Description Lukasz Szaszkiewicz 2020-05-05 07:29:39 UTC
move https://github.com/kubernetes/kubernetes/pull/90297 into origin so that help is not printed when kube-apiserver fails with a non usage based error

Comment 3 Ke Wang 2020-05-07 07:45:51 UTC
Verified with OCP build 4.5.0-0.nightly-2020-05-06-003431,

- On 4.4 OCP without fix ENV, get the related errors
...
2020-05-06T15:10:17.009079506+00:00 stderr F Usage:
2020-05-06T15:10:17.009079506+00:00 stderr F   kube-apiserver [flags]

- In one terminal, enter into master 
$ master=$(oc get nodes | grep master | head -1 | cut -d " " -f1)
$ oc debug node/$master
sh-4.2# chroot /host
Try incorrect parameter to endpoint,
sh-4.4#  curl -k --silent --show-error https://localhost:6443/readyz1

$ cd /var/log/pods

$ grep -nr -i 'usage' openshift-*

No results found.

So the bug was fixed, move the bug verified.
