Amazon EC2 Container Service

{'status': 'ACTIVE | INACTIVE | ALL'}

Returns a list of task definition families that are registered to your account (which may include task definition families that no longer have any ACTIVE task definition revisions).

You can filter out task definition families that do not contain any ACTIVE task definition revisions by setting the status parameter to ACTIVE . You can also filter the results with the familyPrefix parameter.

Request Syntax

client.list_task_definition_families(
    familyPrefix='string',
    status='ACTIVE'|'INACTIVE'|'ALL',
    nextToken='string',
    maxResults=123
)

type familyPrefix

string

param familyPrefix

The familyPrefix is a string that is used to filter the results of ListTaskDefinitionFamilies . If you specify a familyPrefix , only task definition family names that begin with the familyPrefix string are returned.

type status

string

param status

The task definition family status with which to filter the ListTaskDefinitionFamilies results. By default, both ACTIVE and INACTIVE task definition families are listed. If this parameter is set to ACTIVE , only task definition families that have an ACTIVE task definition revision are returned. If this parameter is set to INACTIVE , only task definition families that do not have any ACTIVE task definition revisions are returned. If you paginate the resulting output, be sure to keep the status value constant in each subsequent request.

type nextToken

string

param nextToken

The nextToken value returned from a previous paginated ListTaskDefinitionFamilies 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.

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.

type maxResults

integer

param maxResults

The maximum number of task definition family results returned by ListTaskDefinitionFamilies in paginated output. When this parameter is used, ListTaskDefinitions 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 ListTaskDefinitionFamilies request with the returned nextToken value. This value can be between 1 and 100. If this parameter is not used, then ListTaskDefinitionFamilies returns up to 100 results and a nextToken value if applicable.
