list_tasks

Operation

list_tasks async

list_tasks(input: ListTasksInput, plugins: list[Plugin] | None = None) -> ListTasksOutput

Returns a list of tasks. You can filter the results by cluster, task definition family, container instance, launch type, what IAM principal started the task, or by the desired status of the task.

Recently stopped tasks might appear in the returned results.

Parameters:

Name Type Description Default
input ListTasksInput

An instance of ListTasksInput.

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
ListTasksOutput

An instance of ListTasksOutput.

Input

ListTasksInput dataclass

Bases: _SerdeShape

Attributes

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

The short name or full Amazon Resource Name (ARN) of the cluster to use when filtering the ListTasks results. If you do not specify a cluster, the default cluster is assumed.

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

The container instance ID or full ARN of the container instance to use when filtering the ListTasks results. Specifying a containerInstance limits the results to tasks that belong to that container instance.

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

The name of the daemon to use when filtering the ListTasks results. Specifying a daemonName limits the results to tasks that belong to that daemon.

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

The task desired status to use when filtering the ListTasks results. Specifying a desiredStatus of STOPPED limits the results to tasks that Amazon ECS has set the desired status to STOPPED. This can be useful for debugging tasks that aren't starting properly or have died or finished. The default status filter is RUNNING, which shows tasks that Amazon ECS has set the desired status to RUNNING.

Note

Although you can filter results based on a desired status of PENDING, this doesn't return any results. Amazon ECS never sets the desired status of a task to that value (only a task's lastStatus may have a value of PENDING).

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

The name of the task definition family to use when filtering the ListTasks results. Specifying a family limits the results to tasks that belong to that family.

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

The launch type to use when filtering the ListTasks results.

max_results class-attribute instance-attribute
max_results: int | None = ...

The maximum number of task results that ListTasks returned in paginated output. When this parameter is used, ListTasks 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 ListTasks request with the returned nextToken value. This value can be between 1 and 100. If this parameter isn't used, then ListTasks returns up to 100 results and a nextToken value if applicable.

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

The nextToken value returned from a ListTasks request indicating that more results are available to fulfill the request and further calls will be needed. If maxResults was provided, it's possible the number of results to be fewer than maxResults.

Note

This token should be treated as an opaque identifier that is only used to retrieve the next items in a list and not for other programmatic purposes.

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

The name of the service to use when filtering the ListTasks results. Specifying a serviceName limits the results to tasks that belong to that service.

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

The startedBy value to filter the task results with. Specifying a startedBy value limits the results to tasks that were started with that value.

When you specify startedBy as the filter, it must be the only filter that you use.

Output

ListTasksOutput dataclass

Bases: _SerdeShape

Attributes

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

The nextToken value to include in a future ListTasks request. When the results of a ListTasks request exceed maxResults, this value can be used to retrieve the next page of results. This value is null when there are no more results to return.

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_arns class-attribute instance-attribute
task_arns: list[str] | None = ...

The list of task ARN entries for the ListTasks request.
