However docker containers have their use cases. I settled for a Debian lxc in proxmox with nesting feature enabled and running the containers in there. On the proxmox instance you have to enable the overlay and aufs Kernel models otherwise the lxc will quickly run out of space. To do that:

Edit the container config like: vim /etc/pve/lxc/113.conf. Add the extra lines: lxc.apparmor.profile: unconfined lxc.cgroup.devices.allow: a lxc.cap.drop: Shutdown and restart the container. To enable aufs/overlay in the container, it actually needs to be loaded on the proxmox host, this can be done with: modprobe aufs modprobe overlay
