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.
Example
{
"bindings": [
{
"role": "roles/owner",
"members": [
"user:[email protected]",
"group:[email protected]",
"domain:google.com",
"serviceAccount:[email protected]",
]
},
{
"role": "roles/viewer",
"members": ["user:[email protected]"]
}
]
}
For a description of IAM and its features, see the IAM developer’s guide.

#etag ⇒ String
Returns 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.
