## 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,UDP stream forwarding or round robin TCP,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.
|
|
|
|
```
|
|
kube-proxy
|
|
```
|
|
|
|
### Options
|
|
|
|
```
|
|
--bind-address=0.0.0.0: The IP address for the proxy server to serve on (set to 0.0.0.0 for all interfaces)
|
|
--cleanup-iptables[=false]: If true cleanup iptables rules and exit.
|
|
--config-sync-period=15m0s: How often configuration from the apiserver is refreshed. Must be greater than 0.
|
|
--conntrack-max=262144: Maximum number of NAT connections to track (0 to leave as-is)
|
|
--conntrack-tcp-timeout-established=86400: Idle timeout for established TCP connections (0 to leave as-is)
|
|
--google-json-key="": The Google Cloud Platform Service Account JSON Key to use for authentication.
|
|
--healthz-bind-address=127.0.0.1: The IP address for the health check server to serve on, defaulting to 127.0.0.1 (set to 0.0.0.0 for all interfaces)
|
|
--healthz-port=10249: The port to bind the health check server. Use 0 to disable.
|
|
--hostname-override="": If non-empty, will use this string as identification instead of the actual hostname.
|
|
--iptables-sync-period=30s: How often iptables rules are refreshed (e.g. '5s', '1m', '2h22m'). Must be greater than 0.
|
|
--kube-api-burst=10: Burst to use while talking with kubernetes apiserver
|
|
--kube-api-qps=5: QPS to use while talking with kubernetes apiserver
|
|
--kubeconfig="": Path to kubeconfig file with authorization information (the master location is set by the master flag).
|
|
--log-flush-frequency=5s: Maximum number of seconds between log flushes
|
|
--masquerade-all[=false]: If using the pure iptables proxy, SNAT everything
|
|
--master="": The address of the Kubernetes API server (overrides any value in kubeconfig)
|
|
--oom-score-adj=-999: The oom-score-adj value for kube-proxy process. Values must be within the range [-1000, 1000]
|
|
--proxy-mode="": Which proxy mode to use: 'userspace' (older) or 'iptables' (faster). If blank, look at the Node object on the Kubernetes API and respect the 'net.experimental.kubernetes.io/proxy-mode' annotation if provided. Otherwise use the best-available proxy (currently iptables). If the iptables proxy is selected, regardless of how, but the system's kernel or iptables versions are insufficient, this always falls back to the userspace proxy.
|
|
--proxy-port-range=: Range of host ports (beginPort-endPort, inclusive) that may be consumed in order to proxy service traffic. If unspecified (0-0) then ports will be randomly chosen.
|
|
--udp-timeout=250ms: How long an idle UDP connection will be kept open (e.g. '250ms', '2s'). Must be greater than 0. Only applicable for proxy-mode=userspace
|
|
