In 4.5.0-0.nightly-2020-04-03-003232 service-ca-operator log also has same issue:

$ oc logs service-ca-operator-66c57bf95f-gbb9d -n openshift-service-ca-operator | grep 'configmap "extension-apiserver-authentication" not found'

W0403 07:20:08.246735       1 configmap_cafile_content.go:102] unable to load initial CA bundle for: "client-ca::kube-system::extension-apiserver-authentication::client-ca-file" due to: configmap "extension-apiserver-authentication" not found

To verified if the log occurred the pod starting up, tried the following,

$ oc delete pod service-ca-operator-66c57bf95f-gbb9d -n openshift-service-ca-operator --force --grace-period=0
warning: Immediate deletion does not wait for confirmation that the running resource has been terminated. The resource may continue to run on the cluster indefinitely.

$ oc get pods -A |grep service-ca-operator
openshift-service-ca-operator                      service-ca-operator-66c57bf95f-wzqf5                                 1/1     Running     0          20s

$ oc logs service-ca-operator-66c57bf95f-wzqf5 -n openshift-service-ca-operator | grep 'configmap "extension-apiserver-authentication" not found'

We can see the above message will be printed at the pod startup.

It is an issue worth to address. To avoid similar problem just like https://bugzilla.redhat.com/show_bug.cgi?id=1813911

Comment 1 Ke Wang 2020-04-03 09:28:36 UTC

Another related pod also has the same problem,

Comment 8 Ke Wang 2020-05-12 04:28:05 UTC

Verified with OCP build 4.5.0-0.nightly-2020-05-11-225223,

$ oc delete pod service-ca-operator-68bf9c867-4zsv6 -n openshift-service-ca-operator --force --grace-period=0
warning: Immediate deletion does not wait for confirmation that the running resource has been terminated. The resource may continue to run on the cluster indefinitely.
