      *Previously, the `ingresscontroller.spec.tuniningOptions.reloadInterval` did not support decimal points as valid for `reloadInterval`. This caused an `ingress-controller` to become invalid and unable to be deleted. With this update, `ingresscontroller.spec.tuningOptions.reloadInterval` supports decimals and users can delete ingress controllers with previously unsupported time units.

      shudi@Shudis-MacBook-Pro openshift-tests-private % 

      3.  show the ingress-controllers

      shudi@Shudis-MacBook-Pro openshift-tests-private % oc -n openshift-ingress-operator get ingresscontroller

      NAME       AGE

      default    113m

      ocp53608   42m

      shudi@Shudis-MacBook-Pro openshift-tests-private %

       

      4. Try to delete the ingress-controller ocp53608, when the message "ingresscontroller.operator.openshift.io "ocp53608" deleted" appears, it is hanged for a long time until the error message appears.

      shudi@Shudis-MacBook-Pro openshift-tests-private % oc -n openshift-ingress-operator delete ingresscontroller ocp53608

      ingresscontroller.operator.openshift.io "ocp53608" deleted

      error: An error occurred while waiting for the object to be deleted: an error on the server ("unable to decode an event from the watch stream: http2: client connection lost") has prevented the request from succeedingUnable to connect to the server: dial tcp 35.194.1.60:6443: i/o timeout

      shudi@Shudis-MacBook-Pro openshift-tests-private %

       

      5. After "ingresscontroller.operator.openshift.io "ocp53608" deleted" message appears, show the ingress-controller, ocp53608 isn't deleted

      shudi@Shudis-MacBook-Pro golang % oc -n openshift-ingress-operator get ingresscontroller

      NAME       AGE

      default    3h

      ocp53608   109m

      shudi@Shudis-MacBook-Pro golang %

       

      6.  After the error message(rror: An error occurred while waiting for the object to be deleted) appears, try to show the ingresscontroller

      shudi@Shudis-MacBook-Pro openshift-tests-private % oc -n openshift-ingress-operator get ingresscontroller

      Actual results:  ingress-controller ocp53608  is still there after executed the oc delete command

      Expected results:

      ingress-controller ocp53608  will be deleted soon after executed the oc delete command
