    See https://cloud.google.com/iam/docs/managing-policies for details of the
    policy file format and contents.

POSITIONAL ARGUMENTS

     represents a Cloud resource. (NOTE) Some attributes are not given
     arguments in this group but can be set in other ways.

      ◆ provide the argument instance on the command line with a fully
        specified name;
      ◆ provide the argument --project on the command line;
      ◆ set the property core/project.

     This must be specified.
