kube proxy

kube-proxy

All of the worker nodes run a daemon called kube-proxy, which watches the API server on the master node for the addition and removal of Services and endpoints. For each new Service, on each node, kube-proxy configures the iptables rules to capture the traffic for its ClusterIP and forwards it to one of the endpoints. When the service is removed, kube-proxy removes the iptables rules on all nodes as well.
