Raspberry Pi Cluster Ep 3 – Installing Kubernetes (K3s) on the Turing Pi

In this video I show you how to find new Raspberry Pis on your network and connect to them with SSH. Next, I explain Kubernetes and the many different versions of Kubernetes that you can install on a Raspberry Pi.

Finally, I set up Rancher's K3s lightweight Kubernetes distribution on the Turing Pi cluster, make sure the cluster is working properly, and then show you how to safely shut down the cluster.
