Overview

Defines an Identity and Access Management (IAM) policy. It is used to specify access control policies for Cloud Platform 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.

JSON Example

{
  "bindings": [
    {
      "role": "roles/resourcemanager.organizationAdmin",
      "members": [
        "user:[email protected]",
        "group:[email protected]",
        "domain:google.com",
        "serviceAccount:[email protected]"
      ]
    },
    {
      "role": "roles/resourcemanager.organizationViewer",
      "members": ["user:[email protected]"],
      "condition": {
        "title": "expirable access",
        "description": "Does not grant access after Sep 2020",
        "expression": "request.time <
        timestamp('2020-10-01T00:00:00.000Z')",
      }
    }
  ]

#bindings ⇒ Array<Google::Iam::V1::Binding>

Returns Associates a list of members to a role. Optionally may specify a condition that determines when binding is in effect. bindings with no members will result in an error.

Returns:

  • (Array<Google::Iam::V1::Binding>) —

    Associates a list of members to a role. Optionally may specify a condition that determines when binding is in effect. bindings with no members will result in an error.

#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. Due to blind-set semantics of an etag-less policy, 'setIamPolicy' will not fail even if the incoming policy version does not meet the requirements for modifying the stored policy.

#version ⇒ Integer

Returns Specifies the format of the policy.

Valid values are 0, 1, and 3. Requests specifying an invalid value will be rejected.

Operations affecting conditional bindings must specify version 3. This can be either setting a conditional policy, modifying a conditional binding, or removing a binding (conditional or unconditional) from the stored conditional policy. Operations on non-conditional policies may specify any valid value or leave the field unset.

If no etag is provided in the call to setIamPolicy, version compliance checks against the stored policy is skipped.
