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.
