Odoo is a complete ERP system which runs on Python and PostgreSQL. It's a fairly large application and it would be amazing to be able to create Odoo droplets in Digital Ocean. There are Docker images available for Odoo as well as basic installation. It runs flawlessly on Ubuntu 1404.
I currently have to use Amazon AWS which is good of course, but I prefer my favorite, Digital Ocean.
A starting point could be to check out how others are offering it.
