Amazonka.ECS.ListClusters

Returns a list of existing clusters.

This operation returns paginated results.

Creating a Request

data ListClusters

See: newListClusters smart constructor.

Constructors

ListClusters'

Fields

• maxResults :: Maybe Int

  The maximum number of cluster results that ListClusters returned in paginated output. When this parameter is used, ListClusters 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 ListClusters request with the returned nextToken value. This value can be between 1 and 100. If this parameter isn't used, then ListClusters returns up to 100 results and a nextToken value if applicable.

• nextToken :: Maybe Text

  The nextToken value returned from a ListClusters 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.

  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.

newListClusters :: ListClusters

Create a value of ListClusters 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:maxResults:ListClusters', listClusters_maxResults - The maximum number of cluster results that ListClusters returned in paginated output. When this parameter is used, ListClusters 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 ListClusters request with the returned nextToken value. This value can be between 1 and 100. If this parameter isn't used, then ListClusters returns up to 100 results and a nextToken value if applicable.

ListClusters, listClusters_nextToken - The nextToken value returned from a ListClusters 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.

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.

Constructors

ListClustersResponse'

Fields

• clusterArns :: Maybe [Text]

  The list of full Amazon Resource Name (ARN) entries for each cluster that's associated with your account.

• nextToken :: Maybe Text

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

• httpStatus :: Int

  The response's http status code.
