Summary: Kubernetes Cluster

Recap

In this chapter, we explored different types of nodes.

We learned that Kubernetes clusters are made up of control plane nodes and worker nodes. These can run almost anywhere, including bare metal servers, virtual machines, and in 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. These are 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.
