Manage GCP GKE Backup Restore Plan IAM Access

The gcp:gkebackup/restorePlanIamMember:RestorePlanIamMember resource, part of the Pulumi GCP provider, manages IAM permissions for GKE backup restore plans by adding individual members to roles without affecting other role assignments. This guide focuses on three approaches: adding single members, binding multiple members, and replacing entire policies.

These resources reference existing restore plans and have compatibility constraints. RestorePlanIamPolicy cannot be used with RestorePlanIamBinding or RestorePlanIamMember. RestorePlanIamBinding and RestorePlanIamMember can coexist only if they manage different roles. The examples are intentionally small. Combine them with your own restore plan infrastructure and access control requirements.

Grant a role to a single member

When you need to give specific permissions to one user or service account, RestorePlanIamMember adds them without changing other role assignments.

import * as pulumi from "@pulumi/pulumi";
import * as gcp from "@pulumi/gcp";

const member = new gcp.gkebackup.RestorePlanIamMember("member", {
    project: allNs.project,
    location: allNs.location,
    name: allNs.name,
    role: "roles/viewer",
    member: "user:jane@example.com",
});

import pulumi
import pulumi_gcp as gcp

member = gcp.gkebackup.RestorePlanIamMember("member",
    project=all_ns["project"],
    location=all_ns["location"],
    name=all_ns["name"],
    role="roles/viewer",
    member="user:jane@example.com")

package main

import (
	"github.com/pulumi/pulumi-gcp/sdk/v9/go/gcp/gkebackup"
	"github.com/pulumi/pulumi/sdk/v3/go/pulumi"
)

func main() {
	pulumi.Run(func(ctx *pulumi.Context) error {
		_, err := gkebackup.NewRestorePlanIamMember(ctx, "member", &gkebackup.RestorePlanIamMemberArgs{
			Project:  pulumi.Any(allNs.Project),
			Location: pulumi.Any(allNs.Location),
			Name:     pulumi.Any(allNs.Name),
			Role:     pulumi.String("roles/viewer"),
			Member:   pulumi.String("user:jane@example.com"),
		})
		if err != nil {
			return err
		}
		return nil
	})
}

using Gcp = Pulumi.Gcp;

return await Deployment.RunAsync(() =>

    var member = new Gcp.GkeBackup.RestorePlanIamMember("member", new()

        Project = allNs.Project,

        Name = allNs.Name,

      name: ${allNs.name}
      role: roles/viewer
      member: user:jane@example.com

The member property identifies who receives access using formats like “user:jane@example.com” or “serviceAccount:app@project.iam.gserviceaccount.com”. The role property specifies the permission level. This resource is non-authoritative: it adds the member to the role while preserving other members already assigned to that role.

Grant a role to multiple members at once

When several users or service accounts need identical permissions, RestorePlanIamBinding assigns them as a group.

      role: roles/viewer
      members:
        - user:jane@example.com

The members property takes a list of identifiers. RestorePlanIamBinding is authoritative for the specified role: it replaces all members for that role but leaves other roles untouched. If you later add another RestorePlanIamBinding for the same role, they will conflict.

Replace the entire IAM policy

Organizations with strict access requirements can define the complete IAM policy from scratch using RestorePlanIamPolicy.

import * as pulumi from "@pulumi/pulumi";
import * as gcp from "@pulumi/gcp";

const admin = gcp.organizations.getIAMPolicy({
    bindings: [{
        role: "roles/viewer",
        members: ["user:jane@example.com"],

    project: allNs.project,

});

func main() {

		admin, err := organizations.LookupIAMPolicy(ctx, &organizations.LookupIAMPolicyArgs{
			Bindings: []organizations.GetIAMPolicyBinding{

					Role: "roles/viewer",

		if err != nil {

		_, err = gkebackup.NewRestorePlanIamPolicy(ctx, "policy", &gkebackup.RestorePlanIamPolicyArgs{
			Project:    pulumi.Any(allNs.Project),

The policyData property contains the full policy definition, typically constructed using getIAMPolicy. RestorePlanIamPolicy is fully authoritative: it replaces the entire IAM policy for the restore plan. This approach cannot coexist with RestorePlanIamBinding or RestorePlanIamMember because they would compete to control the policy.

Beyond these examples

These snippets focus on specific IAM management approaches: incremental member and binding management, and authoritative policy replacement. They’re intentionally minimal rather than complete access control solutions.

The examples reference pre-existing infrastructure such as GKE backup restore plans identified by project, location, and name. They focus on IAM configuration rather than provisioning the restore plans themselves.

To keep things focused, common IAM patterns are omitted, including:

Conditional IAM bindings (condition property)
Custom role definitions and formatting
Policy conflict resolution between resource types
Federated identity configuration

These omissions are intentional: the goal is to illustrate how each IAM resource type is wired, not provide drop-in access control modules. See the RestorePlanIamMember resource reference for all available configuration options.

Frequently Asked Questions

Resource Selection & Conflicts

What's the difference between RestorePlanIamPolicy, IamBinding, and IamMember?

RestorePlanIamPolicy is authoritative and replaces the entire IAM policy. RestorePlanIamBinding is authoritative for a specific role, replacing all members for that role while preserving other roles. RestorePlanIamMember is non-authoritative, adding a single member to a role without affecting other members.

Can I use RestorePlanIamPolicy with IamBinding or IamMember?

No, RestorePlanIamPolicy cannot be used with RestorePlanIamBinding or RestorePlanIamMember because they will conflict over the policy state.

Can I use RestorePlanIamBinding and IamMember together?

Yes, but only if they grant different roles. Using both for the same role will cause conflicts.

Identity & Role Configuration

What identity formats can I use for the member parameter?

You can use allUsers, allAuthenticatedUsers, user:{email}, serviceAccount:{email}, group:{email}, domain:{domain}, projectOwner/Editor/Viewer:{projectid}, or federated identities (e.g., principal://iam.googleapis.com/...).

How do I specify a custom role?

Custom roles must use the format [projects|organizations]/{parent-name}/roles/{role-name} (e.g., projects/my-project/roles/my-custom-role).

Common Use Cases

How do I grant a role to a single user?

Use RestorePlanIamMember with member set to user:{email} (e.g., user:jane@example.com) and specify the desired role.

How do I grant a role to multiple users at once?

Use RestorePlanIamBinding with a members array containing all user identities and specify the role to grant.
