Forked from ekristen. Add automated multi archbuilds and tags for OpenVPN version in Alpine. Check out jnovack/docker-multi-arch-hooks for that.

Docker OpenVPN Client

1. You should add the generated openvpn client config to a directory, you can call it client.ovpn
2. You should add the password for the private key in the client.ovpn to client.pwd
3. Run the following, I recommend adding --auth-nocache

docker run -d --name vpn-client \
  --cap-add=NET_ADMIN \
  --device /dev/net/tun \
  -v /path/with/vpn/configs:/vpn \
  frauhottelmann/openvpn-client:tag --config /vpn/client.conf --askpass /vpn/client.pwd --auth-nocache

Route container traffic

Use --net=container:<container-id> -- routes available by the VPN client will be made available to the container.

docker run -it --rm \
  --net=container:vpn-client
  ubuntu /bin/bash

docker-compose example:

version: '3'

services:
  openvpn-client:
    image: frauhottelmann/openvpn-client
    container_name: openvpn-client
    restart: always
    cap_add:
      - NET_ADMIN
    devices:
      - "/dev/net/tun:/dev/net/tun"
    command: --config /vpn/client.ovpn --askpass /vpn/client.pwd --auth-nocache
    volumes:
      - ./client/:/vpn
    network_mode: "bridge"
