NAME¶
kube-proxy - network proxy services
SYNOPSIS¶
kube-proxy [OPTIONS]
DESCRIPTION¶
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.
--cluster-cidr=""
The CIDR range of pods in the cluster. It is used to bridge traffic coming
from outside of the cluster. If not provided, no off-cluster bridging will
be performed.
--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=24h0m0s
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-masquerade-bit=14
If using the pure iptables proxy, the bit of the fwmark space to mark packets
requiring SNAT with. Must be within the range [0, 31].
--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
