doesn't docker have this weird property where it bypasses your firewall? https://www.techrepublic.com/article/how-to-fix-the-docker-and-ufw-security-flaw/ http

  What about second firewalls ? Hobbit jokes aside, yes, it pokes holes in the firewall on the machine hosting docker. It generally creates a lot of firewall rules to isolate or permit traffic to/from containers and expose ports. Your "safest" bet is probably to only expose docker containers on the localhost interface, and use a reverse proxy (Nginx/Traefik/etc) to expose services. At least that's how i did it when i last ran Docker a few years ago.
