        # ==== Parameters
        # * cluster <~String> - short name or full Amazon Resource Name (ARN) of the cluster that hosts the container instances you want to list.
        # * maxResults <~Integer> - maximum number of container instance results returned by ListContainerInstances in paginated output.
        # * nextToken <~String> - nextToken value returned from a previous paginated ListContainerInstances request where maxResults was used.
        # ==== Returns
        # * response<~Excon::Response>:
        #   * body<~Hash>:
        #     * 'ContainerInstanceArns' <~Array> - list of container instance full ARN entries for each container instance associated with the specified cluster.
        #     * 'NextToken' <~String> - nextToken value to include in a future ListContainerInstances request.
