Docker-compose with ufw-docker in Ubuntu 20.04
Problem During development using docker-compose on Ubuntu, I realized something weird was happening with my UFW. It just did not work as it should. Publishing ports in docker-compose just overrid any UFW settings, and I was no longer able to use UFW to control the traffic. You could say that if you expose a port, the purpose is to keep it open, but sometimes I still want to use a firewall to open/close port access, without disturbing the running services....
