Klipper in wrong namespace and not able to kill the pods #38

Open ralphflat opened 2 years ago

ralphflat commented 2 years ago

We are using the KlipperLB load balancer and are finding that the svclb services are getting created in the kube-system namespaces. In addition, we can not delete the pods in that namespace - the initial pod is deleted, but then it gets recreated, so it won't die. Initial pods in kube-system namespace:

k get pods -n kube-system
