Accessing docker container from Docker for Mac

Question

I have the following scenario:

• Mac OS Catalina
• Windows Virtual Machine running on VirtualBox
• Docker for Mac (not docker-machine or Docker Toolbox)

I need to access a port that is exposed with docker run -p 80:80 nginx from the Windows VM and nothing seems to work. I tried NAT, bridge, socat... any hints?

Answer 1

Ah, I figured it out. I can access the docker service by using the bridge interface IP (but not using localhost). So in essence:

• VM in VirtualBox should run in network bridged mode
• use http://1.2.3.4 in the browser where 1.2.3.4 is your MacOS network interface IP address
