple target groups. For more information, see Using service-linked roles in the Amazon Elastic Container Service Developer Guide .

targetGroupArn -> (string)

The full Amazon Resource Name (ARN) of the Elastic Load Balancing target group or groups associated with a service or task set.

A target group ARN is only specified when using an Application Load Balancer or Network Load Balancer.

For services using the ECS deployment controller, you can specify one or multiple target groups. For more information, see Registering multiple target groups with a service in the Amazon Elastic Container Service Developer Guide .

For services using the CODE_DEPLOY deployment controller, you're required to define two target groups for the load balancer. For more information, see Blue/green deployment with CodeDeploy in the Amazon Elastic Container Service Developer Guide .

Warning
If your service's task definition uses the awsvpc network mode, you must choose ip as the target type, not instance . Do this when creating your target groups because tasks that use the awsvpc network mode are associated with an elastic network interface, not an Amazon EC2 instance. This network mode is required for the Fargate launch type.

loadBalancerName -> (string)

The name of the load balancer to associate with the Amazon ECS service or task set.

If you are using an Application Load Balancer or a Network Load Balancer the load balancer name parameter should be omitted.

containerName -> (string)

The name of the container (as it appears in a container definition) to associate with the load balancer.

You need to specify the container name when configuring the target group for an Amazon ECS load balancer.

containerPort -> (integer)

The port on the container to associate with the load balancer. This port must correspond to a containerPort in the task definition the tasks in the service are using. For tasks that use the EC2 launch type, the container instance they're launched on must allow ingress traffic on the hostPort of the port mapping.

serviceRegistries -> (list)

The details for the service discovery registries to assign to this task set. For more information, see Service discovery .

(structure)

The details for the service registry.

Each service may be associated with one service registry. Multiple service registries for each service are not supported.

When you add, update, or remove the service registries configuration, Amazon ECS starts a new deployment. New tasks are registered and deregistered to the updated service registry configuration.

registryArn -> (string)

The Amazon Resource Name (ARN) of the service registry. The currently supported service registry is Cloud Map. For more information, see CreateService .

port -> (integer)

The port value used if your service discovery service specified an SRV record. This field might be used if both the awsvpc network mode and SRV records are used.

containerName -> (string)

The container name value to be used for your service discovery service. It's already specified in the task definition. If the task definition that your service task specifies uses the bridge or host network mode, you must specify a containerName and containerPort combination from the task definition. If the task definition that your service task specifies uses the awsvpc network mode and a type SRV DNS record is used, you must specify either a containerName and containerPort combination or a port value. However, you can't specify both.

containerPort -> (integer)

The port value to be used for your service discovery service. It's already specified in the task definition. If the task definition your service task specifies uses the bridge or host network mode, you must specify a containerName and containerPort combination from the task definition. If the task definition your service task specifies uses the awsvpc network mode and a type SRV DNS record is used, you must specify either a containerName and containerPort combination or a port value. However, you can't specify both.

scale -> (structure)

A floating-point percentage of your desired number of tasks to place and keep running in the task set.

value -> (double)

The value, specified as a percent total of a service's desiredCount , to scale the task set. Accepted values are numbers between 0 and 100.

unit -> (string)

The unit of measure for the scale value.

stabilityStatus -> (string)

The stability status. This indicates whether the task set has reached a steady state. If the following conditions are met, the task set are in STEADY_STATE :

The task runningCount is equal to the computedDesiredCount .

The pendingCount is 0 .

There are no tasks that are running on container instances in the DRAINING status.

All tasks are reporting a healthy status from the load balancers, service discovery, and container health checks.

If any of those conditions aren't met, the stability status returns STABILIZING .

stabilityStatusAt -> (timestamp)

The Unix timestamp for the time when the task set stability status was retrieved.

tags -> (list)

The metadata that you apply to the task set to help you categorize and organize them. Each tag consists of a key and an optional value. You define both.

The following basic restrictions apply to tags:

Maximum number of tags per resource - 50

For each resource, each tag key must be unique, and each tag key can have only one value.

Maximum key length - 128 Unicode characters in UTF-8

Maximum value length - 256 Unicode characters in UTF-8

If your tagging schema is used across multiple services and resources, remember that other services may have restrictions on allowed characters. Generally allowed characters are: letters, numbers, and spaces representable in UTF-8, and the following characters: + - = . _ : / @.

