Class 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
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; 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 - domain:google.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') - etag: BwWWja0YfJA= - version: 3 For a description of IAM and its
features, see the IAM documentation.

Properties
AuditConfigs
Specifies cloud audit logging configuration for this policy.
Declaration
[JsonProperty("auditConfigs")]
public virtual IList<AuditConfig> AuditConfigs { get; set; }
Property Value
Type | Description |
---|---|
System.Collections.Generic.IList<AuditConfig> |
Bindings
Associates a list of members
to a role
. Optionally, may specify a condition
that determines how and
when the bindings
are applied. Each of the bindings
must contain at least one member.
Declaration
[JsonProperty("bindings")]
public virtual IList<Binding> Bindings { get; set; }
Property Value
Type | Description |
---|---|
System.Collections.Generic.IList<Binding> |
ETag
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. Important:
If you use IAM Conditions, you must include the etag
field whenever you call setIamPolicy
. If you omit
this field, then IAM allows you to overwrite a version 3
policy with a version 1
policy, and all of the
conditions in the version 3
policy are lost.
Declaration
[JsonProperty("etag")]
public virtual string ETag { get; set; }
Property Value
Type | Description |
---|---|
System.String |
Version
Specifies the format of the policy. Valid values are 0
, 1
, and 3
. 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. To learn which resources support conditions in their IAM policies, see the IAM documentation.
Declaration
[JsonProperty("version")]
public virtual int? Version { get; set; }
