Errors should give more context

[Jean François CASSAN]

Describe the bug
I'm trying to run the docker image in my docker stack, wireguard itself is running as a docker image. It's the wireguard-go because of difficulties to get the kernel module running on my rig.

To Reproduce
I have includes this image as docker-compose service like following:

  wireguard-ui:
    image: embarkstudios/wireguard-ui:latest
    container_name: wireguard-ui
    entrypoint: "/wireguard-ui" 
    privileged: true
    command:
      - --log-level=debug
    volumes:
      - "/tank2/docker_data/wireguard/config:/etc/wireguard"
      - "./wireguard-ui:/data"
    ports:
      - "8081:8080"
      - "5555:5555"

    labels:
      - "traefik.enable=false"

When I start the container, I get level=fatal msg="operation not supported" which is not informative

Expected behavior
I'd expect more context on the error as it is now common with golang using error wrapping to get something like "Configuration file creation: operation not supported".

I'm quite sure the problem is in my config, but without context, it's hard to troubleshot it.

• OS: debian 10 / docker

The Wireguard device created by wireguard-go existed in the default network namespace. Execute "ip a" will print all network interface, it will be wg0 usually. wireguard-ui will can not operates it in an isolated network namespace in the container.

You can try to set the container's network to host mode. You may need to add network_mode: "host" in your docker compose file or --net=host in your docker run command.

Or wireguard-ui maybe could manage a userspace Wireguard in its container.

@simulot do you still have problems with this? In case you do I would advice you to try embarkstudios/wireguard-ui:userspace which @m0ssc0de has provided that could solve your problem.

I gave up with dokerized wireguard-go on my NAS a while ago. I have placed wireguard on another device using kernel module.

So I can't test the solution any more.
Thanks you for your help.
