Fixed In Version: Doc Type: Bug Fix
Doc Text:
Cause: OpenShift was treating a non-error situation as an error Consequence: Multiple error messages of the form "PodIP is not set for pod ..." might be logged on a node each time a new pod started, when using the networkpolicy plugin. (The actual functioning of NetworkPolicy was not affected; the bug is solely that spurious messages were logged.) Fix: The message is now logged at a lower level. Result: Clusters with standard --loglevel values will no longer see this message.

Version-Release number of selected component (if applicable):
v3.7.0-0.150.0

How reproducible:
always

Steps to Reproduce:
1. Setup multi node env with network policy plugin
2. Try to create pod on the env
3. Check the node log during the pod creation

Actual results:
There are lots of warnings about the podip is not set.


Expected results:
To avoid the warning, we should either check the pod status later when the pod is already running or reduce the frequency if we have to check before pod running.
