Installing and configuring a Kubernetes cluster
This section focuses on the installation of the Kubernetes cluster and the related configurations for it. With a good understanding gained from Chapter 1, where you learned about the Kubernetes cluster architecture and Kubernetes toolings, you will perform the Kubernetes cluster installation the hard way with minikube and kubeadm, and then update the cluster version.
Note that using minikube to spin up a single node cluster is not covered in the CKA exam but it comes quite handy when you’d like to test out Kubernetes in your local machine. The same goes for using kubeadm to install a Kubernetes multi-node cluster, as well as setting up a highly available (HA) Kubernetes cluster.
We expect you to learn both ways while putting more focus on the hands-on lab working with kubeadm. Starting with the next section, we’ll walk you through the process of installing a new Kubernetes cluster and configuration.
