Quick Docker container setup

Create a Dockerfile for the web application and it’s dependencies and a Docker Compose file describing a database and a webserver as well as the web application itself. The web app should talk to a standalone database, preferably Mysql or Postgres, as opposed to the default sqlite local file-based database. The application itself should talk to the standalone database and sit behind a web server. This will require changing the Django settings file so the database can be configured to talk to the standalone database. You will also need to link all of the containers up in the [login to view URL] file. We would prefer you use Nginx for the web server, but if you know another technology that would fit better, feel free to use it. You may use community docker images for the web server and database server, but we would like you to write the Dockerfile for the web application.  ## Project Deliverables * Changes to the settings file* Any files required for building or dependency management * A Dockerfile for building the web application docker image * A [login to view URL] file that can be used to spin up the app/web server/database as a cluster. We should be able to build the cluster by just issuing `docker-compose up`.
