 * An Identity and Access Management (IAM) policy, which specifies access

 * 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":
