            # A `Policy` is a collection of `bindings`. A `binding` binds one or more
            # `members` to a single `role`. Members can be user accounts, service accounts,
            # Google groups, and domains (such as G Suite). A `role` is a named list of
            # permissions; each `role` can be an IAM predefined role or a user-created
            # custom role.
            #
            # Optionally, a `binding` can specify a `condition`, which is a logical
            # expression that allows access to a resource only if the expression evaluates
            # to `true`. A condition can add constraints based on attributes of the
            # request, the resource, or both.

          # controls for Google Cloud resources.

          #
          # A `Policy` is a collection of `bindings`. A `binding` binds one or more
          # `members` to a single `role`. Members can be user accounts, service accounts,
          # Google groups, and domains (such as G Suite). A `role` is a named list of
          # permissions; each `role` can be an IAM predefined role or a user-created
          # custom role.
          #
          # Optionally, a `binding` can specify a `condition`, which is a logical
          # expression that allows access to a resource only if the expression evaluates
          # to `true`. A condition can add constraints based on attributes of the
          # request, the resource, or both.

`update(name, body=None, x__xgafv=None)`

    Updates an instance within a project. This method updates only the display

    labels, use PartialUpdateInstance.

    Args:
      name: string, Required. (`OutputOnly`)
    The unique name of the instance. Values are of the form
    `projects/{project}/instances/a-z+[a-z0-9]`. (required)
