Dockerfile

# Dockerfile for a Django Application for querying Oregon campaign data as part of the Hack Oregon project
# More info on the project at http://totalgood.github.io/hackor/
# This container has no external dependencies and should automatically run the application when started

# Note: this is a terrible example of how Dockerfiles should be written
# Normally one should not combine the database and the app in the same container,
# nor should the data be baked into the container.
# This is special case to help develop and run the demo app.

# Stat with a bloated but useful Ubuntu linux image
FROM ubuntu:15.10
