## Django and Docker

Docker implements operating-system-level virtualization, otherwise known as containerization.
Containers are great for development and production because they allow for easier reproduce-ability.
In this class you will learn how to use docker to run a Django web application as well as the common
local development and production setups of a web application and
some tips to use Django and Docker together.

### Pre-requisites:

1. Python 2.7+, preferred Python 3.x.
2. Install Docker (Community Edition CE or Enterprise is OK):
1. Mac: https://docs.docker.com/docker-for-mac/install/

2. Debian: https://docs.docker.com/install/linux/docker-ce/centos/
3. Fedora: https://docs.docker.com/install/linux/docker-ce/fedora/
4. Ubuntu: https://docs.docker.com/install/linux/docker-ce/ubuntu/
5. Binaries: https://docs.docker.com/install/linux/docker-ce/binaries/
3. Windows: https://docs.docker.com/docker-for-windows/install/
3. Install docker-compose:
1. Mac: If you followed the link above docker-compose should already be installed in your system.
