Create a Docker Network Namespace

docker network create dkrnet

Create Network Folders on the Host for Configuration and Logs

The example below will assume you have the following folders created:

/home/$USER/ipop/config
/home/$USER/ipop/log/drk001

And that a valid IPOP configuration file is stored in:

/home/$USER/ipop/config/config-001.json

Run the Container

docker run -d -v /home/$USER/ipop/config/config-001.json:/etc/opt/ipop-vpn/config.json -v /home/$USER/ipop/log/drk001:/var/log/ipop-vpn/ -v --rm --privileged --name ipop-dkr001 --network dkrnet ipopproject/ipop-vpn:1.0 /sbin/init

Test the Container

You should then be able to log in to the container and check it obtained an IPOP virtual network address (naturally, your Docker container ID and IP addresses will be different from what you see below):

docker exec -it ipop-dkr001 /bin/bash
