The Setup

This is a docker-compose file for a simple, secure torrent setup. It includes [rTorrent] (a torrent client), [flood] (a web interface for rTorrent), [OpenVPN] (to tunnel traffic through your ISP) and a simple iptables firewall to allow rTorrent to only access the internet through a VPN.

To run everything, put your open vpn configuration file in ./vpn.ovpn and the other configuration files from this gist in a directory then go to that
