I would LOVE it if proxmox supported docker (or podman) out-of-the-box. (I mean with docker/podman showing up in the gui, just like LXC containers and vms)

LXC is just a container, docker is much more than just that. It is a recipe (dockerfiles), it is sort of a social project sharing setup, it is like a version control system (the layered filesystem that only updates changes), it is a disposable dev container, it is a deployable runtime container, etc

I run nested Docker in unprivileged LXC on Proxmox on ZFS since 2019 without problems. Gitlab, Nextcloud, mailcow-dockerized etc., for 10 people, - altogether 10 LXC with about 25 Docker services, 1-2% CPU utilization on average, thanks to sharing all resources of the host. I've written a blog post about it [1].

This is one of the reasons is switched to TrueNas Scale for my HomeServer. Before that I always had a VM that was the Docker Host and another one with OpenMediaVault as Backup Server. Both these VMs are replaced by TrueNas. Less complexity and less maintenance overhead.

Have you by chance tried GPU passthrough on TrueNAS Scale? I'm planning a Homelab do-over this summer and one requirement is to have a Windows VM with a dedicated GPU I can use as a Steam host via Parsec.

I haven't used TrueNAS since it was FreeNAS and BSD based.
