I can’t find anything about this. The project looks still active. Perhaps it’s a confusion with k3os, a k3s operating system. https://github.com/rancher/k3os

In Ask HN: Those running K8s in house, can you please explain your architecture?

ForHackernews·Feb 15, 2021

I'd be really interested, too. Have you looked at k3s at all? We're considering trying to run https://github.com/rancher/k3os on bare metal servers.

In Running Nomad for a Home Server

aequitas·Jul 25, 2020

I finished setting up my Homelab Kubernetes setup this week. It's running two K3s[0] (a lightweight kubernetes) "clusters". One single node on a HP Microserver for media, storage, etc and one multi-node on Raspberry Pi's for IoT. For my homelab I don't need pretty autoscaling, so just a single node is enough. For the rpi's I'll probably try K3s HA cluster as they can be unreliable when the SD card eventually fails. Previously I used hand-crafted, Ansible, Salt, Puppet and Docker setups (that last one died two weeks ago prompting me to start the K3s setup). But they all ended up becomming snowflakes, making them to much hassle to maintain. What I like best about the K3s setup is that I can just flash K3OS[1] to a SD card with near zero configuration and just apply the Kubernetes resources (through Terraform in this case, but Helm is also

a great timesaver). I still have to figure out a nice way to do persistent storage. But for now since it's one node (the IoT cluster does not have state) the local-path Persistent Volumes work well enough. Might have a look into Rook. I will admit it's not trivial to get started with Kubernetes, but since I already needed to study it for work this provides me with a nice training ground. Alternatively Hashicorp offers nice solutions in this space as well with Consul and Nomad. But it needs a little bit more assembly, whereas K3s comes with batteries included (build in Traefik reverse proxy, load balancer and DNS).
