Network.AWS.ECS.RunTask

Contents

Description

Start a task using random placement and the default Amazon ECS scheduler. If you want to use your own scheduler or place a task on a specific container instance, use StartTask instead.

The count parameter is limited to 10 tasks per call.

See: AWS API Reference for RunTask.

Synopsis

Creating a Request

runTask Source

Creates a value of RunTask with the minimum fields required to make a request.

Use one of the following lenses to modify other fields as desired:

Request Lenses

rtOverrides :: Lens' RunTask (Maybe TaskOverride) Source

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.

A total of 8192 characters are allowed for overrides. This limit includes the JSON formatting characters of the override structure.

rtCluster :: Lens' RunTask (Maybe Text) Source

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

rtCount :: Lens' RunTask (Maybe Int) Source

The number of instantiations of the specified task that you would like to place on your cluster.

The count parameter is limited to 10 tasks per call.

rtStartedBy :: Lens' RunTask (Maybe Text) Source

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.

rtTaskDefinition :: Lens' RunTask Text Source

The family and revision ('family:revision') or full Amazon Resource Name (ARN) of the task definition that you want to run. If a revision is not specified, the latest ACTIVE revision is used.

Destructuring the Response

runTaskResponse Source

Creates a value of RunTaskResponse with the minimum fields required to make a request.

Use one of the following lenses to modify other fields as desired:

Response Lenses

rtrsFailures :: Lens' RunTaskResponse [Failure] Source

Any failed tasks from your RunTask action are listed here.

rtrsTasks :: Lens' RunTaskResponse [Task] Source

A full description of the tasks that were run. Each task that was successfully placed on your cluster will be described here.

rtrsStatus :: Lens' RunTaskResponse Int Source

The response status code.
