I see lots of events like: Pod Warning DNSSearchForming kubelet, ip-172-31-52-130.ec2.internal Found and omitted duplicated dns domain in host search line: 'cluster.local' during merging with cluster dns domains 1 pod is showing these events more than once per second. Do we need these at all? Should they be rate limited? (are they?) Is this a misconfiguration of some sort?
*** Bug 1471197 has been marked as a duplicate of this bug. ***
Upstream PR: https://github.com/kubernetes/kubernetes/pull/48960
The rate limiting work we are carrying in Origin pending: https://github.com/kubernetes/kubernetes/pull/47367 will make a major improvement to the rate of events in this case. This event serves the cluster operator more than the cluster end-user. Agree it should be removed.
