Speaking of That Cluster…

Last November, I threatened to build a Kubernetes cluster out of Raspberry Pi 3s. Well I actually did it starting during the December holidays and finishing up in January. Here’s a picture of it:

Raspberry Pi k8s Cluster

The one warning, that’s not obvious from the construction guide, is that the Raspberry Pi ARM processor architecture typically doesn’t have popular Docker images publicly available. This makes it somewhat challenging to do anything further usefully non-trivial. All-in-all, while not cheap, it was still a fun project and handy to have a k8s lab at home to play with.
