Verified with OCP build: 4.3.0-0.nightly-2020-03-03-144847 1. Check if the bug related PR has been already merged in current release. $ oc adm release info --commits registry.svc.ci.openshift.org/ocp/release:4.3.0-0.nightly-2020-03-03-144847 | grep 'kube-scheduler-operator' cluster-kube-scheduler-operator https://github.com/openshift/cluster-kube-scheduler-operator f50817dfacbd8a90ffa9a5ba53cfdbf27bcc243a $ git checkout -b 4.3.0-0.nightly-2020-03-03-144847 f50817df $ git log --pretty="%h %an %cd - %s" f50817df | grep bump-library-go-43 f50817df OpenShift Merge Robot Thu Feb 20 02:52:39 2020 +0100 - Merge pull request #210 from mfojtik/bump-library-go-43 We can see the PR already in. 2. Installed the OCP build on GCP platform and check if a panic can be observed in kube-apiserver-operator log, Refer to https://bugzilla.redhat.com/show_bug.cgi?id=1774212#c0, did the following checking, $ oc logs -n openshift-kube-apiserver-operator kube-apiserver-operator-6b98fdd948-l9qhh > kube-apiserver-operator.log $ grep -n -E 'Starting BackingResourceController|Starting UnsupportedConfigOverridesController' kube-apiserver-operator.log 28:I0304 11:30:47.647446 1 backing_resource_controller.go:138] Starting BackingResourceController 29:I0304 11:30:47.647465 1 unsupportedconfigoverrides_controller.go:151] Starting UnsupportedConfigOverridesController $ grep -n 'panic' ./kube-apiserver-operator.log Not found any panic error.
Checked openshift-kube-scheduler-operator logs, the result is as expected in the following, $ oc logs -n openshift-kube-scheduler-operator openshift-kube-scheduler-operator-6796b47dbd-lkz5p > openshift-kube-scheduler-operator.log $ grep -n -E 'Starting BackingResourceController|Starting UnsupportedConfigOverridesController' ./openshift-kube-scheduler-operator.log 21:I0305 09:01:17.639833 1 backing_resource_controller.go:138] Starting BackingResourceController 22:I0305 09:01:17.639874 1 unsupportedconfigoverrides_controller.go:151] Starting UnsupportedConfigOverridesController $ grep -n 'panic' ./openshift-kube-scheduler-operator.log Not found any panic error.