Tag keys and values are case-sensitive.

Do not use aws: , AWS: , or any upper or lowercase combination of such as a prefix for either keys or values as it is reserved for Amazon Web Services use. You cannot edit or delete tag keys or values with this prefix. Tags with this prefix do not count against your tags per resource limit.

(structure)

The metadata that you apply to a resource to help you categorize and organize them. Each tag consists of a key and an optional value. You define them.

The following basic restrictions apply to tags:

Maximum number of tags per resource - 50

For each resource, each tag key must be unique, and each tag key can have only one value.

Maximum key length - 128 Unicode characters in UTF-8

Maximum value length - 256 Unicode characters in UTF-8

If your tagging schema is used across multiple services and resources, remember that other services may have restrictions on allowed characters. Generally allowed characters are: letters, numbers, and spaces representable in UTF-8, and the following characters: + - = . _ : / @.

Tag keys and values are case-sensitive.

Do not use aws: , AWS: , or any upper or lowercase combination of such as a prefix for either keys or values as it is reserved for Amazon Web Services use. You cannot edit or delete tag keys or values with this prefix. Tags with this prefix do not count against your tags per resource limit.

key -> (string)

One part of a key-value pair that make up a tag. A key is a general label that acts like a category for more specific tag values.

value -> (string)

The optional part of a key-value pair that make up a tag. A value acts as a descriptor within a tag category (key).

fargateEphemeralStorage -> (structure)

The Fargate ephemeral storage settings for the task set.

kmsKeyId -> (string)

Specify an Key Management Service key ID to encrypt the ephemeral storage for deployment.

deployments -> (list)

The current state of deployments for the service.

(structure)

The details of an Amazon ECS service deployment. This is used only when a service uses the ECS deployment controller type.

id -> (string)

The ID of the deployment.

status -> (string)

The status of the deployment. The following describes each state.

PRIMARY

The most recent deployment of a service.

ACTIVE

A service deployment that still has running tasks, but are in the process of being replaced with a new PRIMARY deployment.

INACTIVE

A deployment that has been completely replaced.

taskDefinition -> (string)

The most recent task definition that was specified for the tasks in the service to use.

desiredCount -> (integer)

The most recent desired count of tasks that was specified for the service to deploy or maintain.

pendingCount -> (integer)

The number of tasks in the deployment that are in the PENDING status.

runningCount -> (integer)

The number of tasks in the deployment that are in the RUNNING status.

failedTasks -> (integer)

The number of consecutively failed tasks in the deployment. A task is considered a failure if the service scheduler can't launch the task, the task doesn't transition to a RUNNING state, or if it fails any of its defined health checks and is stopped.

Note
Once a service deployment has one or more successfully running tasks, the failed task count resets to zero and stops being evaluated.

createdAt -> (timestamp)

The Unix timestamp for the time when the service deployment was created.

updatedAt -> (timestamp)

The Unix timestamp for the time when the service deployment was last updated.

capacityProviderStrategy -> (list)

The capacity provider strategy that the deployment is using.

(structure)

The details of a capacity provider strategy. A capacity provider strategy can be set when using the RunTask or CreateCluster APIs or as the default capacity provider strategy for a cluster with the CreateCluster API.

Only capacity providers that are already associated with a cluster and have an ACTIVE or UPDATING status can be used in a capacity provider strategy. The PutClusterCapacityProviders API is used to associate a capacity provider with a cluster.

If specifying a capacity provider that uses an Auto Scaling group, the capacity provider must already be created. New Auto Scaling group capacity providers can be created with the CreateClusterCapacityProvider API operation.

To use a Fargate capacity provider, specify either the FARGATE or FARGATE_SPOT capacity providers. The Fargate capacity providers are available to all accounts and only need to be associated with a cluster to be used in a capacity provider strategy.

With FARGATE_SPOT , you can run interruption tolerant tasks at a rate that's discounted compared to the FARGATE price. FARGATE_SPOT runs tasks on spare compute capacity. When Amazon Web Services needs the capacity back, your tasks are interrupted with a two-minute warning. FARGATE_SPOT supports Linux tasks with the X86_64 architecture on platform version 1.3.0 or later. FARGATE_SPOT supports Linux tasks with the ARM64 architecture on platform version 1.4.0 or later.

