Peas is a Heroku-style Platform as a Service written in Ruby using Docker. It is heavily inspired by Deis and Dokku. Peas' philosophy is to be an accessible and easily hackable PaaS. It doesn't aim to be a complete enterprise solution. Instead it aims to be a relatively unopinionated, but solid starting place using all the goodness of Ruby; Rspec, Bundler, Guard, Rack, Mongoid, Docker-api, Puma, Grape, GLI, Celluloid, and more.
