Is it just me or do other people also read the name as `chaos`?

I guess with k8s one hard part is to get it well-configured up and running and the other to maintain it and adjust to the project's needs. But seems the project tries to improve the whole experience. Good luck (honestly)!

What differentiates this from k3s? Seems like there's a lot of overlap. Would be great if there was a quick summary of why someone would use this instead of k3s/microk8s/minikube/etc.

Some googling satisfied my curiosity about the k0s vs. k3s

The name seems to imply this project is 3x smaller than K3S[0], does it use less memory, CPU? If this is all about removing external dependencies, I don't think is worth creating an entire new project to avoid installing something like `socat`.

Has anyone used K3s or this? Are they a good alternative to Dokku? I'm looking for something to either deploy on a server to host all my sideprojects (though Dokku has been basically perfect so far), or on my home server for various things like Gitea, Nextcloud and random scripts. Is K3s/K0s a good idea for either of those?

K3s is definitely more lightweight than K8s, but it still requires non-negligible resources. Compared to just a Docker engine, it takes more memory and CPU, which can be noticeable on smaller servers, Raspberry Pi, and such.

I have tried k3s and microk8s. Recently setup ArgoCD, connected to our GitLab instance. Tried both Traefik and Nginx Ingress controllers. And so on.

And dokku is better if you want a PaaS.

There are probably dokku/heroku/deis-like things that run on kubernetes, but so far I haven't found 'it'.

Of course you can just run dokku on any k8s distribution. You can even use k8s as a backend for dokku instead of docker - https://github.com/dokku/dokku-scheduler-kubernetes

Technically it is infinite times smaller than k3s or k8s :)

Ah, I see, thank you. Sounds like just manually starting docker-compose stuff will be preferable right now.
