The idea: - all nodes generate their config in /etc/nginx/node.conf.d/HOSTNAME.conf - a python script can read all configs and merge them into one and reload nginx - using entr in Procfile, anytime any of these config change, they are merged immediately - the default nginx reload on notify is being removed to prevent from reloading twice
