This reflects services as defined in the Kubernetes API on each node and can do simple TCP, UDP, and SCTP stream forwarding or round robin TCP, UDP, and SCTP forwarding across a set of backends. Service cluster IPs and ports are currently found through Docker-links-compatible environment variables specifying ports opened by the service proxy. There is an optional addon that provides cluster DNS for these cluster IPs. The user must create a service with the apiserver API to configure the proxy. +`` + +In order to view the list of options for running kube-proxy, please refer to the "Options" section in the same documentation: +https://kubernetes.io/docs/reference/command-line-tools-reference/kube-proxy/ + + +## Additional kube-proxy resources +The official Kubernetes Reference documentation provides a diagram and writeup on how the kube-proxy fits in the kubernetes ecosystem: + +https://kubernetes.io/docs/concepts/overview/components/ + + +## Downloading and building kube-proxy from the Iron Bank +1.
