New to Proxmox and loving it! question tho?

[PatWasHere]

So I have been messing with Proxmox for about 3 weeks. Loving it. Question tho...

I have it running on an extra workstation I had lying around. With Intel(R) Core(TM) i9-10900 CPU @ 2.80GHz and no GPU. Just using the built in one from intel.

I am thinking about moving all my Plex applications and my frigate instance onto proxmox. Is it feasable to be able to share the GPU to all these containers and have it work ok?

So far I have docker, glance, Immich and HAS os installed and working ok on Proxmox. I also have frigate installed, but not configured and not running.

Right now my plex server is runing on ubuntu bare metal, all the 'arr's are running on docker (ubuntu and synology). but as i said, I'd like to move them all to the proxmox server.

If you use containers, you can share access to the device node for the GPU. This would usually be something like /dev/dri/renderD128 or similar. That's usually sufficient to allow apps like Frigate to use the GPU. If you have USB devices, such as a Coral, that you want to share, that's slightly more difficult but also doable.

Sharing resources with a VM is generally not possible, though. If your software requires a full VM, you have to use PCI-pass-through to give it access to the entire GPU. And then there is no sharing.

While not officially supported by Proxmox, you can run Docker in containers. So, that configuration is certainly doable. There is some concern that containers don't provide the same level of isolation as virtual machines, and that might make Docker in containers less secure. But honestly, if containers, virtual machines, or Docker are compromised, you have bigger problems anyway.
