OpenVPN Docker Image

There is already an existing docker-image for openvpn created by (kylemanna/docker-openvpn)[https://github.com/kylemanna/docker-openvpn] - With over 180 issues, 40 open PR's and last commit done in March 2020 I decided to tread this image as not maintained anymore, also It was a good way for me to make myself more familiar with building and setting up docker images so that's why I created my own.

Most of its documentation can be found in the root directory, if you want to run it without anything else you'll have to edit the dns-configuration (which currently points to the PiHole DNS Server) and if you don't want to use a custom dns-resolve at all, you may also want to comment out this line.

Run this image using docker itself

First, build the image:

sudo docker build -t openvpn .

Run the image:

sudo docker run openvpn \
    --expose 1194:1194/udp \
    --mount type=bind,src=./openvpn/pki,dst=/etc/openvpn/pki \
    --mount type=bind,src=./openvpn/clients,dst=/etc/openvpn/clients \
    --mount type=bind,src=./openvpn/config,dst=/etc/openvpn/config \
    --cap-add=NET_ADMIN \
    --restart=unless-stopped

Run this image using a docker-compose.yml file

services:
    openvpn:
        container_name: openvpn-tcp-443
        build: ./openvpn-docker
        ports:
            - 1194:1194/udp
        volumes:
            - ./openvpn/pki:/etc/openvpn/pki # Directory with our public key infrastructure
            - ./openvpn/clients:/etc/openvpn/clients # .ovpn files
            - ./openvpn/config:/etc/openvpn/config # server.conf and client.conf should both be in there
        cap_add:
            - NET_ADMIN
        restart: unless-stopped
# ... other services
