Configure GCP GKE Backup Restore Plan IAM Bindings

The gcp:gkebackup/restorePlanIamBinding:RestorePlanIamBinding resource, part of the Pulumi GCP provider, manages IAM role bindings for GKE Backup RestorePlans. This guide focuses on two capabilities: authoritative role-to-members binding and non-authoritative member addition.

IAM bindings reference existing RestorePlan resources and require project and location identifiers. The examples are intentionally small. Combine them with your own RestorePlan resources and identity management workflows.

Grant a role to multiple members

Teams managing restore plans often need to grant the same role to multiple users or service accounts at once, such as giving viewer access to an operations team.

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

const binding = new gcp.gkebackup.RestorePlanIamBinding("binding", {
    project: allNs.project,
    location: allNs.location,
    name: allNs.name,
    role: "roles/viewer",
    members: ["user:jane@example.com"],
});

import pulumi
import pulumi_gcp as gcp

binding = gcp.gkebackup.RestorePlanIamBinding("binding",
    project=all_ns["project"],
    location=all_ns["location"],
    name=all_ns["name"],
    role="roles/viewer",
    members=["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.NewRestorePlanIamBinding(ctx, "binding", &gkebackup.RestorePlanIamBindingArgs{
			Project:  pulumi.Any(allNs.Project),
			Location: pulumi.Any(allNs.Location),
			Name:     pulumi.Any(allNs.Name),
			Role:     pulumi.String("roles/viewer"),
			Members: pulumi.StringArray{
				pulumi.String("user:jane@example.com"),
			},
		})
		if err != nil {
			return err
		}
		return nil
	})
}

return await Deployment.RunAsync(() => 
{
    var binding = new Gcp.GkeBackup.RestorePlanIamBinding("binding", new()
    {
        Project = allNs.Project,
        Location = allNs.Location,
        Name = allNs.Name,
        Role = "roles/viewer",
        Members = new[]
        {
            "user:jane@example.com",
        },
    });

    properties:

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

The RestorePlanIamBinding resource is authoritative for the specified role: it replaces all members for that role while preserving other roles on the RestorePlan. The members array accepts user accounts, service accounts, groups, and domain identities. The project, location, and name properties identify which RestorePlan to bind the role to.

Add a single member to a role

When onboarding individual users or granting access to specific service accounts, teams add members one at a time without affecting existing 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")

		})
		if err != nil {
			return err
		}
		return nil
	})
}

        Project = allNs.Project,

        Name = allNs.Name,
        Role = "roles/viewer",
        Member = "user:jane@example.com",
    });

The RestorePlanIamMember resource is non-authoritative: it adds one member to a role without removing other members already assigned to that role. Use this when you need to grant access incrementally, such as onboarding new team members. The member property accepts the same identity formats as the members array in RestorePlanIamBinding.

Beyond these examples

These snippets focus on specific IAM binding features: role-based access control and authoritative vs non-authoritative member management. They’re intentionally minimal rather than full access control configurations.

The examples reference pre-existing infrastructure such as GKE Backup RestorePlan resources and a GCP project with configured location. They focus on configuring IAM bindings rather than provisioning the underlying backup infrastructure.

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

Conditional IAM bindings (condition property)
Full policy replacement (RestorePlanIamPolicy)
Custom role definitions
Federated identity configuration

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

Frequently Asked Questions

Resource Selection & Conflicts

What's the difference between RestorePlanIamPolicy, RestorePlanIamBinding, and RestorePlanIamMember?

RestorePlanIamPolicy is authoritative and replaces the entire IAM policy. RestorePlanIamBinding is authoritative for a given role, granting it to a list of members while preserving other roles. RestorePlanIamMember is non-authoritative, adding a single member to a role while preserving other members.

Can I use RestorePlanIamPolicy with RestorePlanIamBinding or RestorePlanIamMember?

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

Can I use RestorePlanIamBinding with RestorePlanIamMember?

Yes, but only if they don’t grant privilege to the same role. Using both for the same role causes conflicts.

IAM Configuration

What format do custom roles need?

Custom roles must use the format [projects|organizations]/{parent-name}/roles/{role-name}, for example projects/my-project/roles/my-custom-role.

What member identity formats are supported?

You can use allUsers, allAuthenticatedUsers, user:{emailid}, serviceAccount:{emailid}, group:{emailid}, domain:{domain}, projectOwner:projectid, projectEditor:projectid, projectViewer:projectid, or federated identities like principal://iam.googleapis.com/locations/global/workforcePools/example-contractors/subject/joe@example.com.

Which properties are immutable after creation?

The location, name, project, role, and condition properties cannot be changed after creation.

Import & Custom Roles

How do I import a RestorePlan IAM resource with a custom role?

Use the full custom role name in the import command, for example projects/my-project/roles/my-custom-role or organizations/my-org/roles/my-custom-role.
