• How to get the IP address of the docker host from inside a docker container 15 answers

I need to setup a debugger on my container, that requires me to set the remote (docker host) IP. In different tutorials I find different IP addresses listed as possible solution. In my container I ran a webserver that showed me that connections made to the container from my host machine come from 172.19.0.1. This is on Docker for Mac version 1.11.x.

But how would I reliably find out the host IP as seen from the container on Docker for Mac? When would it be possible for this IP to change?

You can get the ip of the host from within the container by running this command:

/sbin/ip route|awk '/default/ { print $3 }'
