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.

Synopsis

Creating a Request

data ListTaskDefinitions Source #

See: newListTaskDefinitions smart constructor.

Constructors

ListTaskDefinitions' 

Fields

  • familyPrefix :: Maybe Text

    The full family name to filter the ListTaskDefinitions results with. Specifying a familyPrefix limits the listed task definitions to task definition revisions that belong to that family.

  • maxResults :: Maybe Int

    The maximum number of task definition results that ListTaskDefinitions returned 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 isn't used, then ListTaskDefinitions returns up to 100 results and a nextToken value if applicable.

  • nextToken :: Maybe Text

    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.

  • sort :: Maybe SortOrder

    The order to sort the results in. 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. This is so that the newest task definitions in a family are listed first.

  • status :: Maybe TaskDefinitionStatus

    The task definition status to filter the ListTaskDefinitions results with. 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.

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:familyPrefix:ListTaskDefinitions', listTaskDefinitions_familyPrefix - The full family name to filter the ListTaskDefinitions results with. Specifying a familyPrefix limits the listed task definitions to task definition revisions that belong to that family.

$sel:maxResults:ListTaskDefinitions', listTaskDefinitions_maxResults - The maximum number of task definition results that ListTaskDefinitions returned 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 isn't used, then ListTaskDefinitions returns up to 100 results and a nextToken value if applicable.

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 to sort the results in. 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. This is so that the newest task definitions in a family are listed first.

ListTaskDefinitions, listTaskDefinitions_status - The task definition status to filter the ListTaskDefinitions results with. 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.

Constructors

ListTaskDefinitionsResponse' 

Fields

  • nextToken :: Maybe Text

    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.

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

  • httpStatus :: Int

    The response's http status code.
