client-go Examples

This directory contains examples that cover various use cases and functionality for client-go.

Configuration

• Authenticate in cluster: Configure a client while running inside the Kubernetes cluster.
• Authenticate out of cluster: Configure a client to access a Kubernetes cluster from outside.

Basics

• Managing resources with API: Create, get, update, delete a Deployment resource.

Advanced Concepts

• Work queues: Create a hotloop-free controller with the rate-limited workqueue and the informer framework.
• Custom Resource Definition (successor of TPR): Register a custom resource type with the API, create/update/query this custom type, and write a controller that drives the cluster state based on the changes to the custom resources.

Testing

• Fake Client: Use a fake client in tests.