A capacity provider strategy can contain a maximum of 20 capacity providers.

capacityProvider -> (string)

The short name of the capacity provider.

weight -> (integer)

The weight value designates the relative percentage of the total number of tasks launched that should use the specified capacity provider. The weight value is taken into consideration after the base value, if defined, is satisfied.

If no weight value is specified, the default value of 0 is used. When multiple capacity providers are specified within a capacity provider strategy, at least one of the capacity providers must have a weight value greater than zero and any capacity providers with a weight of 0 can't be used to place tasks. If you specify multiple capacity providers in a strategy that all have a weight of 0 , any RunTask or CreateService actions using the capacity provider strategy will fail.

An example scenario for using weights is defining a strategy that contains two capacity providers and both have a weight of 1 , then when the base is satisfied, the tasks will be split evenly across the two capacity providers. Using that same logic, if you specify a weight of 1 for capacityProviderA and a weight of 4 for capacityProviderB , then for every one task that's run using capacityProviderA , four tasks would use capacityProviderB .

base -> (integer)

The base value designates how many tasks, at a minimum, to run on the specified capacity provider. Only one capacity provider in a capacity provider strategy can have a base defined. If no value is specified, the default value of 0 is used.

launchType -> (string)

The launch type the tasks in the service are using. For more information, see Amazon ECS Launch Types in the Amazon Elastic Container Service Developer Guide .

platformVersion -> (string)

The platform version that your tasks in the service run on. A platform version is only specified for tasks using the Fargate launch type. If one isn't specified, the LATEST platform version is used. For more information, see Fargate Platform Versions in the Amazon Elastic Container Service Developer Guide .

platformFamily -> (string)

The operating system that your tasks in the service, or tasks are running on. A platform family is specified only for tasks using the Fargate launch type.

All tasks that run as part of this service must use the same platformFamily value as the service, for example, LINUX. .

networkConfiguration -> (structure)

The VPC subnet and security group configuration for tasks that receive their own elastic network interface by using the awsvpc networking mode.

awsvpcConfiguration -> (structure)

The VPC subnets and security groups that are associated with a task.

Note
All specified subnets and security groups must be from the same VPC.

subnets -> (list)

The IDs of the subnets associated with the task or service. There's a limit of 16 subnets that can be specified per awsvpcConfiguration .

Note
All specified subnets must be from the same VPC.

(string)

securityGroups -> (list)

The IDs of the security groups associated with the task or service. If you don't specify a security group, the default security group for the VPC is used. There's a limit of 5 security groups that can be specified per awsvpcConfiguration .

Note
All specified security groups must be from the same VPC.

(string)

assignPublicIp -> (string)

Whether the task's elastic network interface receives a public IP address. The default value is ENABLED .

rolloutState -> (string)

Note
The rolloutState of a service is only returned for services that use the rolling update (ECS ) deployment type that aren't behind a Classic Load Balancer.

The rollout state of the deployment. When a service deployment is started, it begins in an IN_PROGRESS state. When the service reaches a steady state, the deployment transitions to a COMPLETED state. If the service fails to reach a steady state and circuit breaker is turned on, the deployment transitions to a FAILED state. A deployment in FAILED state doesn't launch any new tasks. For more information, see DeploymentCircuitBreaker .

rolloutStateReason -> (string)

A description of the rollout state of a deployment.

serviceConnectConfiguration -> (structure)

The details of the Service Connect configuration that's used by this deployment. Compare the configuration between multiple deployments when troubleshooting issues with new deployments.

The configuration for this service to discover and connect to services, and be discovered by, and connected from, other services within a namespace.

Tasks that run in a namespace can use short names to connect to services in the namespace. Tasks can connect to services across all of the clusters in the namespace. Tasks connect through a managed proxy container that collects logs and metrics for increased visibility. Only the tasks that Amazon ECS services create are supported with Service Connect. For more information, see Service Connect in the Amazon Elastic Container Service Developer Guide .

enabled -> (boolean)

Specifies whether to use Service Connect with this service.

namespace -> (string)

The namespace name or full Amazon Resource Name (ARN) of the Cloud Map namespace for use with Service Connect. The namespace must be in the same Amazon Web Services Region as the Amazon ECS service and cluster. The type of namespace doesn't affect Service Connect. For more information about Cloud Map, see Working with Services in the Cloud Map Developer Guide .

services -> (list)

The list of Service Connect service objects. These are names and aliases (also known as endpoints) that are used by other Amazon ECS services to connect to this service.

