Tip: Ngnix ingress controller can't startup


     We try to restart a pod of nginx ingress controller. After the restart, the pods can't startup 

Error like

status.go:274] updating Ingress ingress-nginx-internal/prometheus-ingress status from [] to [{ }]

I1226 02:11:14.106423       6 event.go:255] Event(v1.ObjectReference{Kind:"Ingress", Namespace:"ingress-nginx-internal", Name:"prometheus-ingress", UID:"e26f55f2-d87d-4efe-a4dd-5ae02768814a", APIVersion:"", ResourceVersion:"46816813", FieldPath:""}): type: 'Normal' reason: 'UPDATE' Ingress ingress-nginx-internal/prometheus-ingress

I1226 02:11:49.153889       6 main.go:153] Received SIGTERM, shutting down

I1226 02:11:49.153931       6 nginx.go:390] Shutting down controller queues


   Somehow the existing ingress rule "prometheus-ingress" is the causeRemove the rule then the pod can startup well. We can add the rule back after that.
