+++ This bug was initially created as a clone of Bug #1820255 +++

kube-apiserver can be deployed without cert-syncer having a valid token. This ca be caused by a race when making revisions from token Secret as in https://bugzilla.redhat.com/show_bug.cgi?id=1819256

Comment 3 Ke Wang 2020-04-20 08:00:42 UTC
Verified with OCP build 4.4.0-0.nightly-2020-04-18-095545,
Verification steps:
1. In first terminal, Run this command in a loop to make sure that data.token is deleted from openshift-kube-controller-manager/localhost-recovery-client-token
# for i in {1..100} ; do oc patch secret -n openshift-kube-controller-manager localhost-recovery-client-token --type='json' -p='[{"op": "replace", "path": "/data/token", "value": ""}]'; done

2. In another terminal,  Force operator to retry rolling out by:
$ oc patch kubeapiserver/cluster --type=json -p '[ {"op": "replace", "path": "/spec/forceRedeploymentReason", "value": "forced test 1" } ]' 

$ oc get pods -n openshift-kube-apiserver
kube-apiserver-osp41-7g9pl-master-1      0/4     Init:0/1    0          2s
kube-apiserver can be deployed even though data.token is deleted from openshift-kube-controller-manager/localhost-recovery-client-token.
