We've learned most of our basic DevOps skills with Kubernetes in previous chapters, from how to containerize our application to deploying our containerized software into Kubernetes seamlessly via continuous deployment. Now, it's time to have a deeper insight into how to administer a Kubernetes cluster.
In this chapter, we'll learn:
- How to utilize namespaces to set administrative boundaries
- Using kubeconfig to switch between multiple clusters
- Kubernetes authentication
- Kubernetes authorization
While minikube is a fairly simple environment, we will use the Google Container Engine (GKE) and self-hosted cluster in AWS as the example, instead of minikube in this chapter. For the detailed setting, please refer to Chapter 9, Kubernetes on AWS, and Chapter 10, Kubernetes on GCP.
