# Runtime command that executes when "docker run" is called, it does the
# following:
#   1. Migrate the database.
#   2. Start the application server.
# WARNING:
#   Migrating database at the same time as starting the server IS NOT THE BEST
#   PRACTICE. The database should be migrated manually or using the release
#   phase facilities of your hosting platform. This is used only so the
#   Django instance can be started with a simple "docker run" command.
