We should revert the change in https://github.com/openshift/console-operator/pull/328. The router-ca won't work for the case we are trying to handle. It's only present when using system-generated certificates, which don't cause a problem. See https://bugzilla.redhat.com/show_bug.cgi?id=1772775#c1 Note that if we revert it, we will have to add a commit to update starter.go, the RemoveStaleConditionsController() will need RouterCAValidationDegraded & RouterCAValidationProgressing added, else we could have clusters running with wedged operators. Use the same steps as above, now console operator has no panic Verified on 4.4.0-0.nightly-2019-12-15-184910 Since the problem described in this bug report should be resolved in a recent advisory, it has been closed with a resolution of ERRATA.

Description of problem: when RouterCAValidationDegraded failure detected with error `FailedGet router-ca configmap not found` console opeartor panic Version-Release number of selected component (if applicable): 4.3.0-0.nightly-2019-11-13-233341 How reproducible: Always Steps to Reproduce: 1. Generate a CA and certificate (for testing, if you do not already have a CA and certificate): BASE_DOMAIN="$(oc get dns.config/cluster -o 'jsonpath={.spec.baseDomain}')" INGRESS_DOMAIN="$(oc get ingress.config/cluster -o 'jsonpath={.spec.domain}')" openssl genrsa -out example-ca.key 2048 openssl req -x509 -new -key example-ca.key -out example-ca.crt -days 1 -subj "/C=US/ST=NC/L=Chocowinity/O=OS3/OU=Eng/CN=$BASE_DOMAIN" openssl genrsa -out example.key 2048 openssl req -new -key example.key -out example.csr -subj "/C=US/ST=NC/L=Chocowinity/O=OS3/OU=Eng/CN=*.$INGRESS_DOMAIN" openssl x509 -req -in example.csr -CA example-ca.crt -CAkey example-ca.key -CAcreateserial -out example.crt -days 1 2. Patch ingress router to use custom certificate $ oc -n openshift-ingress create secret tls custom-default-cert --cert=example.crt --key=example.key secret/custom-default-cert created $ oc -n openshift-ingress-operator patch ingresscontrollers/default --type=merge --patch='{"spec":{"defaultCertificate":{"name":"custom-default-cert"}}}' ingresscontroller.operator.openshift.io/default patched 3. After ingress router are patched with custom cert, tries to visit console, it reports x509 error then check console operator log 4. Check console operator log $ oc logs -f console-operator-55d4b4455f-hnbvn -n openshift-console-operator Actual results: 4. console operator panic E1115 03:34:52.872929 1 status.go:73]
