Summary
Kube-proxy may unintentionally forward traffic
Details
Kube-proxy on 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.
