Back to a teach-myself-something type of project, with setting up K8s Cluster on Raspberry Pi devices. I had a couple of older Raspberry Pi 3s and a recently purchased Pi 4 available for this. My old Pi3 devices had Docker Swarm (yes that one) from a couple of years back. This time around I want to get k8s on the 3 Pi devices.

The steps are fairly simple but it can be a bit of work. You should find blogs out there with decent enough directions. So here goes me adding to that library of blogs to make it easier for the next person trying to set this up.

Taming your Microservice & Container Envy
