Setting up wireguard docker issues

[scouserontour]

I am trying to set up wireguard docker on a proxmox server using docker compose.

I installed the docker engine using the instructions on https://docs.docker.com/engine/install/debian/

Docker version 23.0.2, build 569dd73
Docker Compose version v2.17.2
Proxmox version: pve-manager/7.4-3/9002ab8a (running kernel: 5.15.102-1-pve)

Here is my docker-compose.yaml.

version: "3" services: wireguard: image: lscr.io/linuxserver/wireguard:latest container_name: wireguard cap_add: - NET_ADMIN - SYS_MODULE environment: - PUID=1000 - PGID=1000 - TZ=Europe/London - SERVERURL=example.com # Not actual url used - SERVERPORT=51820 #optional - PEERS=myPhone #optional - PEERDNS=auto #optional - INTERNAL_SUBNET=10.13.13.0 #optional - ALLOWEDIPS=0.0.0.0/0 #optional - LOG_CONFS=true #optional volumes: - /home/paul/appdata/wireguard:/config - /lib/modules:/lib/modules ports: - 51820:51820/udp sysctls: - net.ipv4.conf.all.src_valid_mark=1 restart: always


When run I get the following error in docker compose logs wireguard:

Why is it trying to create /etc/wireguard/wg0.conf when it successfully creates /home/paul/appdata/wireguard/wg0.conf?

I have tried the same config on an a laptop running ubuntu 22.04 and I don't get this error.

Thanks,
