Connect NFS share to Docker

[pixelwave]

Hi,

I am not sure if that is the right place but maybe someone can help me understanding an error ...

The following setup:

• Proxmox as Hypervisor
• TrueNAS Scale as VM
• Ubuntu with Docker & Portainer as LXC

Now I did setup an NFS share in my TrueNAS system and shared it with the proxmox host. Works fine!



Now I want to setup a volume in my portainer instance referencing to an NFS share from the TrueNAS system as well.. but I get "Failure Request failed with status code 500" when I try to mount the volume in a container?




I even setup "Mapall User" and entered the IP address of the portainer instance in the TrueNAS nfs settings:





... what am I missing?

So I just double-checked with a fresh debian vm install (instead of LXC container). There is works. So it seems to be a limitation of the LXC setup. I also tried to uncheck "unprivileged" in the install but then I got plenty of "app armour" error when trying to install portainer ...

Ok going further it seems to be a problem with the ubuntu template. I now installed Debian 11 (Standard LXC template) as privileged container and it works!
