To verified if the log occurred the pod starting up, tried the following, $ oc delete pod oauth-openshift-56d45f4dc6-gf8vb -n openshift-authentication --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. pod "oauth-openshift-56d45f4dc6-gf8vb" force deleted $ oc get pods -A | grep openshift-authentication openshift-authentication-operator authentication-operator-8bdb6b997-r5vlp 1/1 Running 0 143m openshift-authentication oauth-openshift-56d45f4dc6-5j4k2 1/1 Running 0 35s openshift-authentication oauth-openshift-56d45f4dc6-jzqhk 1/1 Running 0 142m $ oc logs oauth-openshift-56d45f4dc6-5j4k2 -n openshift-authentication | grep 'configmap "extension-apiserver-authentication" not found' W0403 09:38:58.937025 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 W0403 09:38:58.937638 1 configmap_cafile_content.go:102] unable to load initial CA bundle for: "client-ca::kube-system::extension-apiserver-authentication::requestheader-client-ca-file" due to: configmap "extension-apiserver-authentication" not found We can see the above message will be printed at the pod startup.