This field is not required for a "client" Amazon ECS service that's a member of a namespace only to connect to other services within the namespace. An example of this would be a frontend application that accepts incoming requests from either a load balancer that's attached to the service or by other means.

An object selects a port from the task definition, assigns a name for the Cloud Map service, and a list of aliases (endpoints) and ports for client applications to refer to this service.

(structure)

The Service Connect service object configuration. For more information, see Service Connect in the Amazon Elastic Container Service Developer Guide .

portName -> (string)

The portName must match the name of one of the portMappings from all the containers in the task definition of this Amazon ECS service.

discoveryName -> (string)

The discoveryName is the name of the new Cloud Map service that Amazon ECS creates for this Amazon ECS service. This must be unique within the Cloud Map namespace. The name can contain up to 64 characters. The name can include lowercase letters, numbers, underscores (_), and hyphens (-). The name can't start with a hyphen.

If the discoveryName isn't specified, the port mapping name from the task definition is used in portName.namespace .

clientAliases -> (list)

The list of client aliases for this Service Connect service. You use these to assign names that can be used by client applications. The maximum number of client aliases that you can have in this list is 1.

Each alias ("endpoint") is a fully-qualified name and port number that other Amazon ECS tasks ("clients") can use to connect to this service.

Each name and port mapping must be unique within the namespace.

For each ServiceConnectService , you must provide at least one clientAlias with one port .

(structure)

Each alias ("endpoint") is a fully-qualified name and port number that other tasks ("clients") can use to connect to this service.

Each name and port mapping must be unique within the namespace.

Tasks that run in a namespace can use short names to connect to services in the namespace. Tasks can connect to services across all of the clusters in the namespace. Tasks connect through a managed proxy container that collects logs and metrics for increased visibility. Only the tasks that Amazon ECS services create are supported with Service Connect. For more information, see Service Connect in the Amazon Elastic Container Service Developer Guide .

port -> (integer)

The listening port number for the Service Connect proxy. This port is available inside of all of the tasks within the same namespace.

To avoid changing your applications in client Amazon ECS services, set this to the same port that the client application uses by default. For more information, see Service Connect in the Amazon Elastic Container Service Developer Guide .

dnsName -> (string)

The dnsName is the name that you use in the applications of client tasks to connect to this service. The name must be a valid DNS name but doesn't need to be fully-qualified. The name can include up to 127 characters. The name can include lowercase letters, numbers, underscores (_), hyphens (-), and periods (.). The name can't start with a hyphen.

If this parameter isn't specified, the default value of discoveryName.namespace is used. If the discoveryName isn't specified, the port mapping name from the task definition is used in portName.namespace .

To avoid changing your applications in client Amazon ECS services, set this to the same name that the client application uses by default. For example, a few common names are database , db , or the lowercase name of a database, such as mysql or redis . For more information, see Service Connect in the Amazon Elastic Container Service Developer Guide .

ingressPortOverride -> (integer)

The port number for the Service Connect proxy to listen on.

Use the value of this field to bypass the proxy for traffic on the port number specified in the named portMapping in the task definition of this application, and then use it in your VPC security groups to allow traffic into the proxy for this Amazon ECS service.

In awsvpc mode and Fargate, the default value is the container port number. The container port number is in the portMapping in the task definition. In bridge mode, the default value is the ephemeral port of the Service Connect proxy.

timeout -> (structure)

A reference to an object that represents the configured timeouts for Service Connect.

idleTimeoutSeconds -> (integer)

The amount of time in seconds a connection will stay active while idle. A value of 0 can be set to disable idleTimeout .

The idleTimeout default for HTTP /HTTP2 /GRPC is 5 minutes.

The idleTimeout default for TCP is 1 hour.

perRequestTimeoutSeconds -> (integer)

The amount of time waiting for the upstream to respond with a complete response per request. A value of 0 can be set to disable perRequestTimeout . perRequestTimeout can only be set if Service Connect appProtocol isn't TCP . Only idleTimeout is allowed for TCP appProtocol .

The Amazon Web Services Key Management Service key.

roleArn -> (string)

The Amazon Resource Name (ARN) of the IAM role that's associated with the Service Connect TLS.

logConfiguration -> (structure)

The log configuration for the container. This parameter maps to LogConfig in the docker container create command 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 configuration in the container definition.

Understand the following when specifying a log configuration for your containers.

