Examples

Here are some working examples showing some ways in which the container can be used. If you've got an interesting use for the container, or have something that someone else might find useful, feel free to add it below.

SOCKS5 proxy accessible from the LAN

Note that the socks-proxy container essentially inherits the network stack of the vpn container, so things like ports are set on the vpn container itself.

services:
    vpn:
        image: thrnz/docker-wireguard-pia
        volumes:
            - pia-dat:/pia
        ports:
            - 1080:1080
        cap_add:
            - NET_ADMIN
        environment:
            - LOCAL_NETWORK=192.168.1.0/24
            - LOC=swiss
            - USER=xxxx
            - PASS=xxxx
        sysctls:
            - net.ipv4.conf.all.src_valid_mark=1

    socks-proxy:
        image: serjs/go-socks5-proxy
        network_mode: "service:vpn"

volumes:
    pia-dat:

Bittorrent client with port forwarding

Normally qBittorent would need the listen port to be manually set to the port number shown in the vpn container's logs. This can be automated by scripting using the PORT_SCRIPT env var. Note that access to the web ui port is exposed on the vpn container itself, and that LOCAL_NETWORK must be set correctly for access from other machines on the lan.

services:
    vpn:
        image: thrnz/docker-wireguard-pia
        volumes:
            - pia-dat:/pia
            - /path/to/set_qbt_port.sh:/set_qbt_port.sh
        ports:
            - 8080:8080
        cap_add:
            - NET_ADMIN
        environment:
            - LOCAL_NETWORK=192.168.1.0/24
            - LOC=swiss
            - USER=xxxx
            - PASS=xxxx
            - PORT_FORWARDING=1
            - PORT_SCRIPT=/set_qbt_port.sh
        sysctls:
            - net.ipv4.conf.all.src_valid_mark=1

    qbittorrent:
        image: lscr.io/linuxserver/qbittorrent:latest
        network_mode: "service:vpn"
        volumes:
            - /path/to/appdata/config:/config
            - /path/to/downloads:/downloads

volumes:
    pia-dat:

The following script can be customized as needed then mounted inside the container and automatically run by setting the PORT_SCRIPT=/set_qbt_port.sh env var. Ensure that the correct permissions are set first ( chmod +x /path/to/set_qbt_port.sh).

#!/bin/bash

# The forwarded port is passed as the first argument to the script
port="$1"
QBT_USER="admin"
QBT_PASS="password"
QBT_PORT="8080"

echo "$(date): Setting qBittorrent listen port to $port..."

# Very basic retry logic so we don't fail if qBittorrent isn't running yet
 while ! curl --silent --retry 10 --retry-delay 15 --max-time 10 \
  --data-urlencode "username=${QBT_USER}" \
  --data-urlencode "password=${QBT_PASS}" \
  --output /dev/null \
  --cookie-jar /tmp/qb-cookies.txt \
  http://localhost:${QBT_PORT}/api/v2/auth/login
  do
    sleep 10
  done

curl --silent --retry 10 --retry-delay 15 --max-time 10 \
  --data 'json={"listen_port": "'"$port"'"}' \
  --output /dev/null \
  --cookie /tmp/qb-cookies.txt \
  http://localhost:${QBT_PORT}/api/v2/app/setPreferences

# Check that the port was successfully updated
if [[ $(curl --silent --retry 10 --retry-delay 15 --max-time 10 --cookie /tmp/qb-cookies.txt \
  http://localhost:${QBT_PORT}/api/v2/app/preferences | jq '.listen_port') = $port ]]; then
  echo "$(date): qBittorrent listen port successfully set to $port"
else
  echo "$(date): Error: qBittorrent port was not set"

See Issue #26 for a bit more info, including links to scripts for some other clients.

Another option is to use the PORT_FILE env var. By default the container dumps the forwarded port number to /pia-shared/port.dat which can then be mounted and monitored in other containers. Some 'helper' containers have been made for setting the listen port in qBittorrent, Transmission, and Deluge. For instance, the qBittorrent helper container example can be used as follows:

    image: scotte/qbittorrent-porthelper:latest
    container_name: qbittorrent-porthelper
    environment:
      - HOST=192.168.10.254:8080
      - USERNAME=YourqBittorrentUsernameHere
      - PASSWORD=YourqBittorrentPasswordHere
    volumes:
      - /data/software/wireguard-pia/:/piashared
    depends_on:
      - qbittorrent
