This is a basic summary of excellent tutorial from Digital Ocean on how to setup OpenVpn with Docker.

1. Create an fqdn

I am using AWS Route53 for this step so when you login create an A record(assuming you are pointing to an ip.) for your vpn. Assuming your domain name is yourdomain.com, create something like vpn.yourdomain.com

2. Create a data container.

export OVPN_DATA="ovpn-data"

docker run -name $OVPN_DATA -v /etc/openvpn busybox

3. Generate vpn config file based on fqdn.

docker run --volumes-from $OVPN_DATA --rm kylemanna/openvpn ovpn_genconfig -u udp://vpn.yourdomain.com:1194

4. Generate ovpn_initpki

docker run --volumes-from $OVPN_DATA --rm -it kylemanna/openvpn ovpn_initpki

5. Run the server

docker run --volumes-from $OVPN_DATA --rm -p 1194:1194/udp --cap-add=NET_ADMIN kylemanna/openvpn

6. Generate client keys

docker run --volumes-from $OVPN_DATA rm -it kylemanna/openvpn easyrsa build-client-full serkan nopass

docker run --volumes-from $OVPN_DATA -rm kylemanna/openvpn ovpn_getclient serkan > serkan.ovpn

7. Run the server

docker run -d --volumes-from $OVPN_DATA -p 0.0.0.0:1194:1193/udp --cap-add=NET_ADMIN kylemanna/openvpn
