# The NGINX daemon allows NGINX to run in background mode. This is great for most applications. \
#   However, in Docker, when the NGINX service gets shifted to the background, the Docker       \
#   daemon interprets this as its ENTRYPOINT script coming to an end. This causes Docker to shut\
#   down the container early. To fix this, we run NGINX in the foreground.                      \
#   The docker-entrypoint.sh file is provided by the nginx parent container and is maintained by\
#   NGINX Docker Maintainers. https://hub.docker.com/_/nginx
