Alpine Linux running rTorrent + RuTorrent WebUI for docker with OpenVPN support. This container is inspired by the work of wonderfall ; drgroot ; haugene

I needed a container based on Alpine Linux using RuTorrent and OpenVPN

Listen to port 80 using NGinx + PHP-FPM (reverse proxy recommended for SSL and authentication, I recommend jwilder/nginx-proxy).

Note: Requires priviledged run in order to connect using OpenVPN (or just NET_ADMIN capability).

It's my first docker build so it may be far from perfect. Don't hesitate to reach me if you find something that can be enhanced or corrected.

docker create -t --name=rtorrent \
--add-cap NET_ADMIN \
-v <path to OpenVPN conf files>:/home/rtorrent/vpn \
-v <path to rTorrent session files>:/home/rtorrent/session \
-v <path to rTorrent downloads/complete>:/home/rtorrent/downloads/complete \
-v <path to rTorrent downloads/incomplete>:/home/rtorrent/downloads/incomplete \
-v <path to rTorrent watch directory>:/home/rtorrent/watch \
-v <path to RuTorrent plugins>:/var/www/rutorrent/plugins \
-v <path to RuTorrent themes>:/var/www/rutorrent/themes \
-p 80:80 -p 49161:49161 \
sawn/rtorrent-rutorrent-openvpn

Or using Docker-Compose v2+:

version: '2'
services:
  rtorrent:
    image: sawn/rtorrent-rutorrent-openvpn
    cap_add:
    - NET_ADMIN
    expose:
    - "80/tcp"
    ports:
    - 49161:49161
    volumes:
    - ./downloads/complete:/home/rtorrent/downloads/complete
    - ./downloads/incomplete:/home/rtorrent/downloads/incomplete
    - ./session:/home/rtorrent/session
    - ./watch:/home/rtorrent/watch
    - ./plugins:/var/www/rutorrent/plugins
    - ./themes:/var/www/rutorrent/themes
    - ./vpn:/home/rtorrent/vpn
    environment:
    - VPN_EXCLUDE_NETWORK=172.0.0.0
    - DNS_SERVER_IP=nnn.nnn.nnn.nnn
    - PHP_MEM=256M
    restart: unless-stopped

##Environment variables

• VPN_EXCLUDE_NETWORK: (Default empty) Network to exclude from being sent through the VPN, useful when accessing container from a reverse proxy (recommended setup).
• DNS_SERVER_IP: (Default: 8.8.8.8) Address for DNS Server of your choice.
• PHP_MEM: (Default: 256M) Memory allocated for PHP.
• UID: (Default: 991) UserID used for running the service.
• GID: (Default: 991) GroupID used for running the service.

##Volumes

Your volumes ownership must match the one used by this container services (default to 991:991).

Your personal OpenVPN configuration files should be stored in /home/rtorrent/vpn. They will be automatically loaded and properly routed. The configuration files for the openvpn must end in ovpn. This is because startup calls openvpn --config *.ovpn

The XML RPC url is: /RPC2
