This 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 ha…

This seems to be a Kubernetes thing. Why the hell does it idle using 25% of my 4 CPUs?

Remind me why we need this technology again?

Real question coming from a non-k8-user. What would you use something like this for? Server hosting or?

It looks like this is being used more as an educational tool for the authors daughter than it is being used for a production workload.

Kube is basically fancy systemd built to run on multiple machines. If you wanted to you could use this for anything you could use one bigger machine and systemd to do.

Earlier quoted context omitted.

Just about anything not Kubernetes related. I'm currently building a cat toy which combines object detection and reverse kinematics to play with my cat using a laser pointer when she steps into view of the camera.

Why tho? Why not just use a laser pointer yourself? This literally takes minutes, unlike this project which probably took days. And it's much faster once you get it up and running.

AI and robotics tho. Way cooler than some stupid Kubernetes that doesn't even work well on this hardware.

I know it's a novel concept that not many know about, but: Everyone has their own interests and curiosities.

That makes no sense. Try looking at logs and such at least.

Why 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 this is literally what "Hacker News" should be about.
