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 approaches: single-member grants (non-authoritative), multi-member role management (role-authoritative), and complete policy replacement (fully authoritative).

IAM resources for worker pools come in three variants with different authorization behaviors. WorkerPoolIamMember adds one identity without affecting others; WorkerPoolIamBinding controls all members for a role; WorkerPoolIamPolicy replaces the entire policy. 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 add one identity to a role 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")

		})

	})

    properties:

      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 with the same role, making it safe for incremental access grants.

Grant a role to multiple members at once

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

      members:

The members property lists all identities that should have this 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. WorkerPoolIamBinding cannot be used with WorkerPoolIamPolicy (they conflict), but can coexist with WorkerPoolIamMember if they manage different roles.

Replace the entire IAM policy

Some deployments require complete control over all roles and members, replacing any existing policy.

const admin = gcp.organizations.getIAMPolicy({
    bindings: [{

The policyData property accepts output from getIAMPolicy, which defines bindings (role-to-members mappings) in a structured format. This resource is fully authoritative: it replaces the entire IAM policy on the worker pool. WorkerPoolIamPolicy conflicts with both WorkerPoolIamBinding and WorkerPoolIamMember; using them together causes Pulumi to fight over the policy state.

Beyond these examples

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

The examples reference pre-existing infrastructure such as Cloud Run v2 worker pools and a GCP project with configured location. They focus on IAM binding 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 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 WorkerPoolIamMember resource reference for all available configuration options.

Frequently Asked Questions

Resource Selection & Conflicts
Which IAM resource should I use for WorkerPool permissions?
Choose based on your needs: WorkerPoolIamPolicy is authoritative and replaces the entire policy, WorkerPoolIamBinding is authoritative for a specific role while preserving other roles, and WorkerPoolIamMember is non-authoritative and preserves other members for the same role.
Can I use WorkerPoolIamPolicy with WorkerPoolIamBinding or WorkerPoolIamMember?
No, WorkerPoolIamPolicy cannot be used together with WorkerPoolIamBinding or WorkerPoolIamMember because they will conflict over the policy configuration.
Can I use WorkerPoolIamBinding and WorkerPoolIamMember together?
Yes, but only if they grant privileges to different roles. Using both for the same role will cause conflicts.
Configuration & Identity Formats
What identity formats can I use in the member field?
You can use allUsers, allAuthenticatedUsers, user:{email}, serviceAccount:{email}, group:{email}, domain:{domain}, projectOwner/Editor/Viewer:{projectid}, and federated identities like principal://iam.googleapis.com/....
Are location, name, and project changeable after creation?
No, all three properties are immutable and used to identify the parent WorkerPool resource.
Custom Roles & Advanced Usage
How do I specify custom roles?
Custom roles must use the full path format: [projects|organizations]/{parent-name}/roles/{role-name}, for example projects/my-project/roles/my-custom-role.