Amazon ECS currently supports a subset of the logging drivers available to the Docker daemon. Additional log drivers may be available in future releases of the Amazon ECS container agent. For tasks on Fargate, the supported log drivers are awslogs , splunk , and awsfirelens . For tasks hosted on Amazon EC2 instances, the supported log drivers are awslogs , fluentd , gelf , json-file , journald ,``syslog`` , splunk , and awsfirelens .

This parameter requires version 1.18 of the Docker Remote API or greater on your container instance.

For tasks that are hosted on Amazon EC2 instances, the Amazon ECS container agent must register the available logging drivers 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 .

For tasks that are on Fargate, because you don't have access to the underlying infrastructure your tasks are hosted on, any additional software needed must be installed outside of the task. For example, the Fluentd output aggregators or a remote host running Logstash to send Gelf logs to.

logDriver -> (string)

The log driver to use for the container.

For tasks on Fargate, the supported log drivers are awslogs , splunk , and awsfirelens .

For tasks hosted on Amazon EC2 instances, the supported log drivers are awslogs , fluentd , gelf , json-file , journald , syslog , splunk , and awsfirelens .

For more information about using the awslogs log driver, see Send Amazon ECS logs to CloudWatch in the Amazon Elastic Container Service Developer Guide .

For more information about using the awsfirelens log driver, see Send Amazon ECS logs to an Amazon Web Services service or Amazon Web Services Partner .

Note
If you have a custom driver that isn't listed, 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 would like to have included. However, we don't currently provide support for running modified copies of this software.

options -> (map)

The configuration options to send to the log driver.

The options you can specify depend on the log driver. Some of the options you can specify when you use the awslogs log driver to route logs to Amazon CloudWatch include the following:

awslogs-create-group

Required: No

Specify whether you want the log group to be created automatically. If this option isn't specified, it defaults to false .

Note
Your IAM policy must include the logs:CreateLogGroup permission before you attempt to use awslogs-create-group .

awslogs-region

Required: Yes

Specify the Amazon Web Services Region that the awslogs log driver is to send your Docker logs to. You can choose to send all of your logs from clusters in different Regions to a single region in CloudWatch Logs. This is so that they're all visible in one location. Otherwise, you can separate them by Region for more granularity. Make sure that the specified log group exists in the Region that you specify with this option.

awslogs-group

Required: Yes

Make sure to specify a log group that the awslogs log driver sends its log streams to.

awslogs-stream-prefix

Required: Yes, when using the Fargate launch type.Optional for the EC2 launch type, required for the Fargate launch type.

Use the awslogs-stream-prefix option to associate a log stream with the specified prefix, the container name, and the ID of the Amazon ECS task that the container belongs to. If you specify a prefix with this option, then the log stream takes the format prefix-name/container-name/ecs-task-id .

If you don't specify a prefix with this option, then the log stream is named after the container ID that's assigned by the Docker daemon on the container instance. Because it's difficult to trace logs back to the container that sent them with just the Docker container ID (which is only available on the container instance), we recommend that you specify a prefix with this option.

For Amazon ECS services, you can use the service name as the prefix. Doing so, you can trace log streams to the service that the container belongs to, the name of the container that sent them, and the ID of the task that the container belongs to.

You must specify a stream-prefix for your logs to have your logs appear in the Log pane when using the Amazon ECS console.

awslogs-datetime-format

Required: No

This option defines a multiline start pattern in Python strftime format. A log message consists of a line that matches the pattern and any following lines that don’t match the pattern. The matched line is the delimiter between log messages.

One example of a use case for using this format is for parsing output such as a stack dump, which might otherwise be logged in multiple entries. The correct pattern allows it to be captured in a single entry.

For more information, see awslogs-datetime-format .

You cannot configure both the awslogs-datetime-format and awslogs-multiline-pattern options.

Note
Multiline logging performs regular expression parsing and matching of all log messages. This might have a negative impact on logging performance.

awslogs-multiline-pattern

Required: No

This option defines a multiline start pattern that uses a regular expression. A log message consists of a line that matches the pattern and any following lines that don’t match the pattern. The matched line is the delimiter between log messages.

For more information, see awslogs-multiline-pattern .

This option is ignored if awslogs-datetime-format is also configured.

You cannot configure both the awslogs-datetime-format and awslogs-multiline-pattern options.

