Network.AWS.ECS.ListTasks

Returns a list of tasks for a specified cluster. You can filter the results by family name, by a particular container instance, or by the desired status of the task with the family, containerInstance, and desiredStatus parameters.

See: AWS API Reference for ListTasks.

This operation returns paginated results.

Creating a Request

listTasks :: ListTasks

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

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

• ltDesiredStatus
• ltCluster
• ltFamily
• ltNextToken
• ltStartedBy
• ltServiceName
• ltContainerInstance
• ltMaxResults

data ListTasks

See: listTasks smart constructor.

Request Lenses

ltDesiredStatus :: Lens' ListTasks (Maybe DesiredStatus)

The task status that you want to filter the ListTasks results with. Specifying a desiredStatus of STOPPED will limit the results to tasks that are in the STOPPED status, which can be useful for debugging tasks that are not starting properly or have died or finished. The default status filter is RUNNING.

ltCluster :: Lens' ListTasks (Maybe Text)

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

ltFamily :: Lens' ListTasks (Maybe Text)

The name of the family that you want to filter the ListTasks results with. Specifying a family will limit the results to tasks that belong to that family.

ltNextToken :: Lens' ListTasks (Maybe Text)

The nextToken value returned from a previous paginated ListTasks request where maxResults was used and the results exceeded the value of that parameter. Pagination continues from the end of the previous results that returned the nextToken value. This value is null when there are no more results to return.

ltStartedBy :: Lens' ListTasks (Maybe Text)

The startedBy value that you want to filter the task results with. Specifying a startedBy value will limit the results to tasks that were started with that value.

ltServiceName :: Lens' ListTasks (Maybe Text)

The name of the service that you want to filter the ListTasks results with. Specifying a serviceName will limit the results to tasks that belong to that service.

ltContainerInstance :: Lens' ListTasks (Maybe Text)

The container instance UUID or full Amazon Resource Name (ARN) of the container instance that you want to filter the ListTasks results with. Specifying a containerInstance will limit the results to tasks that belong to that container instance.

ltMaxResults :: Lens' ListTasks (Maybe Int)

The maximum number of task results returned by ListTasks 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 is not used, then ListTasks returns up to 100 results and a nextToken value if applicable.

Response Lenses

ltrsNextToken :: Lens' ListTasksResponse (Maybe Text)

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.

ltrsTaskARNs :: Lens' ListTasksResponse [Text]

The list of task Amazon Resource Name (ARN) entries for the ListTasks request.

ltrsResponseStatus :: Lens' ListTasksResponse Int

The response status code.
