segfault from static-egressip-controller #45

Open howels opened 4 years ago

Managed to load everything but seeing segfaults from static-egressip-controller. No hints as to what is happening. Any ideas?

Running on k8s 1.14.3 (edited the CRDs to use the older beta API version) with Flannel.

$ kubectl get pods -o wide -n kube-system -l name=static-egressip-gateway-manager

Hi, I had the same issue and found the solution here https://github.com/nirmata/kube-static-egress-ip/issues/33 probably you have missed in the logs where it says that it doesn't find the service endpoints. You have to redeploy the resources in the same namespace where you service is.