Note
Multiline logging performs regular expression parsing and matching of all log messages. This might have a negative impact on logging performance.

mode

Required: No

Valid values: non-blocking | blocking

This option defines the delivery mode of log messages from the container to CloudWatch Logs. The delivery mode you choose affects application availability when the flow of logs from container to CloudWatch is interrupted.

If you use the blocking mode and the flow of logs to CloudWatch is interrupted, calls from container code to write to the stdout and stderr streams will block. The logging thread of the application will block as a result. This may cause the application to become unresponsive and lead to container healthcheck failure.

If you use the non-blocking mode, the container's logs are instead stored in an in-memory intermediate buffer configured with the max-buffer-size option. This prevents the application from becoming unresponsive when logs cannot be sent to CloudWatch. We recommend using this mode if you want to ensure service availability and are okay with some log loss. For more information, see Preventing log loss with non-blocking mode in the ``awslogs` container log driver <http://aws.amazon.com/blogs/containers/preventing-log-loss-with-non-blocking-mode-in-the-awslogs-container-log-driver/>`__ .

max-buffer-size

Required: No

Default value: 1m

When non-blocking mode is used, the max-buffer-size log option controls the size of the buffer that's used for intermediate message storage. Make sure to specify an adequate buffer size based on your application. When the buffer fills up, further logs cannot be stored. Logs that cannot be stored are lost.

To route logs using the splunk log router, you need to specify a splunk-token and a splunk-url .

When you use the awsfirelens log router to route logs to an Amazon Web Services Service or Amazon Web Services Partner Network destination for log storage and analytics, you can set the log-driver-buffer-limit option to limit the number of events that are buffered in memory, before being sent to the log router container. It can help to resolve potential log loss issue because high throughput might result in memory running out for the buffer inside of Docker.

Other options you can specify when using awsfirelens to route logs depend on the destination. When you export logs to Amazon Data Firehose, you can specify the Amazon Web Services Region with region and a name for the log stream with delivery_stream .

When you export logs to Amazon Kinesis Data Streams, you can specify an Amazon Web Services Region with region and a data stream name with stream .

When you export logs to Amazon OpenSearch Service, you can specify options like Name , Host (OpenSearch Service endpoint without protocol), Port , Index , Type , Aws_auth , Aws_region , Suppress_Type_Name , and tls .

When you export logs to Amazon S3, you can specify the bucket using the bucket option. You can also specify region , total_file_size , upload_timeout , and use_put_object as options.

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 --format '{{.Server.APIVersion}}'

key -> (string)

value -> (string)

secretOptions -> (list)

Note
If the SSM Parameter Store parameter exists in the same Region as the task you're launching, then you can use either the full ARN or name of the parameter. If the parameter exists in a different Region, then the full ARN must be specified.

serviceConnectResources -> (list)

The list of Service Connect resources that are associated with this deployment. Each list entry maps a discovery name to a Cloud Map service name.

(structure)

The Service Connect resource. Each configuration maps a discovery name to a Cloud Map service name. The data is stored in Cloud Map as part of the Service Connect configuration for each discovery name of this Amazon ECS service.

A task can resolve the dnsName for each of the clientAliases of a service. However a task can't resolve the discovery names. If you want to connect to a service, refer to the ServiceConnectConfiguration of that service for the list of clientAliases that you can use.

discoveryName -> (string)

The discovery name of this Service Connect resource.

The discoveryName is the name of the new Cloud Map service that Amazon ECS creates for this Amazon ECS service. This must be unique within the Cloud Map namespace. The name can contain up to 64 characters. The name can include lowercase letters, numbers, underscores (_), and hyphens (-). The name can't start with a hyphen.

If the discoveryName isn't specified, the port mapping name from the task definition is used in portName.namespace .

discoveryArn -> (string)

The Amazon Resource Name (ARN) for the namespace in Cloud Map that matches the discovery name for this Service Connect resource. You can use this ARN in other integrations with Cloud Map. However, Service Connect can't ensure connectivity outside of Amazon ECS.

managedEBSVolume -> (structure)

The configuration for the Amazon EBS volume that Amazon ECS creates and manages on your behalf. These settings are used to create each Amazon EBS volume, with one volume created for each task in the service. The Amazon EBS volumes are visible in your account in the Amazon EC2 console once they are created.

encrypted -> (boolean)

Indicates whether the volume should be encrypted. If no value is specified, encryption is turned on by default. This parameter maps 1:1 with the Encrypted parameter of the CreateVolume API in the Amazon EC2 API Reference .

kmsKeyId -> (string)

The Amazon Resource Name (ARN) identifier of the Amazon Web Services Key Management Service key to use for Amazon EBS encryption. When encryption is turned on and no Amazon Web Services Key Management Service key is specified, the default Amazon Web Services managed key for Amazon EBS volumes is used. This parameter maps 1:1 with the KmsKeyId parameter of the CreateVolume API in the Amazon EC2 API Reference .

