Interesting idea. Wonder how much extra work would be involved to get them to network boot instead of messing with sd cards.

I actually thought about this first! Doing a PXE boot, but wanted something easier to replicate in a guide for other people in the community.

But the reality is it wouldn’t be too difficult. Something like this: https://www.raspberrypi.org/documentation/hardware/raspberry...

Very cool. So you have two SD cards, one for infra nodes and one for worker nodes, is that right?

Correct. One for master nodes. One for worker nodes.

The code is all the same on the SD cards just conditional logic depending on the type.

So if I buy four Raspberry pis and plug Infra sd in 2 of them and worker sd in the other 2 and connect them all direct to my router will it be a working Kubernetes cluster with ZERO additional setup?

Correct. That’s what I meant by headless, but I think that’s probably confused people with trying to call “kubernetes” headless. My bad.

As long as you follow the guide with setup then that’s right.
