Fails to start when disabling IPv6

JJGO commented 3 years ago

Using the following docker-compose.yml from the docs

version: "3.7"

services:
  qbittorrent:
    container_name: qbittorrent
    image: hotio/qbittorrent
    ports:
      - "8080:8080"
      - "8118:8118"
    environment:
      - PUID=1001
      - PGID=1001
      - UMASK=002
      - TZ=Etc/UTC
      - VPN_ENABLED=true
      - VPN_LAN_NETWORK=172.18.0.0/16
      - VPN_CONF=wg0
      # - VPN_ADDITIONAL_PORTS=7878/tcp,9117/tcp
      - PRIVOXY_ENABLED=false
    volumes:
      - ./config:/config
    cap_add:
      - NET_ADMIN
    sysctls:
      - net.ipv4.conf.all.src_valid_mark=1
      - net.ipv6.conf.all.disable_ipv6=1

And I'm getting the following trace (see below). I believe the issue is related to the Error: IPv6 is disabled on nexthop device. but not sure why IPv6 is needed when I specified net.ipv6.conf.all.disable_ipv6=1 in the docker-compose.

$ docker-compose up

Remove all ipv6 related stuff from your wg0.conf

Thanks. Removing all ipv6 related entries solved the issue. In my case it was a wireguard container trying to access the WG server running also in a container. The client configuration contained a "::a" entry. :

hotio / qbittorrent
