Dockerfile_from_scratch

# Generate a fresh Docker image containing all the dependencies that
# we need to run the web app (and manage it over SSH).
#
# Usage:
#   docker build . -f Dockerfile_from_scratch -t penelopeysm/apribot && docker push penelopeysm/apribot
#
# After this is done, the main Dockerfile will just pull from this pre-built
# image, meaning that we don't have to re-build the dependencies every time we
# deploy.
