I have a trusty UnRaid server that has been running great for almost 3 years now, with some kinks and headaches here and there, but mostly very stable. Now I’m entertaining the idea of setting that box up with ProxMox, and running UnRaid virtualized. The reason being that I want to use UnRaid exclusively as a NAS and then run all dockers and VMs on ProxMox (at least that’s how I’m picturing it). I would like to know your opinion on this idea. All I have is Nextcloud, Immich, Vaultwarden, Jellyfin, Calibre, Kavita and a Windows VM I use to update some hardware every now and then. I mainly want to do that for the backup capabilities in ProxMox for each instance. Storage is not a concern, and I have 64GB of ECC Ram running in that box. What are the Pros and Cons, or is it even worth it to move all this to ProxMox?
How is running a container in an LXC worse than in a VM? It’s not really, is it? No, not really. Kubernetes could also be built on top of the LXC as well, sure. There are a number of genuine benifits from running docker on top of an LXC, and it doesn’t compromise security or come with a significant performance drop (unlike VMs).
I was suggesting to do neither and run the container directly. Putting k8s on top of lxc is still completely stupid. Just run k8s bare metal to operate your containers.
