My new Raspberry Pi cluster is a little unstable and pretty limited since the nodes have just 1GB of memory. What the heck could I possibly use this for?

Turns out it’s great at running simple cron jobs. In this case, one that cleans up old torrents on a remote qbittorrent server.

Over the holidays I made a k3s (that’s Kubernetes minus 5) cluster out of Raspberry Pis I had lying around. And while it’s extremely cool, it’s also pretty unstable.

In this post, I’ll outline what this new cluster looks like and go into detail on how I set it up. At the end, I’ll talk a little bit about why I won’t be entrusting it with my most important tasks just yet.
