$ oc login https://api.ci.openshift.org --token=<token value>
$ docker login -u <docker user id> -p $(oc whoami -t)  registry.svc.ci.openshift.org
$ oc adm release info --commits registry.svc.ci.openshift.org/ocp/release:4.2.0-0.nightly-2020-05-26-002810 | grep kube-apiserver

$ git log --date local --pretty="%h %an %cd - %s" 1224485 | grep '#724'

No results

The fix was not in latest OCP 4.2 payload. Waiting for the next.

Comment 4 Ke Wang 2020-05-27 02:31:04 UTC
Verified with OCP build 4.2.0-0.nightly-2020-05-26-081314.

Verification steps referring to the code changes from PR https://github.com/openshift/cluster-kube-apiserver-operator/pull/724

1. Check the apiserver pods information, 
$ apiserver_pod=$(oc get po -n openshift-kube-apiserver | grep kube-apiserver | awk '{print $1}' | head -1)

$ oc get po $apiserver_pod -n openshift-kube-apiserver -o json | jq .spec.initContainers[0].securityContext
  "privileged": true
$ oc get po $apiserver_pod -n openshift-kube-apiserver -o json | jq .spec.containers[0].securityContext
  "privileged": true

The containers' securityContext were changed.

2. Check if the related error ‘failed to tryAcquireOrRenew’ can be found.
$ apiserver_node=$(oc get po -o wide -n openshift-kube-apiserver | grep kube-apiserver | awk '{print $7}' | head -1)
$ oc debug node/$apiserver_node

After logged in  the debug pod of the apiserver node , 
sh-4.2# chroot /host

sh-4.4# grep -r 'failed to tryAcquireOrRenew' /var/log/pods/openshift-kube-apiserver_kube-apiserver-*/

No results, not found the related error ‘failed to tryAcquireOrRenew’ . It is as expected, move the bug verified.
