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 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-iptables If true cleanup iptables rules and exit.
--cluster-cidr string 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 duration How often configuration from the apiserver is refreshed. Must be greater than 0. (default 15m0s)
--conntrack-max-per-core int32 Maximum number of NAT connections to track per CPU core (0 to leave the limit as-is and ignore conntrack-min). (default 32768)
--conntrack-min int32 Minimum number of conntrack entries to allocate, regardless of conntrack-max-per-core (set conntrack-max-per-core=0 to leave the limit as-is). (default 131072)
--conntrack-tcp-timeout-close-wait duration NAT timeout for TCP connections in the CLOSE_WAIT state (default 1h0m0s)
--conntrack-tcp-timeout-established duration Idle timeout for established TCP connections (0 to leave as-is) (default 24h0m0s)
--feature-gates mapStringBool A set of key=value pairs that describe feature gates for alpha/experimental features. Options are:
AllAlpha=true|false (ALPHA - default=false)
AllowExtTrafficLocalEndpoints=true|false (BETA - default=true)
AppArmor=true|false (BETA - default=true)
DynamicKubeletConfig=true|false (ALPHA - default=false)
DynamicVolumeProvisioning=true|false (ALPHA - default=true)
ExperimentalHostUserNamespaceDefaulting=true|false (ALPHA - default=false)
StreamingProxyRedirects=true|false (ALPHA - default=false)
--healthz-bind-address ip 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) (default 127.0.0.1)
--healthz-port int32 The port to bind the health check server. Use 0 to disable. (default 10249)
--hostname-override string If non-empty, will use this string as identification instead of the actual hostname.
--iptables-masquerade-bit int32 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]. (default 14)
--iptables-min-sync-period duration The minimum interval of how often the iptables rules can be refreshed as endpoints and services change (e.g. '5s', '1m', '2h22m').
--iptables-sync-period duration The maximum interval of how often iptables rules are refreshed (e.g. '5s', '1m', '2h22m'). Must be greater than 0. (default 30s)
--kube-api-burst int32 Burst to use while talking with Kubernetes apiserver (default 10)
--kube-api-content-type string Content type of requests sent to apiserver. (default "application/vnd.kubernetes.protobuf")
--kube-api-qps float32 QPS to use while talking with Kubernetes apiserver (default 5)
--kubeconfig string Path to kubeconfig file with authorization information (the master location is set by the master flag).
--masquerade-all If using the pure iptables proxy, SNAT everything
--master string The address of the Kubernetes API server (overrides any value in kubeconfig)
--oom-score-adj int32 The oom-score-adj value for kube-proxy process. Values must be within the range [-1000, 1000] (default -999)
--proxy-mode ProxyMode 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 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 duration 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 (default 250ms)
