Yeah, actually I had that setup for a brief amount of time, but I had issues because my system has too little RAM, and TrueNAS and Docker were constantly fighting over RAM, and the system hang frequently. For some mindboggling reason, if I ran TrueNAS and a Docker VM separately on Proxmox, were I could manually specify allowed RAM, everything worked perfectly fine, even though the available RAM was still very low. If I ever go down this road again, I’ll need to buy more RAM sticks.
