1. Define volume name variable

OVPN_DATA="docker-openvpn_ovpn-data"

2. Create the volume

docker volume create --name $OVPN_DATA

3. Generate configuration

(It will ask for a phase to define keys. You can use any type of word)

docker-compose run -v $OVPN_DATA:/etc/openvpn --rm vpn ovpn_genconfig -u udp:https://vpn.dummydomain.click

docker-compose run -v $OVPN_DATA:/etc/openvpn --rm vpn ovpn_initpki

• This is goign to ask for phrase key. Put whatever phrase you want.
• Then is going to ask for the host name, Type in the domain you have setup for this server (vpn.dummydomain.click)

4. Generate client files

docker-compose run -v $OVPN_DATA:/etc/openvpn --rm vpn easyrsa build-client-full CLIENTNAME nopass

docker-compose run -v $OVPN_DATA:/etc/openvpn --rm vpn ovpn_getclient CLIENTNAME > CLIENTNAME.ovpn

This last command is going to generate the client configuration file that will allow you to connect from your PC or mobile device. The fle gets created in the same directory from where you are executing it.
