We will go through advanced topics on administration in this chapter. First, you will learn how to use kubeconfig to manage different clusters. Then, we will work on computing resources in nodes. Kubernetes provides a friendly user interface to illustrate the current status of resources, such as the replication controller, nodes, and pods. You will learn how to build and administrate it.

Next, you will learn how to work with the RESTful API that Kubernetes exposes. It will be a handy way to integrate with other systems. Finally, we want to build a secure cluster; the last section will go through how to set up authentication and authorization in Kubernetes.
