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.
Recently-stopped tasks might appear in the returned results. Currently, stopped tasks appear in the returned results for at least one hour.
This operation returns paginated results.

Creating a Request
listTasks :: ListTasks Source #
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:
See: listTasks
smart constructor.
Request Lenses
ltDesiredStatus :: Lens' ListTasks (Maybe DesiredStatus) Source #
The task desired status with which to filter the ListTasks
results. Specifying a desiredStatus
of STOPPED
limits the results to tasks that ECS has set the desired status to STOPPED
, which can be useful for debugging tasks that are not starting properly or have died or finished. The default status filter is RUNNING
, which shows tasks that ECS has set the desired status to RUNNING
.
Although you can filter results based on a desired status of PENDING
, this will not return any results because ECS never sets the desired status of a task to that value (only a task's lastStatus
may have a value of PENDING
).
ltCluster :: Lens' ListTasks (Maybe Text) Source #
The short name or full Amazon Resource Name (ARN) of the cluster that hosts the tasks to list. If you do not specify a cluster, the default cluster is assumed..
ltFamily :: Lens' ListTasks (Maybe Text) Source #
The name of the family with which to filter the ListTasks
results. Specifying a family
limits the results to tasks that belong to that family.
ltNextToken :: Lens' ListTasks (Maybe Text) Source #
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.
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.
ltStartedBy :: Lens' ListTasks (Maybe Text) Source #
The startedBy
value with which to filter the task results. Specifying a startedBy
value limits the results to tasks that were started with that value.
ltServiceName :: Lens' ListTasks (Maybe Text) Source #
The name of the service with which to filter the ListTasks
results. Specifying a serviceName
limits the results to tasks that belong to that service.
ltContainerInstance :: Lens' ListTasks (Maybe Text) Source #
The container instance ID or full Amazon Resource Name (ARN) of the container instance with which to filter the ListTasks
results. Specifying a containerInstance
limits the results to tasks that belong to that container instance.
ltMaxResults :: Lens' ListTasks (Maybe Int) Source #
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.
Destructuring the Response
Creates a value of ListTasksResponse
with the minimum fields required to make a request.
Use one of the following lenses to modify other fields as desired:
data ListTasksResponse Source #
See: listTasksResponse
smart constructor.
Response Lenses
ltrsTaskARNs :: Lens' ListTasksResponse [Text] Source #
The list of task Amazon Resource Name (ARN) entries for the ListTasks
request.
ltrsResponseStatus :: Lens' ListTasksResponse Int Source #
The response status code.
