Answer
kube-proxy manages iptables/IPVS rules to route Service traffic to Pod endpoints.
Quick Answer
kube-proxy runs on every node and programs network rules (iptables or IPVS) that implement Service virtual IPs. When a Pod connects to a Service ClusterIP, kube-proxy's rules intercept the packet and DNAT it to a random healthy Pod backing that Service. It's how Kubernetes load-balances traffic to Services without a dedicated load balancer per Service.
