Reference documentation and code samples for the IAM API class Google::Iam::V1::Policy.
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.
JSON example:
{
"bindings": [
{
"role": "roles/resourcemanager.organizationAdmin",
"members": [
"user:mike@example.com",
"group:admins@example.com",
"domain:google.com",
"serviceAccount:my-project-id@appspot.gserviceaccount.com"
]
},
{
"role": "roles/resourcemanager.organizationViewer",
"members": [
"user:eve@example.com"
],
"condition": {
"title": "expirable access",
"description": "Does not grant access after Sep 2020",
"expression": "request.time < timestamp('2020-10-01T00:00:00.000Z')",
}
}
],
"etag": "BwWWja0YfJA=",
"version": 3
}
YAML example:
bindings:
- members:
- user:mike@example.com
- group:admins@example.com

- serviceAccount:my-project-id@appspot.gserviceaccount.com
role: roles/resourcemanager.organizationAdmin
- members:
- user:eve@example.com
role: roles/resourcemanager.organizationViewer
condition:
title: expirable access
description: Does not grant access after Sep 2020
expression: request.time < timestamp('2020-10-01T00:00:00.000Z')

#audit_configs
def audit_configs() -> ::Array<::Google::Iam::V1::AuditConfig>
- (::Array<::Google::Iam::V1::AuditConfig>) — Specifies cloud audit logging configuration for this policy.
#audit_configs=
def audit_configs=(value) -> ::Array<::Google::Iam::V1::AuditConfig>
- value (::Array<::Google::Iam::V1::AuditConfig>) — Specifies cloud audit logging configuration for this policy.
- (::Array<::Google::Iam::V1::AuditConfig>) — Specifies cloud audit logging configuration for this policy.
#bindings
def bindings() -> ::Array<::Google::Iam::V1::Binding>
-
(::Array<::Google::Iam::V1::Binding>) — Associates a list of
members
, or principals, with arole
. Optionally, may specify acondition
that determines how and when thebindings
are applied. Each of thebindings
must contain at least one principal.The
bindings
in aPolicy
can refer to up to 1,500 principals; up to 250 of these principals can be Google groups. Each occurrence of a principal counts towards these limits. For example, if thebindings
grant 50 different roles touser:alice@example.com
, and not to any other principal, then you can add another 1,450 principals to thebindings
in thePolicy
.

#etag
def etag() -> ::String
-
(::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 theetag
in the read-modify-write cycle to perform policy updates in order to avoid race conditions: Anetag
is returned in the response togetIamPolicy
, and systems are expected to put that etag in the request tosetIamPolicy
to ensure that their change will be applied to the same version of the policy.Important: If you use IAM Conditions, you must include the
etag
field whenever you callsetIamPolicy
. If you omit this field, then IAM allows you to overwrite a version3
policy with a version1
policy, and all of the conditions in the version3
policy are lost.

#version
def version() -> ::Integer
-
(::Integer) — Specifies the format of the policy.
Valid values are
0
,1
, and3
. Requests that specify an invalid value are rejected.Any operation that affects conditional role bindings must specify version
3
. This requirement applies to the following operations:- Getting a policy that includes a conditional role binding
- Adding a conditional role binding to a policy
- Changing a conditional role binding in a policy
- Removing any role binding, with or without a condition, from a policy that includes conditions
Important: If you use IAM Conditions, you must include the
etag
field whenever you callsetIamPolicy
. If you omit this field, then IAM allows you to overwrite a version3
policy with a version1
policy, and all of the conditions in the version3
policy are lost.If a policy does not include any conditions, operations on that policy may specify any valid version or leave the field unset.
