| 1.Add “aufs” or “overlay” (or both) to /etc/modules-load.d/modules.conf in your PVE host and reboot. Check it with lsmod | grep -E 'overlay|aufs' | |
| 2.Use a LXC image with unprivilege features (you can check them here: https://uk.images.linuxcontainers.org/) | |
| 3.Create the container with unprivilege option, and “keyctl=1, nesting=1” features (Options section in proxmox). | |
| 4.Maybe you would want to mount an external point into /var/lib/docker (Resources section in proxmox) | |
| 5.Check this link (https://docs.docker.com/storage/storagedriver/overlayfs-driver/#configure-docker-with-the-overlay-or-overlay2-storage-driver) to change your storage-driver in docker to use aufs or overlay2. | |
| 6.Install portainer: https://portainer.readthedocs.io/en/latest/deployment.html | |

Please note that overlay/overlay2 won't when ZFS is used as the underlying filesystem. It will cause following error on the Proxmox Host:
kernel: overlayfs: filesystem on '/var/lib/docker/check-overlayfs-support458510559/upper' not supported as upperdir
It's possible to use fuse-overlayfs https://c-goes.github.io/posts/proxmox-lxc-docker-fuse-overlayfs/
"install a static version of fuse-overlayfs" any more info on this would be welcome. The rest of the steps are quite self explanatory but this is very much "just draw the rest of the damn owl" territory.
"install a static version of fuse-overlayfs" any more info on this would be welcome.
It's a single binary you can copy to /usr/local/bin/fuse-overlayfs available at https://github.com/containers/fuse-overlayfs/releases
Docker should work as soon as you can call fuse-overlayfs --version.
There is also the fuse-overlayfs package in ubuntu but it's maybe too old. But should work as well.
Thank you! <3

Hey there,
wanted to pop bye te tell you that your Blogpost helped me fixing my issues as discussed here: https://forums.docker.com/t/docker-daemon-stops-from-time-to-time
Wanted to tell you, since you don't allow comments on your blog, that for me it worked on Proxmox only with nesting and FUSE enabled. The other features are not needed in my case.
Cheers!
Fuse-Overlay seems to break Proxmox Backups, I haaven't found a solution yet, but it cannot backup the /var/lib/docker/fuse-overlay/ directory in full with this config.
Aaaah that’s the reason, I see. Well my fix was to backup with the stop mode, not Snapshot or suspend
