Manage GCP Cloud Run Worker Pool IAM Access

The gcp:cloudrunv2/workerPoolIamMember:WorkerPoolIamMember resource, part of the Pulumi GCP provider, manages IAM permissions for Cloud Run v2 worker pools by granting roles to identities. This guide focuses on three capabilities: adding individual members to roles, managing complete member lists per role, and replacing entire IAM policies.

GCP provides three related resources for worker pool IAM: WorkerPoolIamMember (non-authoritative, adds one member), WorkerPoolIamBinding (authoritative for a role, manages all members), and WorkerPoolIamPolicy (authoritative for the entire policy, replaces everything). WorkerPoolIamPolicy cannot be used with the other two resources, as they will conflict. The examples are intentionally small. Combine them with your own worker pool references and identity management.

Grant a role to a single member

Most IAM configurations start by granting a specific role to one identity without affecting other members who already have that role.

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

const member = new gcp.cloudrunv2.WorkerPoolIamMember("member", {
    project: _default.project,
    location: _default.location,
    name: _default.name,
    role: "roles/viewer",
    member: "user:jane@example.com",
});

import pulumi
import pulumi_gcp as gcp

member = gcp.cloudrunv2.WorkerPoolIamMember("member",
    project=default["project"],
    location=default["location"],
    name=default["name"],
    role="roles/viewer",
    member="user:jane@example.com")

package main

import (
	"github.com/pulumi/pulumi-gcp/sdk/v9/go/gcp/cloudrunv2"
	"github.com/pulumi/pulumi/sdk/v3/go/pulumi"
)

func main() {
	pulumi.Run(func(ctx *pulumi.Context) error {
		_, err := cloudrunv2.NewWorkerPoolIamMember(ctx, "member", &cloudrunv2.WorkerPoolIamMemberArgs{
			Project:  pulumi.Any(_default.Project),
			Location: pulumi.Any(_default.Location),
			Name:     pulumi.Any(_default.Name),
			Role:     pulumi.String("roles/viewer"),
			Member:   pulumi.String("user:jane@example.com"),
		})
		if err != nil {
			return err
		}
		return nil
	})
}

return await Deployment.RunAsync(() => 
{
    var member = new Gcp.CloudRunV2.WorkerPoolIamMember("member", new()
    {
        Project = @default.Project,
        Location = @default.Location,
        Name = @default.Name,
        Role = "roles/viewer",
        Member = "user:jane@example.com",
    });

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

The member property specifies the identity receiving access, using formats like “user:email”, “serviceAccount:email”, or “group:email”. The role property defines the permission level. This non-authoritative approach preserves other members already assigned to the same role on the worker pool.

Grant a role to multiple members at once

When multiple identities need the same role, WorkerPoolIamBinding manages the complete member list for that role.

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

The members property lists all identities that should have this role. This resource is authoritative for the specified role: it replaces the member list for “roles/viewer” but preserves other roles on the worker pool. If you later add a WorkerPoolIamMember for the same role, they will conflict.

Replace the entire IAM policy

Some deployments require complete control over all IAM bindings, replacing any existing policy.

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

const admin = gcp.organizations.getIAMPolicy({
    bindings: [{
        role: "roles/viewer",

The policyData property accepts a complete IAM policy document, typically constructed using the getIAMPolicy data source. This resource is fully authoritative: it removes any bindings not specified in the policy. Use this approach carefully, as it can remove existing access that isn’t captured in your configuration.

Beyond these examples

These snippets focus on specific IAM management approaches: incremental member grants, role-level member management, and full policy replacement. They’re intentionally minimal rather than complete access control solutions.

The examples reference pre-existing infrastructure such as Cloud Run v2 worker pools and a GCP project with configured location. They focus on IAM configuration rather than provisioning the worker pools themselves.

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

  • Conditional IAM bindings (condition property)
  • Custom role definitions
  • Service account creation and management
  • Combining Binding and Member resources safely

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 WorkerPoolIamMember resource reference for all available configuration options.

Frequently Asked Questions

Resource Selection & Conflicts
What's the difference between WorkerPoolIamPolicy, WorkerPoolIamBinding, and WorkerPoolIamMember?
WorkerPoolIamPolicy is authoritative and replaces the entire IAM policy. WorkerPoolIamBinding is authoritative for a specific role, preserving other roles in the policy. WorkerPoolIamMember is non-authoritative and adds a single member to a role while preserving other members.
Can I use WorkerPoolIamPolicy with WorkerPoolIamBinding or WorkerPoolIamMember?
No, WorkerPoolIamPolicy cannot be used with WorkerPoolIamBinding or WorkerPoolIamMember as they will conflict over the policy. Use WorkerPoolIamPolicy alone for full control, or use WorkerPoolIamBinding and WorkerPoolIamMember together (but not for the same role).
Can I use WorkerPoolIamBinding and WorkerPoolIamMember together?
Yes, but only if they don’t grant privileges to the same role. If both resources target the same role, they will conflict.
When should I use each IAM resource type?
Use WorkerPoolIamPolicy when you need complete control over the entire policy. Use WorkerPoolIamBinding to manage all members for a specific role. Use WorkerPoolIamMember to add individual members without affecting existing members.
Identity & Role Configuration
What identity formats can I use for the member property?
You can use: allUsers, allAuthenticatedUsers, user:{email}, serviceAccount:{email}, group:{email}, domain:{domain}, projectOwner:{projectid}, projectEditor:{projectid}, projectViewer:{projectid}, or federated identities like principal://iam.googleapis.com/....
How do I specify custom roles?
Custom roles must use the full format: [projects|organizations]/{parent-name}/roles/{role-name}. For example, projects/my-project/roles/my-custom-role.
What properties are immutable after creation?
All properties are immutable: location, member, name, project, role, and condition. You must recreate the resource to change any of these values.
Common Use Cases
How do I grant a role to a single user?
Use WorkerPoolIamMember with role set to the desired role and member set to the user identity, such as user:jane@example.com.
How do I grant a role to multiple users at once?
Use WorkerPoolIamBinding with role set to the desired role and members containing a list of identities.
