Overview
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
"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"]
]
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's guide.

#etag ⇒ String
etag
is used for optimistic concurrency control as a way to help
prevent simultaneous updates of a policy from overwriting each other.
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.
