# This adds everything we need to the build root except those
# element that are matched by .dockerignore.
# We explicitly list every directory and file that is involved
# in the build process but. All config files (like nginx) are
# not listed to speed up the build process.

# 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 hopefully only be comprised of the
# installed app artifacts.
