Before installing Kubernetes, we need to have an overview of its architecture and main components, because Kubernetes is not a simple tool but is a cluster—that is, it consists of a master server and other slave servers called nodes.

I suggest you explore the architecture of Kubernetes in a simplified way.

Kubernetes architecture overview

Kubernetes is a platform that is made up of several components that assemble together and extend on demand, in order to enable better scalability of applications. The architecture of Kubernetes, which is a client/server type, can be represented simply, as shown in the following diagram:

Figure 10.1 – Kubernetes architecture

In the previous diagram, we can see that a cluster is made up of a master component and nodes (also called worker nodes), which represent the slave servers.

In each of these nodes, there are pods, which are virtual elements that will contain containers...
