where are the artifacts for that run? I can't navigate from the link you put there.


RC deployment-simple-2 has only 2 of 3 replicas available

pod deployment-simple-2-5b89l was created at "2019-09-04T22:54:38Z" and started at "2019-09-04T22:54:41Z" ready at "2019-09-04T22:54:51Z"

pod deployment-simple-2-txtb8 was created at "2019-09-04T22:55:02Z" and started at "2019-09-04T22:55:05Z" ready at "2019-09-04T22:55:15Z"

pod deployment-simple-2-x8q4q was created at "2019-09-04T22:55:02Z" and started at "2019-09-04T22:55:05Z" ready at "2019-09-04T22:55:07Z"

it saw the scaling event at
INFO: At 2019-09-04 22:55:02 +0000 UTC - event for deployment-simple: {deploymentconfig-controller } ReplicationControllerScaled: Scaled replication controller "deployment-simple-2" from 1 to 3

and was already gathering data at Sep  4 22:55:32.566 but it must have not checked since "2019-09-04T22:55:15Z" when the last pod became ready.

timing is close for where the previous RC was deleted and the new one created. I think I saw something similar reported for RS (which shares almost the same code) in upstream.

controller logs would be helpful though

I think this is broken RS, fix in https://github.com/kubernetes/kubernetes/pull/82572
