# This is written so compact, to reduce the size of the final container
# and its layers. We have to install build dependencies, build the app,
# deploy the app to the web root, remove the source code, and 
# then uninstall the build dependencies. When packed into one RUN
# instruction, the resulting layer will only be comprised of the
# installed app artifacts.
