Learning Kubernetes with k3s

I am working on learning Kubernetes, aka k8s, and want to set up a cluster in my homelab so I can learn and experiment.

I have tried to install a 3-node cluster using k3s but haven't been able to get it working so far.

Today I'm trying something different: I'm working through a course entitled Building a Raspberry Pi 4 Kubernetes Cluster from Pluralsight. It's geared towards Raspberry Pi machines, but importantly it uses the k3s distribution of Kubernetes from Rancher, so I'll be able to run it on my Ubuntu boxes.

I'll add more to this post as I work through the course.
