Love Proxmox but still have to learn a lot… I use a Bind Mount Point for my dockge-LXC on proxmox.

I used the Mount Point in my docker compose:

version: “2”

services: urbackup:

image: uroni/urbackup-server:latest

container_name: urbackup

restart: unless-stopped

environment:

  - PUID=1000 # Enter the UID of the user who should own the files here

  - PGID=1000 # Enter the GID of the user who should own the files here

  - TZ=Europe/Berlin # Enter your timezone

volumes:

  - /media/urbackups/data:/var/urbackup

  - /media/urbackups/storage:/backups

  # Uncomment the next line if you want to bind-mount the www-folder

  #- /path/to/wwwfolder:/usr/share/urbackup

network_mode: host

# Activate the following two lines for BTRFS support

cap_add:

  - SYS_ADMIN

networks: {}

Now i geht this permission-error:

urbackup | usermod: no changes

urbackup | chown: changing ownership of ‘/backups’: Operation not permitted

I guess it has to do with the PUID, but i do not know the PUID.

I read that it has to be the user “urbackup” but also in the docker?

The mounted folders are both 777.

Can you help me?

    You should not be running docker in an lxc. This is happening because the docker container is trying to change ownership on the lxc bind mount and it is being blocked because it is not a privliged container.

    If you need to use docker, run it in a VM. You can mount your storage over NFS to the host. Or just run your backup solution in the lxc without docker.
