                   resources.

                   A Policy is a collection of bindings. A binding binds
                   one or more members to a single role. Members can be
                   user accounts, service accounts, Google groups, and
                   domains (such as G Suite). A role is a named list of
                   permissions (defined by IAM or configured by users).
                   A binding can optionally specify a condition, which
                   is a logic expression that further constrains the
                   role binding based on attributes about the request
                   and/or target resource.

                   resources.

                   A Policy is a collection of bindings. A binding binds
                   one or more members to a single role. Members can be
                   user accounts, service accounts, Google groups, and
                   domains (such as G Suite). A role is a named list of
                   permissions (defined by IAM or configured by users).
                   A binding can optionally specify a condition, which
                   is a logic expression that further constrains the
                   role binding based on attributes about the request
                   and/or target resource.
