Summary: What Does Kubernetes Look Like?

Recap

In this chapter, we explored different types of nodes.

We learned that Kubernetes clusters comprise control plane nodes and worker nodes. These can run almost anywhere, including bare metal servers, virtual machines, and the cloud. Control plane nodes run the back-end services that keep the cluster running, whereas worker nodes run business applications.

Most cloud platforms offer a hosted Kubernetes service. This is an easy way to get a production-grade cluster, where the cloud provider manages performance, availability, and updates. You manage the worker nodes and pay the bill.

We also learned that kubectl is the Kubernetes command line tool.
