EK DNS netpol does not allow port 5353 for Openshift
Bug
Description
Attempting to deploy a fresh bigbang 1.11.0, all the logging-ek-* pods fail to come up. I was able to find this error in the elasticsearch container logs:
BindTransportException[Failed to resolve publish address]; nested: UnknownHostException[logging-ek-es-data-0.logging-ek-es-data.logging.svc: Name or service not known]; Likely root cause: java.net.UnknownHostException: logging-ek-es-data-0.logging-ek-es-data.logging.svc: Name or service not known
Openshift version 4.6.4
Found that removing all network policies in the logging namespace allows all the pods to come up succesfully.
BigBang Version
1.11.0
