What is a good firewall that can also block ports published with docker? I'd need it to run on the same host.

UFW does work with Docker, but requires some tweaking. IIRC you have to disallow Docker to modify IPTables and then add a rule to forward all traffic to the Docker network of your choice. It's a little finicky but works.

Interesting, I might have to read up on that next time. Thanks

I ran into this same situation, this repo helped me solve it.
