My First Kubernetes: k3s 'cluster' on 3 Orange Pi Zero 3's

I did something similar a few years back and wrote a blog series about it[0].

Ultimately, I ripped it apart and stuck to using my x86 servers and now run Talos Linux[1] which is currently my favourite way to do Kubernetes on bare metal.

With Pi4, the cluster services just used too much of the available compute and though it was a fun project, want practical for my home lab.

Now the Pi5 is available (and I have some), I might look at adding them to my existing clusters for some mixed-architecture fun.

I'm also having some fun with Talos@RPi4s[0] for NAS usage.

Booted it few months ago, but only this week got to actually configure and use it.

That's a sweet setup.

Have you come across Longhorn[0]?

I wanted to have a look at that for storage when I was using Pis as it theoretically should be lighter-weight than Ceph, who knows. Didn't get around to it though.
