#2Nice write-up.
Re: Anatomy of My Kubernetes Cluster
#3This is neat. I've been doing the same with Pi 1s and 2s for a few years (http://github.com/rcarmo/raspi-cluster) but stopped short of upgrading to 3s and 4s because of heat/power/cost.
I've found that it is possible to run k3s on SD cards quite well if you're patient, but that the Pi 2 master node spent a _lot_ of time just doing internal stuff even on an otherwise idle cluster, so I went back to Swarm.
(I also had quite a bit of trouble with setting up a container registry, which was hard and undocumented in the first few releases of k3s. Ingress was also a bit of a pain, it's much easier to get traefik working in Swarm...)

#4If you’d like to do something similar, check out the Turing Pi, which uses RPI compute modules and runs off a ATX power supply.

#5Nicely done. I've been meaning to dive into k8s clusters (with either k3s or kind) -- what is the advantage of building a Pi cluster over something like multiple vagrant nodes? Not criticizing at all, just trying to understand.

Not the OP (see my other comment). For me it was the cheap hardware and the fun aspects of the project. It's a tangible thing.
But I also like ARM chips and do occasional embedded development, so I had other motives :)

#7"59 Watts, That’s well above the power supplied by any AC mains to 5V DC external power supply I could find"
MeanWell has their RS-75-5, which is 60 Watts. Usually around $20.

#8More software engineers should build Kubernetes clusters like this at home...
So they don't have to do it at their work.
(Unless they work at a large enough company to justify one.)

#9Why tho? Why not just launch N KVM virtual machines on your linux box? This literally takes minutes, unlike this project which probably took days. And it's much faster once you get it up and running.

Because tinkering is fun and fun is good.
