Install Kubernetes on Ubuntu 22.04 with MicroK8s


Kubernetes is a complex beast, with lots of available drivers and plugins to handle different types of clusters. For example, to handle networking between pods in the cluster, you must install a CNI (Container Network Interface) plugin like Flannel, Calico, Weave Net, Cilium or other.
