     * Defines an Identity and Access Management (IAM) policy. It is used to specify access control policies for Cloud Platform resources.   A `Policy` consists of a list of `bindings`. A `binding` binds a list of `members` to a `role`, where the members can be user accounts, Google groups, Google domains, and service accounts. A `role` is a named list of permissions defined by IAM.  **JSON Example**      {       &quot;bindings&quot;: [         {           &quot;role&quot;: &quot;roles/owner&quot;,           &quot;members&quot;: [             &quot;user:mike@example.com&quot;,             &quot;group:admins@example.com&quot;,             &quot;domain:google.com&quot;,             &quot;serviceAccount:my-other-app@appspot.gserviceaccount.com&quot;           ]         },         {           &quot;role&quot;: &quot;roles/viewer&quot;,           &quot;members&quot;: [&quot;user:sean@example.com&quot;]         }       ]     }  **YAML Example**      bindings:     - members:       - user:mike@example.com       - group:admins@example.com       - domain:google.com       - serviceAccount:my-other-app@appspot.gserviceaccount.com       role: roles/owner     - members:       - user:sean@example.com       role: roles/viewer   For a description of IAM and its features, see the [IAM developer&#39;s guide](https://cloud.google.com/iam/docs).
