Docker - OpenVPN

Installation

1. Pick a name for the $OVPN_DATA data volume container. It's recommended to use the ovpn-data- prefix to operate seamlessly with the reference systemd service. Users are encourage to replace example with a descriptive name of their choosing.

   OVPN_DATA="ovpn-data-example"

2. Initialize the $OVPN_DATA container that will hold the configuration files and certificates. The container will prompt for a passphrase to protect the private key used by the newly generated certificate authority. Remplace VPN.SERVERNAME.COM by an IP address or a server name.

   docker volume create --name $OVPN_DATA
   docker run -v $OVPN_DATA:/etc/openvpn --rm kylemanna/openvpn ovpn_genconfig -u udp://VPN.SERVERNAME.COM
   docker run -v $OVPN_DATA:/etc/openvpn --rm -it kylemanna/openvpn ovpn_initpki

3. Start OpenVPN server process

   docker run -v $OVPN_DATA:/etc/openvpn -d -p 1194:1194/udp --cap-add=NET_ADMIN kylemanna/openvpn

4. Generate a client certificate without a passphrase. Remplace CLIENTNAME by the name of the user.

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

5. Retrieve the client configuration with embedded certificates. Remplace CLIENTNAME by the name of the user.

   docker run -v $OVPN_DATA:/etc/openvpn --rm kylemanna/openvpn ovpn_getclient CLIENTNAME > CLIENTNAME

6. Copy you opvn configuration file to your client host. For Windows you can use the SCP command described here Powershell - SCP
