Raspberry Pi Kubernetes Cluster

I have seven Raspberry Pi 3s running as part of a Kubernetes cluster with an eighth one being used as a gateway/router that connects to my network and exposes the connection to the others.

It's kind of difficult to find ARM-based Docker images for a lot of popular software to run on it and the Raspberry Pi 3s only have 1gb of RAM so they don't have much to spare. It was a good learning experience, though!

I have a few 4gb Raspberry Pi 4s with Power-over-Ethernet (PoE) HATs that would allow me to make a really clean looking and more powerful cluster... but I haven't found the time to do so. 😅
