#  * $HOME_APP_ROOT - Root directory of application
#  * $NPM_RUN - Select an alternate / custom runtime mode, defined in your package.json file's scripts section (default: npm run "start").
#               These user-defined run-scripts are unavailable while DEV_MODE is in use.
# Exposed ports:
# * 8080 - Unprivileged port used by nodejs application
# Additional packages
#  * findutils are needed to help fix permissions.
