@sburnwal but docker host is the gateway, isn't it? In what kind of config is docker host not the gateway of docker containers?
Note that if your host is Mac, the 172.17.0.1 will be a wrong answer. Use dedicated DNS name docker.for.mac.localhost instead.

This gives the gateway ip and not the docker host ip.
