Amazonka.ECS.ListTaskDefinitions
Description
Returns a list of task definitions that are registered to your account.
You can filter the results by family name with the familyPrefix
parameter or by status with the status parameter.
This operation returns paginated results.

newListTaskDefinitions :: ListTaskDefinitions Source #
Create a value of ListTaskDefinitions with all optional fields omitted.
Use generic-lens or optics to modify other optional fields.
The following record fields are available, with the corresponding lenses provided for backwards compatibility:
$sel:status:ListTaskDefinitions', listTaskDefinitions_status - The task definition status with which to filter the
ListTaskDefinitions results. By default, only ACTIVE task
definitions are listed. By setting this parameter to INACTIVE, you can
view task definitions that are INACTIVE as long as an active task or
service still references them. If you paginate the resulting output, be
sure to keep the status value constant in each subsequent request.
$sel:familyPrefix:ListTaskDefinitions', listTaskDefinitions_familyPrefix - The full family name with which to filter the ListTaskDefinitions
results. Specifying a familyPrefix limits the listed task definitions
to task definition revisions that belong to that family.
$sel:nextToken:ListTaskDefinitions', listTaskDefinitions_nextToken - The nextToken value returned from a ListTaskDefinitions request
indicating that more results are available to fulfill the request and
further calls will be needed. If maxResults was provided, it is
possible the number of results to be fewer than maxResults.
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.
$sel:sort:ListTaskDefinitions', listTaskDefinitions_sort - The order in which to sort the results. Valid values are ASC and
DESC. By default (ASC), task definitions are listed
lexicographically by family name and in ascending numerical order by
revision so that the newest task definitions in a family are listed
last. Setting this parameter to DESC reverses the sort order on family
name and revision so that the newest task definitions in a family are
listed first.
$sel:maxResults:ListTaskDefinitions', listTaskDefinitions_maxResults - The maximum number of task definition results returned by
ListTaskDefinitions 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 ListTaskDefinitions
request with the returned nextToken value. This value can be between 1
and 100. If this parameter is not used, then ListTaskDefinitions
returns up to 100 results and a nextToken value if applicable.

ListTaskDefinitions only returns maxResults results in a single page
along with a nextToken response element. The remaining results of the

The following record fields are available, with the corresponding lenses provided for backwards compatibility:
$sel:taskDefinitionArns:ListTaskDefinitionsResponse', listTaskDefinitionsResponse_taskDefinitionArns - The list of task definition Amazon Resource Name (ARN) entries for the
ListTaskDefinitions request.
$sel:nextToken:ListTaskDefinitions', listTaskDefinitionsResponse_nextToken - The nextToken value to include in a future ListTaskDefinitions
request. When the results of a ListTaskDefinitions 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.
$sel:httpStatus:ListTaskDefinitionsResponse', listTaskDefinitionsResponse_httpStatus - The response's http status code.
