list_container_instances#

ECS.Client.list_container_instances(**kwargs)#

Returns a list of container instances in a specified cluster. You can filter the results of a ListContainerInstances operation with cluster query language statements inside the filter parameter. For more information, see Cluster Query Language in the Amazon Elastic Container Service Developer Guide.

Request Syntax

response = client.list_container_instances(
    cluster='string',
    filter='string',
    nextToken='string',
    maxResults=123,
    status='ACTIVE'|'DRAINING'|'REGISTERING'|'DEREGISTERING'|'REGISTRATION_FAILED'
)
Parameters:

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

  • filter (string) – You can filter the results of a ListContainerInstances operation with cluster query language statements. For more information, see Cluster Query Language in the Amazon Elastic Container Service Developer Guide.

  • nextToken (string) –

    The nextToken value returned from a ListContainerInstances request indicating that more results are available to fulfill the request and further calls are needed. If maxResults was provided, it’s possible the number of results to be fewer than maxResults.

    Note

    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.

  • maxResults (integer) – The maximum number of container instance results that ListContainerInstances returned in paginated output. When this parameter is used, ListContainerInstances 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 ListContainerInstances request with the returned nextToken value. This value can be between 1 and 100. If this parameter isn’t used, then ListContainerInstances returns up to 100 results and a nextToken value if applicable.

  • status (string) – Filters the container instances by status. For example, if you specify the DRAINING status, the results include only container instances that have been set to DRAINING using UpdateContainerInstancesState. If you don’t specify this parameter, the default is to include container instances set to all states other than INACTIVE.

Return type:

dict

    'containerInstanceArns': [
        'string',
    ],
    'nextToken': 'string'
}

Response Structure

  • (dict) –

    • containerInstanceArns (list) –

      The list of container instances with full ARN entries for each container instance associated with the specified cluster.

      • (string) –

    • nextToken (string) –

      The nextToken value to include in a future ListContainerInstances request. When the results of a ListContainerInstances 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.

Exceptions

Examples

This example lists all of your available container instances in the specified cluster in your default region.

response = client.list_container_instances(
    cluster='default',
)

print(response)