Warning
Amazon Web Services authenticates the Amazon Web Services Key Management Service key asynchronously. Therefore, if you specify an ID, alias, or ARN that is invalid, the action can appear to complete, but eventually fails.

volumeType -> (string)

The volume type. This parameter maps 1:1 with the VolumeType parameter of the CreateVolume API in the Amazon EC2 API Reference . For more information, see Amazon EBS volume types in the Amazon EC2 User Guide .

The following are the supported volume types.

iops -> (integer)

The number of I/O operations per second (IOPS). For gp3 , io1 , and io2 volumes, this represents the number of IOPS that are provisioned for the volume. For gp2 volumes, this represents the baseline performance of the volume and the rate at which the volume accumulates I/O credits for bursting.

The following are the supported values for each volume type.

gp3 : 3,000 - 16,000 IOPS

io1 : 100 - 64,000 IOPS

io2 : 100 - 256,000 IOPS

This parameter is required for io1 and io2 volume types. The default for gp3 volumes is 3,000 IOPS . This parameter is not supported for st1 , sc1 , or standard volume types.

This parameter maps 1:1 with the Iops parameter of the CreateVolume API in the Amazon EC2 API Reference .

throughput -> (integer)

The throughput to provision for a volume, in MiB/s, with a maximum of 1,000 MiB/s. This parameter maps 1:1 with the Throughput parameter of the CreateVolume API in the Amazon EC2 API Reference .

targetGroupArn -> (string)

The full Amazon Resource Name (ARN) of the target group or groups associated with the VPC Lattice configuration that the Amazon ECS tasks will be registered to.

portName -> (string)

The name of the port mapping to register in the VPC Lattice target group. This is the name of the portMapping you defined in your task definition.

roleArn -> (string)

The ARN of the IAM role that's associated with the service. It allows the Amazon ECS container agent to register container instances with an Elastic Load Balancing load balancer.

events -> (list)

The event stream for your service. A maximum of 100 of the latest events are displayed.

(structure)

The details for an event that's associated with a service.

id -> (string)

The ID string for the event.

createdAt -> (timestamp)

The Unix timestamp for the time when the event was triggered.

message -> (string)

The event message.

createdAt -> (timestamp)

The Unix timestamp for the time when the service was created.

placementConstraints -> (list)

The placement constraints for the tasks in the service.

(structure)

An object representing a constraint on task placement. For more information, see Task placement constraints in the Amazon Elastic Container Service Developer Guide .

Note
If you're using the Fargate launch type, task placement constraints aren't supported.

type -> (string)

The type of constraint. Use distinctInstance to ensure that each task in a particular group is running on a different container instance. Use memberOf to restrict the selection to a group of valid candidates.

expression -> (string)

A cluster query language expression to apply to the constraint. The expression can have a maximum length of 2000 characters. You can't specify an expression if the constraint type is distinctInstance . For more information, see Cluster query language in the Amazon Elastic Container Service Developer Guide .

placementStrategy -> (list)

The placement strategy that determines how tasks for the service are placed.

(structure)

The task placement strategy for a task or service. For more information, see Task placement strategies in the Amazon Elastic Container Service Developer Guide .

type -> (string)

The type of placement strategy. The random placement strategy randomly places tasks on available candidates. The spread placement strategy spreads placement across available candidates evenly based on the field parameter. The binpack strategy places tasks on available candidates that have the least available amount of the resource that's specified with the field parameter. For example, if you binpack on memory, a task is placed on the instance with the least amount of remaining memory but still enough to run the task.

field -> (string)

The field to apply the placement strategy against. For the spread placement strategy, valid values are instanceId (or host , which has the same effect), or any platform or custom attribute that's applied to a container instance, such as attribute:ecs.availability-zone . For the binpack placement strategy, valid values are cpu and memory . For the random placement strategy, this field is not used.

networkConfiguration -> (structure)

The VPC subnet and security group configuration for tasks that receive their own elastic network interface by using the awsvpc networking mode.

awsvpcConfiguration -> (structure)

The VPC subnets and security groups that are associated with a task.

