I've been running k3 on a single bigger hetzner dedicated machine to power https://demo.opensuite.online, a work-in-progress open source replacement for Google Workspace, a distribution of what the Dutch government is trying to switch to but they seemingly don't care about UX at all so I wanted to try build on their foundations (which in turn are basically just nextcloud, element, and some others).
Anyway can definitely recommend, it feels like a real cluster but it's all on a single piece of hardware which makes snapshots etc super simple.
> seemingly don't care about UX
That seems to be the case on every project with the folks that sign the checks or contracts for integrating other vendors.
I think Jobs was the rare exception there.
I've been doing the same for over a year. I think single node kubernetes is very underrated, both for running a single project or for multiple.
