Usage: kublet
The kubelet is the primary "node agent" that runs on each
node. It can register the node with the apiserver using one of: the hostname; a flag to
override the hostname; or specific logic for a cloud provider.
The kubelet works in terms of a PodSpec. A PodSpec is a YAML or JSON object
that describes a pod. The kubelet takes a set of PodSpecs that are provided through
various mechanisms (primarily through the apiserver) and ensures that the containers
described in those PodSpecs are running and healthy. The kubelet doesn't manage
containers which were not created by Kubernetes.
Other than from an PodSpec from the apiserver, there are two ways that a container
manifest can be provided to the Kubelet.
File: Path passed as a flag on the command line. Files under this path will be monitored
periodically for updates. The monitoring period is 20s by default and is configurable
via a flag.
HTTP endpoint: HTTP endpoint passed as a parameter on the command line. This endpoint
is checked every 20 seconds (also configurable with a flag).
Usage:
kubelet [flags]
Flags:
--address ip The IP address for the Kubelet to serve on (set to '0.0.0.0' or '::' for listening in all interfaces and IP families) (default 0.0.0.0) (DEPRECATED: This parameter should be set via the config file specified by the Kubelet's --config flag.

--bootstrap-kubeconfig string Path to a kubeconfig file that will be used to get client certificate for kubelet. If the file specified by --kubeconfig does not exist, the bootstrap kubeconfig is used to request a client certificate from the API server.

Usage: kube-proxy
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 The IP address for the proxy server to serve on (set to '0.0.0.0' for all IPv4 interfaces and '::' for all IPv6 interfaces). 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

--nodeport-addresses strings A string slice of values which specify the addresses to use for NodePorts. Values may be valid IP blocks (e.g. 1.2.3.0/24, 1.2.3.4/32).

--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.

--version version[=true] Print version information and quit
--vmodule moduleSpec comma-separated list of pattern=N settings for file-filtered logging (only works for the default text log format)