Note
All specified subnets and security groups must be from the same VPC.

subnets -> (list)

The IDs of the subnets associated with the task or service. There's a limit of 16 subnets that can be specified per awsvpcConfiguration .

Note
All specified subnets must be from the same VPC.

(string)

securityGroups -> (list)

The IDs of the security groups associated with the task or service. If you don't specify a security group, the default security group for the VPC is used. There's a limit of 5 security groups that can be specified per awsvpcConfiguration .

Note
All specified security groups must be from the same VPC.

(string)

assignPublicIp -> (string)

Whether the task's elastic network interface receives a public IP address. The default value is ENABLED .

healthCheckGracePeriodSeconds -> (integer)

The period of time, in seconds, that the Amazon ECS service scheduler ignores unhealthy Elastic Load Balancing target health checks after a task has first started.

schedulingStrategy -> (string)

The scheduling strategy to use for the service. For more information, see Services .

There are two service scheduler strategies available.

REPLICA -The replica scheduling strategy places and maintains the desired number of tasks across your cluster. By default, the service scheduler spreads tasks across Availability Zones. You can use task placement strategies and constraints to customize task placement decisions.

DAEMON -The daemon scheduling strategy deploys exactly one task on each active container instance. This task meets all of the task placement constraints that you specify in your cluster. The service scheduler also evaluates the task placement constraints for running tasks. It stop tasks that don't meet the placement constraints.

Note
Fargate tasks don't support the DAEMON scheduling strategy.

deploymentController -> (structure)

The deployment controller type the service is using.

type -> (string)

The deployment controller type to use.

There are three deployment controller types available:

ECS

The rolling update (ECS ) deployment type involves replacing the current running version of the container with the latest version. The number of containers Amazon ECS adds or removes from the service during a rolling update is controlled by adjusting the minimum and maximum number of healthy tasks allowed during a service deployment, as specified in the DeploymentConfiguration .

For more information about rolling deployments, see Deploy Amazon ECS services by replacing tasks in the Amazon Elastic Container Service Developer Guide .

CODE_DEPLOY

The blue/green (CODE_DEPLOY ) deployment type uses the blue/green deployment model powered by CodeDeploy, which allows you to verify a new deployment of a service before sending production traffic to it.

For more information about blue/green deployments, see Validate the state of an Amazon ECS service before deployment in the Amazon Elastic Container Service Developer Guide .

EXTERNAL

The external (EXTERNAL ) deployment type enables you to use any third-party deployment controller for full control over the deployment process for an Amazon ECS service.

For more information about external deployments, see Deploy Amazon ECS services using a third-party controller in the Amazon Elastic Container Service Developer Guide .

tags -> (list)

The metadata that you apply to the service to help you categorize and organize them. Each tag consists of a key and an optional value. You define bot the key and value.

The following basic restrictions apply to tags:

Maximum number of tags per resource - 50

For each resource, each tag key must be unique, and each tag key can have only one value.

Maximum key length - 128 Unicode characters in UTF-8

Maximum value length - 256 Unicode characters in UTF-8

If your tagging schema is used across multiple services and resources, remember that other services may have restrictions on allowed characters. Generally allowed characters are: letters, numbers, and spaces representable in UTF-8, and the following characters: + - = . _ : / @.

Tag keys and values are case-sensitive.

Do not use aws: , AWS: , or any upper or lowercase combination of such as a prefix for either keys or values as it is reserved for Amazon Web Services use. You cannot edit or delete tag keys or values with this prefix. Tags with this prefix do not count against your tags per resource limit.

key -> (string)

One part of a key-value pair that make up a tag. A key is a general label that acts like a category for more specific tag values.

value -> (string)

The optional part of a key-value pair that make up a tag. A value acts as a descriptor within a tag category (key).

createdBy -> (string)

The principal that created the service.

enableECSManagedTags -> (boolean)

Determines whether to use Amazon ECS managed tags for the tasks in the service. For more information, see Tagging Your Amazon ECS Resources in the Amazon Elastic Container Service Developer Guide .

propagateTags -> (string)

Determines whether to propagate the tags from the task definition or the service to the task. If no value is specified, the tags aren't propagated.
