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?
Proxmox is Debian at its core, which is supported by Docker. There’s no good reason to not run Docker on the bare metal in a homelab. I’d be curious to know what statement Proxmox has made about supporting Docker. I’ve found nothing.
I bought a used machine a couple weeks ago and am setting it up (1st bare metal build), prox with debian vm running docker. I found it annoying that pm doesn’t support it natively but the ability to do snapshots through pm is nice, and let’s me fuck around more than I would otherwise, slowly build up a machine.
But almost all of the stuff I have running on other machines is just docker containers, so it would be nice if pm just added a checkbox during install or something. (I want to poke at and learn pm, plus mess around with other vms, that’s why I didn’t do straight Debian)
LXCs let you get all the benifits of VMs with fewer drawbacks, I recommend that approach if you want some extra sandboxing than docker on bare metal provides.
That’s not a definitive support statement about Docker being unsupported. In fact, even in the Admin Guide, it only provides recommendations. The comment I replied said Docker is unsupported by Proxmox. I maintain that there is no such statement from Proxmox.
Maybe not explicitly unsupported, but I think “it interferes with some mechanisms on which we rely” should be more discouraging than a policy statement.

I am with you on the advantages of running it in a VM. The isolation a VM provides is really nice. Snapshots FTW.

Second result for “docker on proxmox”.
