Kubernetes Components Overview
By completing the previous exercise, you have a single-node Kubernetes cluster up and running. Before playing your first concert, let's hold on a second and pull the curtains aside to take a look backstage to see how Kubernetes is architected behind the scenes, and then check how Minikube glues its various components together inside its VM.
Kubernetes has several core components that make the wheels of the machine turn. They are as follows:
- API server
