Description Maciej Szulik 2020-05-26 14:02:37 UTC
Since k8s 1.19 is dropping policy config in favor of component config we need to know how many users we have using those configs to better know the impact of this change in 4.6.

Verified bug with the payload below and i see things work as expected. Below are the tests that were run to verify this bug.

[ramakasturinarra@dhcp35-60 ~]$ oc get clusterversion
NAME      VERSION                             AVAILABLE   PROGRESSING   SINCE   STATUS
version   4.5.0-0.nightly-2020-05-27-234738   True        False         9h      Cluster version is 4.5.0-0.nightly-2020-05-27-234738

Install 4.5 cluster with the above payload
config map set in scheduler cluster object.
run command oc get route -A and browse through the prometheus URL
And select the parameter cluster_legacy_scheduler_policy and verify that it is shown as below

cluster_legacy_scheduler_policy{endpoint="https",instance="",job="metrics",namespace="openshift-kube-scheduler-operator",pod="openshift-kube-scheduler-operator-7db8fd5d94-x8zdn",service="metrics"}	0

Now create a configmap and use it with the scheduler cluster object.
Now go to prometheus UI and select the parameter cluster_legacy_scheduler_policy and click on execute.
Verify for the below parameters
cluster_legacy_scheduler_policy{endpoint="https",instance="",job="metrics",namespace="openshift-kube-scheduler-operator",pod="openshift-kube-scheduler-operator-7db8fd5d94-x8zdn",service="metrics"}	1

Based on the above results moving the bug to verified state.
