I guess that is not really the problem, but Docker is intended to run applications not full systems like the way it works for OpenVZ now. It is even more limited. The idea is to run single binaries inside a docker container. But in real world, most applications need to run many different

Check out the concept of 'linking' in Docker. You basically build multiple containers and link them together. With links between containers, ports will be opened and restricted to and between the linked containers. It's a pretty neat concept. Basically, it becomes a clustered app. I know that

Why do you say that Docker is best run in a VM? On the contrary, I think it would be great to run Docker natively on the Proxmox host and have a visual representation of what container images have been downloaded, which ones are running and using NoVNC to attached directly to a container.

Unsafe in which way? From a security point of view of from a you might completely botch your PVE installation? If the latter, that's OK on the particular system I tried it on, as it's just a testing system. If the former, then that's more concerning, but on the host I have it, it still doesn't
