kube-proxy

Synopsis

The Kubernetes network proxy runs on each node. This reflects services as defined in the Kubernetes API on each node and can do simple TCP and UDP stream forwarding or round robin TCP and UDP 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.

      --bind-address ip                              The IP address for the proxy server to serve on (set to 0.0.0.0 for all interfaces) (default 0.0.0.0)
      --cleanup                                      If true cleanup iptables and ipvs rules and exit.
