Hey breh. My setup us bare metal proxmox, a truenas VM and a couple Debian LXCs. Main LXC is running docker just fine with zero issues.

I’d honestly suggest skipping the truenas VM and just managing your disks in proxmox but my setup has been holding steady for about 5 years now.

Definitely don’t have to choose between lxc or docker.

I virtualized my nas for memes but honestly you don’t even need to do that. Just run proxmox and use zfs then build whatever lxc/VMS you want on top of it

Honestly I’m surprised more people don’t do it. Its so easy.

This is what ive been doing for about a year and I love it.
