      # An Identity and Access Management (IAM) policy, which specifies access
      # controls for Google Cloud resources. A `Policy` is a collection of `bindings`.
      # A `binding` binds one or more `members`, or principals, to a single `role`.
      # Principals 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. For some types of Google
      # Cloud resources, a `binding` can also 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. To learn which resources support
      # conditions in their IAM policies, see the [IAM documentation](https://cloud.
      # google.com/iam/help/conditions/resource-policies). **JSON example:** ``` ` "
      # bindings": [ ` "role": "roles/resourcemanager.organizationAdmin", "members": [
      # "user:mike@example.com", "group:admins@example.com", "domain:google.com", "
      # serviceAccount:my-project-id@appspot.gserviceaccount.com" ] `, ` "role": "
      # roles/resourcemanager.organizationViewer", "members": [ "user:eve@example.com"
      # ], "condition": ` "title": "expirable access", "description": "Does not grant
      # access after Sep 2020", "expression": "request.time < timestamp('2020-10-01T00:
      # 00:00.000Z')", ` ` ], "etag": "BwWWja0YfJA=", "version": 3 ` ``` **YAML
      # example:** ``` bindings: - members: - user:mike@example.com - group:admins@
      # example.com - domain:google.com - serviceAccount:my-project-id@appspot.
      # gserviceaccount.com role: roles/resourcemanager.organizationAdmin - members: -
