The current plan is to expose this information through YARN service because
YARN service AM can aggregate container information.

> Add port mapping handling when docker container use bridge network
> ------------------------------------------------------------------
>
> Key: YARN-5168
> URL: https://issues.apache.org/jira/browse/YARN-5168
> Project: Hadoop YARN
> Issue Type: Sub-task
> Reporter: Jun Gong
> Assignee: Eric Yang
> Priority: Major
> Labels: Docker
>
> YARN-4007 addresses different network setups when launching the docker
> container. We need support port mapping when docker container uses bridge
> network.
> The following problems are what we faced:
> 1. Add "-P" to map docker container's exposed ports to automatically.
> 2. Add "-p" to let user specify specific ports to map.
> 3. Add service registry support for bridge network case, then app could find
> each other. It could be done out of YARN, however it might be more convenient
> to support it natively in YARN.
