type cluster:

string

type overrides:

dict

param overrides:

A list of container overrides in JSON format that specify the name of a container in the specified task definition and the overrides it should receive. You can override the default command for a container (that is specified in the task definition or Docker image) with a command override. You can also override existing environment variables (that are specified in the task definition or Docker image) on a container or add new environment variables to it with an environment override.

  • containerOverrides (list) --

    One or more container overrides sent to a task.

    • (dict) --

      The overrides that should be sent to a container.

      • name (string) --

        The name of the container that receives the override.

      • command (list) --

            The value of the key value pair. For environment variables, this is the value of the environment variable.

type count:

integer

param count:

The number of instantiations of the specified task to place on your cluster.

type startedBy:

string

param startedBy:

An optional tag specified when a task is started. For example if you automatically trigger a task to run a batch process job, you could apply a unique identifier for that job to your task with the startedBy parameter. You can then identify which tasks belong to that job by filtering the results of a ListTasks call with the startedBy value.

If a task is started by an Amazon ECS service, then the startedBy parameter contains the deployment ID of the service that starts it.

param overrides:

A list of container overrides in JSON format that specify the name of a container in the specified task definition and the overrides it should receive. You can override the default command for a container (that is specified in the task definition or Docker image) with a command override. You can also override existing environment variables (that are specified in the task definition or Docker image) on a container or add new environment variables to it with an environment override.

  • containerOverrides (list) --

    One or more container overrides sent to a task.

    • (dict) --

      The overrides that should be sent to a container.

      • name (string) --

        The name of the container that receives the override.

      • command (list) --

        The command to send to the container that overrides the default command from the Docker image or the task definition.

        • (string) --

      • environment (list) --

        The environment variables to send to the container. You can add new environment variables, which are added to the container at launch, or you can override the existing environment variables from the Docker image or the task definition.

        • (dict) --

          A key and value pair object.

          • name (string) --

            The name of the key value pair. For environment variables, this is the name of the environment variable.

            The value of the key value pair. For environment variables, this is the value of the environment variable.

type containerInstances:

list

param containerInstances:

[REQUIRED]

The container instance IDs or full Amazon Resource Name (ARN) entries for the container instances on which you would like to place your task.

  • (string) --

type startedBy:

string

param startedBy:

An optional tag specified when a task is started. For example if you automatically trigger a task to run a batch process job, you could apply a unique identifier for that job to your task with the startedBy parameter. You can then identify which tasks belong to that job by filtering the results of a ListTasks call with the startedBy value.

If a task is started by an Amazon ECS service, then the startedBy parameter contains the deployment ID of the service that starts it.

Stops a running task.

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