Part of collection: Hyper-converged Homelab with Proxmox
Update 09-10-2025: I have moved on to a setup with Docker LXC on Proxmox, with bind-mounts (without VirtioFS) as described in Gist Docker Swarm in Vm's with CephFS.
After struggling for some days, and since I really needed this to work (ignoring the it can't be done vibe everywhere), I managed to get Docker to work reliable in privileged Debian 12 LXC Containers on Proxmox 8
(Unfortunately, I couldn't get anything to work in unprivileged LXC Containers)
