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, 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.

Usage:
  kube-proxy [flags]

Flags:
      --bind-address ip                              Overrides kube-proxy's idea of what its node's primary IP is. Note that the name is a historical artifact, and kube-proxy does not actually bind any sockets to this IP. This parameter is ignored if a config file is specified by --config. (default 0.0.0.0)
      --bind-address-hard-fail                       If true kube-proxy will treat failure to bind to a port as fatal and exit
      --boot-id-file string                          Comma-separated list of files to check for boot-id. Use the first one that exists. (default "/proc/sys/kernel/random/boot_id")
      --cleanup                                      If true cleanup iptables and ipvs rules and exit.
      --cluster-cidr string                          The CIDR range of the pods in the cluster. (For dual-stack clusters, this can be a comma-separated dual-stack pair of CIDR ranges.). When --detect-local-mode is set to ClusterCIDR, kube-proxy will consider traffic to be local if its source IP is in this range. (Otherwise it is not used.) This parameter is ignored if a config file is specified by --config.
      --config string                                The path to the configuration file.
      --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-be-liberal                     Enable liberal mode for tracking TCP packets by setting nf_conntrack_tcp_be_liberal to 1
      --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)
      --conntrack-udp-timeout duration               Idle timeout for UNREPLIED UDP connections (0 to leave as-is)
      --conntrack-udp-timeout-stream duration        Idle timeout for ASSURED UDP connections (0 to leave as-is)
      --detect-local-mode LocalMode                  Mode to use to detect local traffic. This parameter is ignored if a config file is specified by --config.
      --feature-gates mapStringBool                  A set of key=value pairs that describe feature gates for alpha/experimental features. Options are:

      --log-json-split-stream                        [Alpha] In JSON format, write error messages to stderr and info messages to stdout. The default is to write a single stream to stdout. Enable the LoggingAlphaOptions feature gate to use this.
      --log-text-info-buffer-size quantity           [Alpha] In text format with split output streams, the info messages can be buffered for a while to increase performance. The default value of zero bytes disables buffering. The size can be specified as number of bytes (512), multiples of 1000 (1K), multiples of 1024 (2Ki), or powers of those (3M, 4G, 5Mi, 6Gi).

      --masquerade-all                               SNAT all traffic sent via Service cluster IPs. This may be required with some CNI plugins. Only supported on Linux.

(Set to "0.0.0.0:10249" / "[::]:10249" to bind on all interfaces.) Set empty to disable. This parameter is ignored if a config file is specified by --config. (default 127.0.0.1:10249)
      --nodeport-addresses strings                   A list of CIDR ranges that contain valid node IPs, or alternatively, the single string 'primary'. If set to a list of CIDRs, connections to NodePort services will only be accepted on node IPs in one of the indicated ranges. If set to 'primary', NodePort services will only be accepted on the node's primary IP(s) according to the Node object. If unset, NodePort connections will be accepted on all local IPs. This parameter is ignored if a config file is specified by --config.
      --oom-score-adj int32                          The oom-score-adj value for kube-proxy process. Values must be within the range [-1000, 1000]. This parameter is ignored if a config file is specified by --config. (default -999)
      --pod-bridge-interface string                  A bridge interface name. When --detect-local-mode is set to BridgeInterface, kube-proxy will consider traffic to be local if it originates from this bridge.
      --pod-interface-name-prefix string             An interface name prefix. When --detect-local-mode is set to InterfaceNamePrefix, kube-proxy will consider traffic to be local if it originates from any interface whose name begins with this prefix.

      --show-hidden-metrics-for-version string       The previous version for which you want to show hidden metrics. Only the previous minor version is meaningful, other values will not be allowed. The format is <major>.<minor>, e.g.: '1.16'. The purpose of this format is make sure you have the opportunity to notice if the next release hides additional metrics, rather than being surprised when they are permanently removed in the release after that. This parameter is ignored if a config file is specified by --config.
