IAMPolicy

API Overview

Manages Identity and Access Management (IAM) policies.

Any implementation of an API that offers access control features implements the google.iam.v1.IAMPolicy interface.

Data model

Access control is applied when a principal (user or service account), takes some action on a resource exposed by a service. Resources, identified by URI-like names, are the unit of access control specification. Service implementations can choose the granularity of access control and the supported permissions for their resources. For example one database service may allow access control to be specified only at the Table level, whereas another might allow access control to also be specified at the Column level.

Policy Structure

See google.iam.v1.Policy

This is intentionally not a CRUD style API because access control policies are created and deleted implicitly with the resources to which they are attached.

GetIamPolicy

rpc GetIamPolicy(GetIamPolicyRequest) returns (Policy)

Gets the access control policy for a resource. Returns an empty policy if the resource exists and does not have a policy set.

Authorization scopes

Requires the following OAuth scope:

  • https://www.googleapis.com/auth/cloud-platform

For more information, see the Authentication Overview.

SetIamPolicy

rpc SetIamPolicy(SetIamPolicyRequest) returns (Policy)

Sets the access control policy on the specified resource. Replaces any existing policy.

Can return NOT_FOUND, INVALID_ARGUMENT, and PERMISSION_DENIED errors.

Authorization scopes

Requires the following OAuth scope:

  • https://www.googleapis.com/auth/cloud-platform

For more information, see the Authentication Overview.

TestIamPermissions

rpc TestIamPermissions(TestIamPermissionsRequest) returns (TestIamPermissionsResponse)

Returns permissions that a caller has on the specified resource. If the resource does not exist, this will return an empty set of permissions, not a NOT_FOUND error.

Note: This operation is designed to be used for building permission-aware UIs and command-line tools, not for authorization checking. This operation may "fail open" without warning.

Binding

Associates members, or principals, with a role.

Fields
role

string

Role that is assigned to the list of members, or principals. For example, roles/viewer, roles/editor, or roles/owner.

For an overview of the IAM roles and permissions, see the IAM documentation. For a list of the available pre-defined roles, see here.

members[]

string

Specifies the principals requesting access for a Google Cloud resource. members can have the following values:

  • allUsers: A special identifier that represents anyone who is on the internet; with or without a Google account.

  • allAuthenticatedUsers: A special identifier that represents anyone who is authenticated with a Google account or a service account. Does not include identities that come from external identity providers (IdPs) through identity federation.

  • user:{emailid}: An email address that represents a specific Google account. For example, alice@example.com .

  • serviceAccount:{emailid}: An email address that represents a Google service account. For example, my-other-app@appspot.gserviceaccount.com.

  • serviceAccount:{projectid}.svc.id.goog[{namespace}/{kubernetes-sa}]: An identifier for a Kubernetes service account. For example, my-project.svc.id.goog[my-namespace/my-kubernetes-sa].

  • group:{emailid}: An email address that represents a Google group. For example, admins@example.com.

  • domain:{domain}: The G Suite domain (primary) that represents all the users of that domain. For example, google.com or example.com.
  • principal://iam.googleapis.com/locations/global/workforcePools/{pool_id}/subject/{subject_attribute_value}: A single identity in a workforce identity pool.

  • principalSet://iam.googleapis.com/locations/global/workforcePools/{pool_id}/group/{group_id}: All workforce identities in a group.

  • principalSet://iam.googleapis.com/locations/global/workforcePools/{pool_id}/attribute.{attribute_name}/{attribute_value}: All workforce identities with a specific attribute value.

  • principalSet://iam.googleapis.com/locations/global/workforcePools/{pool_id}/*: All identities in a workforce identity pool.

  • principal://iam.googleapis.com/projects/{project_number}/locations/global/workloadIdentityPools/{pool_id}/subject/{subject_attribute_value}: A single identity in a workload identity pool.

  • principalSet://iam.googleapis.com/projects/{project_number}/locations/global/workloadIdentityPools/{pool_id}/group/{group_id}: A workload identity pool group.

  • principalSet://iam.googleapis.com/projects/{project_number}/locations/global/workloadIdentityPools/{pool_id}/attribute.{attribute_name}/{attribute_value}: All identities in a workload identity pool with a certain attribute.

  • principalSet://iam.googleapis.com/projects/{project_number}/locations/global/workloadIdentityPools/{pool_id}/*: All identities in a workload identity pool.

  • deleted:user:{emailid}?uid={uniqueid}: An email address (plus unique identifier) representing a user that has been recently deleted. For example, alice@example.com?uid=123456789012345678901. If the user is recovered, this value reverts to user:{emailid} and the recovered user retains the role in the binding.

  • deleted:serviceAccount:{emailid}?uid={uniqueid}: An email address (plus unique identifier) representing a service account that has been recently deleted. For example, my-other-app@appspot.gserviceaccount.com?uid=123456789012345678901. If the service account is undeleted, this value reverts to serviceAccount:{emailid} and the undeleted service account retains the role in the binding.

  • deleted:group:{emailid}?uid={uniqueid}: An email address (plus unique identifier) representing a Google group that has been recently deleted. For example, admins@example.com?uid=123456789012345678901. If the group is recovered, this value reverts to group:{emailid} and the recovered group retains the role in the binding.

  • deleted:principal://iam.googleapis.com/locations/global/workforcePools/{pool_id}/subject/{subject_attribute_value}: Deleted single identity in a workforce identity pool. For example, deleted:principal://iam.googleapis.com/locations/global/workforcePools/my-pool-id/subject/my-subject-attribute-value.

GetIamPolicyRequest

Request message for GetIamPolicy method.

Fields
resource

string

REQUIRED: The resource for which the policy is being requested. See Resource names for the appropriate value for this field.

options

GetPolicyOptions

OPTIONAL: A GetPolicyOptions object for specifying options to GetIamPolicy.

GetPolicyOptions

Encapsulates settings provided to GetIamPolicy.

Fields
requested_policy_version

int32

Optional. The maximum policy version that will be used to format the policy.

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

Requests for policies with any conditional role bindings must specify version 3. Policies with no conditional role bindings may specify any valid value or leave the field unset.

The policy in the response might use the policy version that you specified, or it might use a lower policy version. For example, if you specify version 3, but the policy has no conditional role bindings, the response uses version 1.

To learn which resources support conditions in their IAM policies, see the IAM documentation.

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
      - 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.

Fields
version

int32

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 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.

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.

bindings[]

Binding

Associates a list of members, or principals, with 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 principal.

The bindings in a Policy 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 the bindings grant 50 different roles to user:alice@example.com, and not to any other principal, then you can add another 1,450 principals to the bindings in the Policy.

etag

bytes

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.

SetIamPolicyRequest

Request message for SetIamPolicy method.

Fields
resource

string

REQUIRED: The resource for which the policy is being specified. See Resource names for the appropriate value for this field.

policy

Policy

REQUIRED: The complete policy to be applied to the resource. The size of the policy is limited to a few 10s of KB. An empty policy is a valid policy but certain Google Cloud services (such as Projects) might reject them.

TestIamPermissionsRequest

Request message for TestIamPermissions method.

Fields
resource

string

REQUIRED: The resource for which the policy detail is being requested. See Resource names for the appropriate value for this field.

permissions[]

string

The set of permissions to check for the resource. Permissions with wildcards (such as * or storage.*) are not allowed. For more information see IAM Overview.

TestIamPermissionsResponse

Response message for TestIamPermissions method.

Fields
permissions[]

string

A subset of TestPermissionsRequest.permissions that the caller is allowed.
