What I don't like about Docker is it does not respect the firewall rules that I setup using something like ufw.

Docker doesn't change iptables as set up by ufw. do you have more info on your issue?

[bananadonkey]

Docker does add iptables rules by default, which bypass other rules such as those you might set with ufw.

https://github.com/chaifeng/ufw-docker has a good overview and ufw-specific solution (I use it on my rpi).
