OpenVPN Docker Mod

An s6 v3 docker-mod for LinuxServer.io containers that establishes an OpenVPN connection on container startup.

Usage

To use this mod, add the following environment variables to your LinuxServer.io container:

In docker arguments, set an environment variable DOCKER_MODS=ghcr.io/eshork/universal-openvpn:latest to enable.

If adding multiple mods, enter them in an array separated by |, such as DOCKER_MODS=user/repo:tag|user/repo:tag

Settings

Environment variables

  • OVPN_CONFIG: Full path to the OpenVPN configuration file to use. Default is /etc/openvpn/config. (Provide this file to your container as a volume mount.)
  • OVPN_CREDENTIALS: Full path to the credentials file to pass via --auth-user-pass. Default is /etc/openvpn/credentials. If not present, will not pass credentials. (Provide this file to your container as a volume mount.)
  • OVPN_KILLSWITCH: If set to true or 1, will implement a route-based traffic kill switch, attempting to prevent traffic leaking beyond your local network when the VPN tunnel is down.
  • OVPN_SPLIT_PRIVATE: If set to true or 1, will inject routes to preserve access to private network addresses (RFC1918) via the initial default route. Default is false.
  • OVPN_HALT_ON_FAILURE: If set to true or 1, will issue halt command to stop the container if the OpenVPN connection is lost or could not be established. Default will not attempt to stop the container.
  • OVPN_OPTS_ADD: Additional options to append to the openvpn command. Default is empty.
  • OVPN_OPTS_OVERRIDE: If set, will completely override the generated openvpn command arguments with the provided value. This is useful for advanced users who want full control over the openvpn command arguments, but is often not necessary. Default is empty.

ONLY TESTED ON AN ALPINE BASED CONTAINER
