Upstream information
Description
Kube-proxyon Windows can unintentionally forward traffic to local processes
listening on the same port ("spec.ports[*].port") as a LoadBalancer
Service when the LoadBalancer controller
does not set the "status.loadBalancer.ingress[].ip" field. Clusters
where the LoadBalancer controller sets the
"status.loadBalancer.ingress[].ip" field are unaffected.
