+
+                   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).

+                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).

+
+                   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,

+                   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

+
+                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

+                    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>`__.
