Advice for setting up baremetal k8s lab (lemmy.blahaj.zone)

I just got myself some mini PC's and want to set up a k8s lab to strengthen my skills, I was laid off 8mo ago and haven't been able to find a new job.

I want to automate everything I can while building this and was just looking for input on how people might recommend I do it.

I was thinking of using pxeboot to install Debian using preseed to automate the installation.

Then maybe install k8s on VMs on the servers, but I'm not sure if I should do that or just keep it on the hosts themselves. They're decently specced. AMD Ryzen 3 2200 CPUs with 24gb ram and an SSD/NVME combo.

So, any advice for where I should start or tips/tricks?

I've been setting up a baremetal Talos-based cluster on 4 SFF machines and using Flux to declaratively deploy things to the cluster. Once you wrap your head around how Flux operates, deploying things becomes fairly straightforward.

For me, the most difficult process was deploying the cluster properly, but the recent-ish video posted on the Tailscale YT channel helped a LOT.
