raspberrypi

If you’re anything like me, your home lab is constantly changing, evolving, breaking, rebuilding. For the last year or so I’ve been running all my home kubernetes workloads on a Raspberry Pi cluster - and it’s been working really well! I’ve been through several iterations - for example firstly running on SD cards (tl;dr - it’s bad, they wear out really fast with Kubernetes on board!), then PxE booting them from my Synology to it’s now current state of booting directly from SSDs.

I love Raspbery Pis - I have done since they first released them, all the way up to the present iteration, the Raspberry Pi 4. They’re phenominal little bits of kit, endlessly hackable and because of their really low price, they open up computing to a huge number of people who otherwise wouldn’t get the opportunity. One of the irritating things, though, about running Raspberry Pis is that they typically boot from an SD card.
