[jira] [Created] (YARN-7797) Docker host network can not obtain IP address for RegistryDNS

Eric Yang created YARN-7797:
-------------------------------

             Summary: Docker host network can not obtain IP address for RegistryDNS
                 Key: YARN-7797
                 URL: https://issues.apache.org/jira/browse/YARN-7797
             Project: Hadoop YARN
          Issue Type: Sub-task
          Components: nodemanager
    Affects Versions: 3.1.0
            Reporter: Eric Yang


When docker is configured to use host network, docker inspect command does not return IP address of the container.  This prevents IP information to be collected for RegistryDNS to register a hostname entry for the docker container.

The proposed solution is to intelligently detect the docker network deployment method, and report back host IP address for RegistryDNS.
