Docker VPN

Docker based vpn openvpn server with dnsmasq.

The idea here is to make vpn server install and management easy to use on top of docker. Docker is not required to run openvpn, but it makes encapsulation easier if we want to have multiple networks on one host. Also comes with built-in dnsmasq server, that makes your life easier when you want to set up internal domain names for the office or in similar use cases.

Notes

• Works only on linux hosts.
• Uses /var/lib/docker/volumes to add files to the vpn volumes

The docker image can be used standalone.

The vpn command has an alias docker-vpn, if the word vpn is already in use

The npm package makes it easy to use it all without having to remember commands.

Install node

curl -sL https://deb.nodesource.com/setup_14.x | sudo -E bash -; sudo apt-get install -y nodejs

Install docker-vpn

npm install -g docker-vpn
vpn --help # If the vpn command is busy, use docker-vpn

For Ubuntu/Debian distributions:

vpn install-dependencies

For other distributions you will need to install:

curl
docker-ce/ee
docker-compose

Known issues

• Revoking clients requires restart. Not sure why, it must not behave this way, but...
• Windows users have to remove the linux lines at the end of the config file.

TODO

• Install scripts for other linux distros
• Autocomplete commands when double tab is pressed
