We can map docker container port to host machine IP and port using 

docker run -d -p <some-ip>:<port>:<port> --name <some-name> <docker-image>

But how to specify host machine IP while deploying the same container using Marathon? Where should I specify the IP of host machine in Marathon app spec? For my requirement specifying host IP is a necessity.

You can use Marathon constraints to influence the placement of your app but I'd suggest that a better, more forward-looking way is not to pin an app to a certain node (what if this node fails?) but use service discovery to dynamically figure out the IP and the port the app is serving on.

  • What if I deploy my docker container using host mode and not the bridge mode? What aspects of running container would and wouldn't be isolated from the host machine in that case? – t6nand May 14 '16 at 10:35
  • And, @t6nand: if you have additional questions, start a new one. This tagging onto an existing question is bad and not useful for people coming after you. – Michael Hausenblas May 14 '16 at 10:55
