Description Hongan Li 2021-04-14 09:47:56 UTC

Description of problem:
ingressclass controller doesn't recreate the openshift-default ingressclass after deleting it

Version-Release number of selected component (if applicable):
4.8.0-0.nightly-2021-04-13-171608

How reproducible:
100%

Steps to Reproduce:
1. fresh install 4.8 cluster
2. check the ingressclass
$ oc get ingressclass
NAME                CONTROLLER                      PARAMETERS                                        AGE
openshift-default   openshift.io/ingress-to-route   IngressController.operator.openshift.io/default   8h

3. delete the ingressclass
$ oc delete ingressclass openshift-default

Actual results:
ingressclass controller doesn't recreate the openshift-default ingressclass until restarting ingress operator pod.

Expected results:
ingressclass controller should recreate the openshift-default ingressclass after deleting it.

Additional info:
workaround: restarting ingress operator pod
