ansible-libvirt-microos VS cluster-api-k3s

I've been using a 3 nuc (actually Ryzen devices) k3s on SuSE MicroOS https://microos.opensuse.org/ for my homelab for a while, and I really like it. They made some really nice decisions on which parts of k8s to trim down and which Networking / LB / Ingress to use.

The option to use sqlite in place of etcd on an even lighter single node setup makes it super interesting for even lighter weight homelab container environment setups.

I even use it with Longhorn https://longhorn.io/ for shared block storage on the mini cluster.

If anyone uses it with MicroOS, just make sure you switch to kured https://kured.dev/ for the transactional-updates reboot method.

I'd love to compare it against Talos https://www.talos.dev/ but their lack of support for a persistent storage partition (only separate storage device) really hurts most small home / office usage I'd want to try.

What are the advantages of your project over conceptually similar projects that already exist, like MicroOS (https://microos.opensuse.org/) ?

I would suggest you to check either Leap Micro or MicroOS out.

I use MicroOS (https://microos.opensuse.org/), to keep the base operating system clean you'd install helper tools for constructing containers in a container... so two levels of containers would be very helpful

Where OpenSuse is interesting, definitely, it's with the MicroOS concept of Immutable Installs + their strategy of btrfs snapshots - this looks absolutely great from a stability standpoint ; there are other possible strategies out there, but these people are building a truly unbreakable distro and that's fantastic.

I'm currently running/testing openSUSE's new MicroOS which is really nice but still needs some work

Hi! I just wanted to drop by ansible-libvirt-microos ; since I'm using MicroOS already on a personal server, I decided to make better usage of it, by converting it into a VM host, and setting up another VM inside so that I can deploy more vms with extra steps containers via k3s.

If you want to get an HA k3s cluster going quickly on your cloud-provider of choice: https://github.com/cluster-api-provider-k3s/cluster-api-k3s

I have also been interested in this. I think you are looking for a custom bootstrap provider. I found this. But something similar might exist I didn't search much.

The provider integration doesn't have any strong opinions on the installed kubernetes version. The cluster-api project and the two controllers cluster-api-bootstrap-provider-kubeadm and cluster-api-control-plane-provider-kubeadm are usually responsible for the kubernetes part. Right now we support in hcloud also talos based kubernetes and I found in a quick research this project: https://github.com/zawachte/cluster-api-k3s Which aims to do k3s with cluster-api. But I think if you're really interested in running k3s with cluster-api this is more a question to https://github.com/kubernetes-sigs/cluster-api
