Using kubeadm to install a basic Kubernetes cluster

In this section, we will create a multi-node Kubernetes cluster using kubeadm. The following are the steps we need to achieve the goal:

1. Install kubeadm.
2. Bootstrap a master node where your control plane will be located
3. Install the network plugins (we will get to the detailed supported plugins later in this chapter and use Calico as an example in that section).
4. Bootstrap the worker nodes.
5. Join the worker nodes to the control plane.

Before getting started, you need to make sure your master node meets all the technical requirements listed in this chapter.

We’ll deploy a basic Kubernetes cluster by going through the steps described in this section, as shown in Figure 2.7:

The Kubernetes cluster will be similar to the architecture featured in Figure 2.14:
