This is a small set of docker containers hosting a load-balancer and
web_apps written in ruby

it was inspired by

https://github.com/Muriel-Salvan/rails-cluster-docker

It uses Docker links, and the proxy.rb script simply harvests the /etc/hosts
file to find out which 'servers' it should proxy.

It also uses sinatra to serve the web app instead of a full blown rails app
