How to use Ubuntu 14.04 on AWS Elastic Beanstalk for a Python Django app

I want to ensure that the development environment to work just the same as the production environment. This is to minimise "it works for me" finger-pointing.

Hence my team chose Ubuntu 14.04 as the operating system.

We also want to deploy on AWS.

As I was running through the QwikLabs example on using Elastic Beanstalk, I realized that there is no choice to select Ubuntu 14.04.

How do I go about deploying a Django app on a AWS EC2 instance that is running on Ubuntu 14.04?

Thank you.
