Eric Yang commented on YARN-5168:
---------------------------------

[~liuxun323] This jira is to aggregate the information and save in 
ContainerStatus.  YARN service will automatically include this information in 
yarn app -status call.  [~Charo Zhang] is already working on YARN-8986 to add 
-P to docker run.

> Add port mapping handling when docker container use bridge network

> 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.
