SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill requires google-cloud-storage, google-cloud-secretmanager, and includes scripts (resource) components.

What problem does it solve?

Workload Identity Federation eliminates the need for static service account keys by enabling containers to authenticate to cloud providers using short‑lived tokens, reducing secret sprawl and key lifecycles.

Core Features & Use Cases

  • Keyless authentication: Bind Kubernetes ServiceAccounts to cloud service accounts to obtain ephemeral credentials at runtime.
  • Cross‑project IAM and impersonation: Grant least-privilege access across projects without embedding credentials.
  • Migration & operations: Provides guidance to migrate from key-based workflows and operate with zero‑touch credential rotation.

Quick Start

Enable Workload Identity on your GKE cluster, create and bind a Kubernetes ServiceAccount to a GCP service account, then deploy workloads that use the bound identity.

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How does Workload Identity Federation replace static GCP service account keys?

Workload Identity Federation replaces static GCP service account keys by binding Kubernetes ServiceAccounts to GCP service accounts, allowing containers to authenticate using short-lived ephemeral tokens instead of managing long-lived credentials.

What is the best way to set up Workload Identity on a GKE cluster?

To set up Workload Identity on a GKE cluster, enable the cluster workload identity pool, create a GCP service account, configure IAM bindings, create an annotated Kubernetes ServiceAccount, and deploy your workloads to use the bound identity.

Can I use Workload Identity Federation for cross-project IAM access in GKE?

Yes, Workload Identity Federation supports cross-project IAM access and impersonation, granting least-privilege permissions across projects without embedding static credentials in your container workloads.

How do I migrate from key-based authentication to Workload Identity Federation?

Migrating from key-based workflows to Workload Identity Federation involves creating new IAM bindings and annotated Kubernetes ServiceAccounts, deploying workloads with the bound identity, and removing static keys for zero-touch credential rotation.

Why is my GKE Workload Identity Federation setup not working?

Troubleshooting GKE Workload Identity Federation involves verifying the cluster workload identity pool is enabled, checking IAM bindings between the GCP and Kubernetes ServiceAccounts, and ensuring the Kubernetes ServiceAccount is correctly annotated.

Do I need google-cloud-secretmanager if I use Workload Identity Federation?

While Workload Identity Federation eliminates static keys, you may still use google-cloud-secretmanager and google-cloud-storage as dependencies, with workloads authenticating to these services using ephemeral tokens instead of embedded credentials.
