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.
But…why?
Project Calico is designed for segmenting network traffic between kubernetes workloads.
Right tool for the job.
Also if you are a Fortinet shop, supposedly you can manage rules with FortiManager. I haven’t tried that yet but it looks really cool.
I was specifically talking about Docker+UFW. Of course the possibilities are endless.
