Manage GCP Cloud Run Worker Pool IAM Bindings

The gcp:cloudrunv2/workerPoolIamBinding:WorkerPoolIamBinding resource, part of the Pulumi GCP provider, manages IAM access control for Cloud Run v2 worker pools by granting roles to members. This guide focuses on three capabilities: authoritative role binding to multiple members, non-authoritative single member grants, and full policy replacement with data sources.

These IAM resources reference existing worker pools and require project and location identifiers. The examples are intentionally small. Combine them with your own worker pool infrastructure and identity management.

Grant a role to multiple members at once

When multiple users or service accounts need the same access level, WorkerPoolIamBinding grants a role to all specified members in one resource.

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

const binding = new gcp.cloudrunv2.WorkerPoolIamBinding("binding", {
    project: _default.project,
    location: _default.location,
    name: _default.name,
    role: "roles/viewer",
    members: ["user:jane@example.com"],
});

import pulumi
import pulumi_gcp as gcp

binding = gcp.cloudrunv2.WorkerPoolIamBinding("binding",
    project=default["project"],
    location=default["location"],
    name=default["name"],
    role="roles/viewer",
    members=["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.NewWorkerPoolIamBinding(ctx, "binding", &cloudrunv2.WorkerPoolIamBindingArgs{
			Project:  pulumi.Any(_default.Project),
			Location: pulumi.Any(_default.Location),
			Name:     pulumi.Any(_default.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.CloudRunV2.WorkerPoolIamBinding("binding", new()
    {
        Project = @default.Project,
        Location = @default.Location,
        Name = @default.Name,
        Role = "roles/viewer",

      role: roles/viewer
      members:

The role property specifies which permission set to grant (e.g., “roles/viewer”). The members array lists all identities receiving that role. This resource is authoritative for the specified role: it replaces any existing members for that role but preserves other roles on the worker pool.

Add a single member to a role incrementally

Teams managing access across multiple stacks or adding members without affecting existing grants use WorkerPoolIamMember for non-authoritative updates.

The member property specifies a single identity to grant access. Unlike WorkerPoolIamBinding, this resource adds the member without replacing others who already have the role. You can use multiple WorkerPoolIamMember resources for the same role without conflicts.

Replace the entire IAM policy with a data source

Organizations with centralized IAM policies use WorkerPoolIamPolicy to define the complete access control list, replacing any existing policy.

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"],
    }],
});
const policy = new gcp.cloudrunv2.WorkerPoolIamPolicy("policy", {
    project: _default.project,
    location: _default.location,
    name: _default.name,
    policyData: admin.then(admin => admin.policyData),
});

import pulumi
import pulumi_gcp as gcp

admin = gcp.organizations.get_iam_policy(bindings=[{
    "role": "roles/viewer",
    "members": ["user:jane@example.com"],
}])
policy = gcp.cloudrunv2.WorkerPoolIamPolicy("policy",

)

func main() {
	pulumi.Run(func(ctx *pulumi.Context) error {
		admin, err := organizations.LookupIAMPolicy(ctx, &organizations.LookupIAMPolicyArgs{
			Bindings: []organizations.GetIAMPolicyBinding{
				{
					Role: "roles/viewer",
					Members: []string{
						"user:jane@example.com",
					},
				},
			},
		}, nil)
		if err != nil {
			return err
		}
		_, err = cloudrunv2.NewWorkerPoolIamPolicy(ctx, "policy", &cloudrunv2.WorkerPoolIamPolicyArgs{
			Project:    pulumi.Any(_default.Project),
			Location:   pulumi.Any(_default.Location),
			Name:       pulumi.Any(_default.Name),
			PolicyData: pulumi.String(admin.PolicyData),

            members:
              - user:jane@example.com

The policyData property accepts output from the getIAMPolicy data source, which defines all roles and members. This resource is fully authoritative: it replaces the entire IAM policy. It cannot be used alongside WorkerPoolIamBinding or WorkerPoolIamMember, as they would conflict over policy ownership.

Beyond these examples

These snippets focus on specific IAM management features: role-based access control, incremental vs authoritative IAM updates, and policy data source integration. They’re intentionally minimal rather than full access control systems.

The examples reference pre-existing infrastructure such as Cloud Run v2 worker pools and GCP projects with configured locations. They focus on configuring IAM bindings rather than provisioning the underlying worker pool resources.

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

Conditional IAM bindings (condition property)
Custom role definitions and formatting
Service account creation and management
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 WorkerPoolIamBinding resource reference for all available configuration options.

Frequently Asked Questions

Resource Selection & Conflicts

What's the difference between WorkerPoolIamPolicy, WorkerPoolIamBinding, and WorkerPoolIamMember?

WorkerPoolIamPolicy is fully authoritative and replaces the entire IAM policy. WorkerPoolIamBinding is authoritative for a specific role, managing all members for that role while preserving other roles. WorkerPoolIamMember is non-authoritative, adding a single member to a role without affecting other members.

Which IAM resources can I use together?

You cannot use WorkerPoolIamPolicy with WorkerPoolIamBinding or WorkerPoolIamMember, as they will conflict. However, you can use WorkerPoolIamBinding with WorkerPoolIamMember only if they manage different roles.

Why am I seeing IAM policy conflicts?

Mixing WorkerPoolIamPolicy with WorkerPoolIamBinding or WorkerPoolIamMember causes them to fight over the policy. Similarly, using WorkerPoolIamBinding and WorkerPoolIamMember for the same role creates conflicts.

IAM Configuration

What member identity formats are supported?

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 grant a role to multiple users at once?

Use WorkerPoolIamBinding with the members array containing multiple identities, such as ["user:jane@example.com", "user:john@example.com"].

How do I add a single user to a role without affecting other members?

Use WorkerPoolIamMember with the member property set to a single identity like user:jane@example.com. This is non-authoritative and preserves existing members.

Custom Roles

What format do custom roles require?

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