Another tool, maybe even more 'dedicated' for Ubuntu, would be Canonical MAAS, but I never used it personally. Source: 7 months ago

Ah, I see. Yes, that is entirely possible with some engineering effort. But then you’re building a system that behaves sort of like Kubernetes, in that it serves as an availability controller machines themselves. https://maas.io/ is probably the fastest way to get there. Source: 12 months ago

Instead look at bare metal K8s solutions. I wouldn't roll your own, look at Palette (https://www.spectrocloud.com/product) which has Canonical MAAS integration for bare metal K8s. Source: 12 months ago

As it's a homelab, I do want to use it for experiments as well. I like to explore new tech, to see how it works and if it could fit my professional life as well (I work as a tech lead / architect for an semi-ecommerce store). Playing with tools like proxmox, maas.io, is fun - just because you can. But then running proxmox on some of these machines..? Source: about 1 year ago

I also use Ubuntu Server LTS in all my machines and it works perfectly fine, just install some utilities, check out RHEL Web Console for Ubuntu (aka cockpit) https://cockpit-project.org/ and the VM plugin (aka cockpit-machines), there is also a plugin to run containers and pods (aka cockpit-podman). You can also install MAAS https://maas.io/ wich is more related to Canonical/Ubuntu itself and uses LXC/LXD to do... Source: about 1 year ago
