Proxmox bind mounts are a nightmare for user permissions (lemmy.world)

Hi, I need help to understand what I am doing wrong with my setup.

I am running a proxmox node (pve) where I have mounted my nfs storage (containing backups from my old server) on the host and assigning them to containers using pct set command.

On Host:I am setting the user permissions to the mounted folder so that the user from lxc can rw to it and the sub-folders(or atleast I thought it would be possible).

On Unpreviledged LXC:The mount is recognized and is accessible with the correct user permissions to rw

The docker container created inside the lxc is unable to read/write to this storage even though they are assigned to the correct user id 1000. The docker setup is logging errors and won't start up.

Appreciate the help!

In incus, I had the same setup of an LCX container with a Docker container inside of it. I passed 1000/1000 to the LXC container but the LXC container’s default root user has a an ID set of 0/0. So I had to pass 0/0 to the Docker container, not 1000/1000 to get the read/write permissions working.

That may fix your issue as it’s basically the same tech, just different automated things implementing the LXC container!
