Authentication for containerized applications running on Google Kubernetes Engine or GKE Enterprise is handled differently between local testing environments and Google Cloud environments.
Test containerized applications locally
To test your containerized application on your local workstation, you can configure your container to authenticate with your local ADC file. For more information, see Configure ADC with your Google Account.
To test your implementation, use a local Kubernetes implementation such as
minikube and the gcp-auth addon.
Run containerized applications on Google Cloud
You set up authentication for Google Cloud containerized environments differently depending on the environment:
- For GKE Enterprise, see the authentication overview and Use fleet Workload Identity Federation for GKE.
- For GKE, see Access Google Cloud APIs from GKE workloads.
- For Knative serving, see Using Workload Identity Federation for GKE for Knative serving.
