Have a bunch of Pis too, but realized I can use them to create a high availability control plane for a k8s cluster. Pi4s are entirely adequate for that

Could you please elaborate? I find this interesting as I'm building a k8s cluster and also have a bunch of RPIs laying around...

3x Pi 4s booting off ssd running Talos with virtual IP enabled

You know in k8s you've got worker nodes and control plane nodes? The control planes don't need much horsepower, but they're what you need to be online all to communicate with the cluster. Pis work just fine for that.

Great, I will look into that. Thank you!

Talos in general is worth a look too. I did k3s first and in hindsight should have gone straight to talos. Bit more fiddly at start but worth it
