+    <code class="details" id="getIamPolicy">getIamPolicy(resource, x__xgafv=None)</code>
+  <pre>Gets the access control policy for a resource. Returns an empty policy if the resource exists and does not have a policy set.
+
+Args:
+  resource: string, REQUIRED: The resource for which the policy is being requested. `resource` is usually specified as a path. For example, a Project resource is specified as `projects/{project}`. (required)
+  x__xgafv: string, V1 error format.

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. **Example** { "bindings": [ { "role": "roles/owner", "members": [ "user:mike@example.com", "group:admins@example.com", "domain:google.com", "serviceAccount:my-other-app@appspot.gserviceaccount.com", ] }, { "role": "roles/viewer", "members": ["user:sean@example.com"] } ] } For a description of IAM and its features, see the [IAM developer's guide](https://cloud.google.com/iam).

For example, `alice@gmail.com` or `joe@example.com`. * `serviceAccount:{emailid}`: An email address that represents a service account. For example, `my-other-app@appspot.gserviceaccount.com`. * `group:{emailid}`: An email address that represents a Google group.

It is strongly suggested that systems make use of the `etag` in the read-modify-write cycle to perform policy updates in order to avoid race conditions: An `etag` is returned in the response to `getIamPolicy`, and systems are expected to put that etag in the request to `setIamPolicy` to ensure that their change will be applied to the same version of the policy. If no `etag` is provided in the call to `setIamPolicy`, then the existing policy is overwritten blindly.
