In computing, a proxy is a server that acts as an intermediary for a remote service.

A client interacts with the proxy; the proxy copies the client's data to the actual server; the actual server replies to the proxy; the proxy sends the actual server's reply to the client.

kube-proxy is a network proxy that runs on each node in your cluster, implementing part of the Kubernetes {{< glossary_tooltip term_id="service">}} concept.

You can run kube-proxy as a plain userland proxy service. If your operating system supports it, you can instead run kube-proxy in a hybrid mode that achieves the same overall effect using less system resources.
