create_task_set

Operation

create_task_set async

create_task_set(input: CreateTaskSetInput, plugins: list[Plugin] | None = None) -> CreateTaskSetOutput

Create a task set in the specified cluster and service. This is used when a service uses the EXTERNAL deployment controller type. For more information, see Amazon ECS deployment types in the Amazon Elastic Container Service Developer Guide.

Note

On March 21, 2024, a change was made to resolve the task definition revision before authorization. When a task definition revision is not specified, authorization will occur using the latest revision of a task definition.

For information about the maximum number of task sets and other quotas, see Amazon ECS service quotas in the Amazon Elastic Container Service Developer Guide.

Parameters:

Name Type Description Default
input CreateTaskSetInput

An instance of CreateTaskSetInput.

required
plugins list[Plugin] | None

A list of callables that modify the configuration dynamically. Changes made by these plugins only apply for the duration of the operation execution and will not affect any other operation invocations.

None

Returns:

Type Description
CreateTaskSetOutput

An instance of CreateTaskSetOutput.

Input

CreateTaskSetInput dataclass

Bases: _SerdeShape

Dataclass for CreateTaskSetInput structure.

Attributes

capacity_provider_strategy class-attribute instance-attribute
capacity_provider_strategy: list[CapacityProviderStrategyItem] | None = ...

The capacity provider strategy to use for the task set.

A capacity provider strategy consists of one or more capacity providers along with the base and weight to assign to them. A capacity provider must be associated with the cluster to be used in a capacity provider strategy. The PutClusterCapacityProviders API is used to associate a capacity provider with a cluster. Only capacity providers with an ACTIVE or UPDATING status can be used.

If a capacityProviderStrategy is specified, the launchType parameter must be omitted. If no capacityProviderStrategy or launchType is specified, the defaultCapacityProviderStrategy for the cluster is used.

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

The PutClusterCapacityProviders API operation is used to update the list of available capacity providers for a cluster after the cluster is created.

client_token class-attribute instance-attribute
client_token: str | None = ...

An identifier that you provide to ensure the idempotency of the request. It must be unique and is case sensitive. Up to 36 ASCII characters in the range of 33-126 (inclusive) are allowed.

cluster class-attribute instance-attribute
cluster: str | None = ...

The short name or full Amazon Resource Name (ARN) of the cluster that hosts the service to create the task set in.

external_id class-attribute instance-attribute
external_id: str | None = ...

An optional non-unique tag that identifies this task set in external systems. If the task set is associated with a service discovery registry, the tasks in this task set will have the ECS_TASK_SET_EXTERNAL_ID Cloud Map attribute set to the provided value.

launch_type class-attribute instance-attribute
launch_type: str | None = ...

The launch type that new tasks in the task set uses. For more information, see Amazon ECS launch types in the Amazon Elastic Container Service Developer Guide.

If a launchType is specified, the capacityProviderStrategy parameter must be omitted.

load_balancers class-attribute instance-attribute
load_balancers: list[LoadBalancer] | None = ...

A load balancer object representing the load balancer to use with the task set. The supported load balancer types are either an Application Load Balancer or a Network Load Balancer.

network_configuration class-attribute instance-attribute
network_configuration: NetworkConfiguration | None = ...

An object representing the network configuration for a task set.

platform_version class-attribute instance-attribute
platform_version: str | None = ...

The platform version that the tasks in the task set uses. A platform version is specified only for tasks using the Fargate launch type. If one isn't specified, the LATEST platform version is used.

scale class-attribute instance-attribute
scale: Scale | None = ...

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

service class-attribute instance-attribute
service: str | None = ...

The short name or full Amazon Resource Name (ARN) of the service to create the task set in.

service_registries class-attribute instance-attribute
service_registries: list[ServiceRegistry] | None = ...

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

tags class-attribute instance-attribute
tags: list[Tag] | None = ...

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. When a service is deleted, the tags are deleted.

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.

task_definition class-attribute instance-attribute
task_definition: str | None = ...

The task definition for the tasks in the task set to use. If a revision isn't specified, the latest ACTIVE revision is used.

Output

CreateTaskSetOutput dataclass

Bases: _SerdeShape

Dataclass for CreateTaskSetOutput structure.

Attributes

response_metadata class-attribute instance-attribute
response_metadata: ResponseMetadata = ...

Metadata about the response that produced this output. Use this to recover the request identifiers a service's support team needs in order to investigate a call. Members of the metadata are individually optional.

task_set class-attribute instance-attribute
task_set: TaskSet | None = ...

Information about a set of Amazon ECS tasks in either an CodeDeploy or an EXTERNAL deployment. A task set includes details such as the desired number of tasks, how many tasks are running, and whether the task set serves production traffic.
