L7 debug

What's the restart count on the pod?
what's the output of

$ kubectl logs --namespace=kube-system exec l7-lb-controller-v0.5.2-apv4a -c l7-lb-controller

If it's restarting, can you please try:

$ kubectl --namespace=kube-system exec l7-lb-controller-v0.5.2-apv4a -c l7-lb-controller -- curl --silent localhost:8080/healthz
It should return a 200 and the string "ok".
