StopTask - Amazon Elastic Container Service
Services or capabilities described in Amazon Web Services documentation might vary by Region. To see the differences applicable to the China Regions, see Getting Started with Amazon Web Services in China (PDF).

StopTask

Stops a running task. Any tags associated with the task will be deleted.

When you call StopTask on a task, the equivalent of docker stop is issued to the containers running in the task. This results in a SIGTERM value and a default 30-second timeout, after which the SIGKILL value is sent and the containers are forcibly stopped. If the container handles the SIGTERM value gracefully and exits within 30 seconds from receiving it, no SIGKILL value is sent.

For Windows containers, POSIX signals do not work and runtime stops the container by sending a CTRL_SHUTDOWN_EVENT. For more information, see Unable to react to graceful shutdown of (Windows) container #25982 on GitHub.

Note

The default 30-second timeout can be configured on the Amazon ECS container agent with the ECS_CONTAINER_STOP_TIMEOUT variable. For more information, see Amazon ECS Container Agent Configuration in the Amazon Elastic Container Service Developer Guide.

Request Syntax

Request Parameters

For information about the parameters that are common to all actions, see Common Parameters.

The request accepts the following data in JSON format.

cluster

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

Type: String

Required: No

reason

An optional message specified when a task is stopped. For example, if you're using a custom scheduler, you can use this parameter to specify the reason for stopping the task here, and the message appears in subsequent DescribeTasks> API operations on this task.

Type: String

Required: No

task

The task ID of the task to stop.

Type: String

Required: Yes

Response Elements

If the action is successful, the service sends back an HTTP 200 response.

The following data is returned in JSON format by the service.

task

The task that was stopped.

Type: Task object

Errors

For information about the errors that are common to all actions, see Common Errors.

ClientException

These errors are usually caused by a client action. This client action might be using an action or resource on behalf of a user that doesn't have permissions to use the action or resource. Or, it might be specifying an identifier that isn't valid.

The following list includes additional causes for the error:

  • The RunTask could not be processed because you use managed scaling and there is a capacity error because the quota of tasks in the PROVISIONING per cluster has been reached. For information about the service quotas, see Amazon ECS service quotas.

HTTP Status Code: 400

ClusterNotFoundException

The specified cluster wasn't found. You can view your available clusters with ListClusters. Amazon ECS clusters are Region specific.

HTTP Status Code: 400

InvalidParameterException

The specified parameter isn't valid. Review the available parameters for the API request.

HTTP Status Code: 400

ServerException

These errors are usually caused by a server issue.

HTTP Status Code: 500

Examples

In the following example or examples, the Authorization header contents (AUTHPARAMS) must be replaced with an Amazon Signature Version 4 signature. For more information, see Signature Version 4 Signing Process in the Amazon General Reference.

You only need to learn how to sign HTTP requests if you intend to create them manually. When you use the Amazon Command Line Interface or one of the Amazon SDKs to make requests to Amazon, these tools automatically sign the requests for you, with the access key that you specify when you configure the tools. When you use these tools, you don't have to sign requests yourself.

Example

This example request stops a task with the ID 1dc5c17a-422b-4dc4-b493-371970c6c4d6 in the default cluster.
