qBittorrent with WebUI and OpenVPN

Docker container which runs the latest headless qBittorrent client with WebUI while connecting to OpenVPN with iptables killswitch to prevent IP leakage when the tunnel goes down.

Docker Features

• Base: Ubuntu 20.04
• Always builds latest qBittorrent client
• Size: 300MB
• Selectively enable or disable OpenVPN support
• IP tables kill switch to prevent IP leaking when VPN connection fails
• Specify name servers to add to container
• Configure UID, GID, and UMASK for config files and downloads by qBittorrent
• WebUI\CSRFProtection set to false by default for Unraid users

Run container from Docker registry

The container is available from the Docker registry and this is the simplest way to get it. To run the container use this command:

$ docker run --privileged  -d \
              -v /your/config/path/:/config \
              -v /your/downloads/path/:/downloads \
              -e "VPN_ENABLED=yes" \
              -e "LAN_NETWORK=192.168.1.0/24" \
              -e "NAME_SERVERS=8.8.8.8,8.8.4.4" \
              -p 8080:8080 \
              -p 8999:8999 \
              -p 8999:8999/udp \

Variables, Volumes, and Ports

Environment Variables

Variable	Required	Function	Example
VPN_ENABLED	Yes	Enable VPN? (yes/no) Default:yes	VPN_ENABLED=yes

VPN_PASSWORD	No	If username and password provided, configures ovpn file automatically	VPN_PASSWORD=ac98df79ed7fb
LAN_NETWORK	Yes	Local Network with CIDR notation	LAN_NETWORK=192.168.1.0/24
NAME_SERVERS	No	Comma delimited name servers	NAME_SERVERS=8.8.8.8,8.8.4.4
PUID	No	UID applied to config files and downloads	PUID=99
PGID	No	GID applied to config files and downloads	PGID=100
UMASK	No	GID applied to config files and downloads	UMASK=002
WEBUI_PORT_ENV	No	Applies WebUI port to qBittorrents config at boot (Must change exposed ports to match)	WEBUI_PORT_ENV=8080
INCOMING_PORT_ENV	No	Applies Incoming port to qBittorrents config at boot (Must change exposed ports to match)	INCOMING_PORT_ENV=8999

Volumes

Volume	Required	Function	Example
config	Yes	qBittorrent and OpenVPN config files	/your/config/path/:/config
downloads	No	Default download path for torrents	/your/downloads/path/:/downloads

Ports

Port	Proto	Required	Function	Example
8080	TCP	Yes	qBittorrent WebUI	8080:8080
8999	TCP	Yes	qBittorrent listening port	8999:8999
8999	UDP	Yes	qBittorrent listening port	8999:8999/udp

Access the WebUI

Access http://IPADDRESS:PORT from a browser on the same network.

Default Credentials

Credential	Default Value
WebUI Username	admin
WebUI Password	adminadmin

Origin header & Target origin mismatch

WebUI\CSRFProtection must be set to false in qBittorrent.conf if using an unconfigured reverse proxy or forward request within a browser. This is the default setting unless changed. This file can be found in the dockers config directory in /qBittorrent/config

WebUI: Invalid Host header, port mismatch

qBittorrent throws a WebUI: Invalid Host header, port mismatch error if you use port forwarding with bridge networking due to security features to prevent DNS rebinding attacks. If you need to run qBittorrent on different ports, instead edit the WEBUI_PORT_ENV and/or INCOMING_PORT_ENV variables AND the exposed ports to change the native ports qBittorrent uses.

How to use OpenVPN

The container will fail to boot if VPN_ENABLED is set to yes or empty and a .ovpn is not present in the /config/openvpn directory. Drop a .ovpn file from your VPN provider into /config/openvpn and start the container again. You may need to edit the ovpn configuration file to load your VPN credentials from a file by setting auth-user-pass.

Note: The script will use the first ovpn file it finds in the /config/openvpn directory. Adding multiple ovpn files will not start multiple VPN connections.

Example auth-user-pass option

auth-user-pass credentials.conf

Example credentials.conf

username
password

PUID/PGID

User ID (PUID) and Group ID (PGID) can be found by issuing the following command for the user you want to run the container as:

id <username>

Issues

If you are having issues with this container please submit an issue on GitHub. Please provide logs, docker version and other information that can simplify reproducing the issue. Using the latest stable verison of Docker is always recommended. Support for older version is on a best-effort basis.

Building the container yourself

To build this container, clone the repository and cd into it.

Build it:

$ cd /repo/location/qbittorrentvpn
$ docker build -t qbittorrentvpn .

Run it:

$ docker run --privileged  -d \
              -v /your/config/path/:/config \
              -v /your/downloads/path/:/downloads \
              -e "VPN_ENABLED=yes" \
              -e "LAN_NETWORK=192.168.1.0/24" \
              -e "NAME_SERVERS=8.8.8.8,8.8.4.4" \
              -p 8080:8080 \
              -p 8999:8999 \
              -p 8999:8999/udp \
              qbittorrentvpn

This will start a container as described in the "Run container from Docker registry" section.
