Iptable manipulation in Docker for Mac

docker

(Jsonai) #1

I want to disable all outgoing connections that are initiated by docker containers to the outside world. I can do this in linux by adding a rule to the FORWARD chain in linux. How do I do this in Docker for Mac?

I found out that Docker for Mac uses an xhyve vm and that’s where docker0 interface lives. What interface in the host does this connect to? I used nettop on Mac and I see that Docker uses my en0 wireless interface. But, I’m not sure if Docker and xhyve are using the same interface.

Thanks,
Jay
