This includes proxying requests to a user api-server and calling out to webhook admission plugins. It is expected that this cert includes a signature from the CA in the --requestheader-client-ca-file flag. That CA is published in the 'extension-apiserver-authentication' configmap in the kube-system namespace. Components receiving calls from kube-aggregator should use that CA to perform their half of the mutual TLS verification.

--storage-versions string The per-group version to store resources in. Specified in the format "group1/version1,group2/version2,...". In the case where objects are moved from one group to the other, you may specify the format "group1=group2/v1beta1,group3/v1beta1,...". You only need to pass the groups you wish to change from the defaults. It defaults to a list of preferred versions of all registered groups, which is derived from the KUBE_API_VERSIONS environment variable. (default "admission.k8s.io/v1alpha1,admissionregistration.k8s.io/v1alpha1,apps/v1beta1,authentication.k8s.io/v1,authorization.k8s.io/v1,autoscaling/v1,batch/v1,certificates.k8s.io/v1beta1,componentconfig/v1alpha1,extensions/v1beta1,federation/v1beta1,imagepolicy.k8s.io/v1alpha1,networking.k8s.io/v1,policy/v1beta1,rbac.authorization.k8s.io/v1beta1,scheduling.k8s.io/v1alpha1,settings.k8s.io/v1alpha1,storage.k8s.io/v1,v1")

--tls-cert-file string File containing the default x509 Certificate for HTTPS. (CA cert, if any, concatenated after server cert). If HTTPS serving is enabled, and --tls-cert-file and --tls-private-key-file are not provided, a self-signed certificate and key are generated for the public address and saved to /var/run/kubernetes.
--tls-private-key-file string File containing the default x509 private key matching --tls-cert-file.
--tls-sni-cert-key namedCertKey A pair of x509 certificate and private key file paths, optionally suffixed with a list of domain patterns which are fully qualified domain names, possibly with prefixed wildcard segments. If no domain patterns are provided, the names of the certificate are extracted. Non-wildcard matches trump over wildcard matches, explicit domain patterns trump over extracted names. For multiple key/certificate pairs, use the --tls-sni-cert-key multiple times. Examples: "example.crt,example.key" or "foo.crt,foo.key:*.foo.com,foo.com". (default [])
--token-auth-file string If set, the file that will be used to secure the secure port of the API server via token authentication.

## kube-controller-manager
### Synopsis
The Kubernetes controller manager is a daemon that embeds
the core control loops shipped with Kubernetes. In applications of robotics and
automation, a control loop is a non-terminating loop that regulates the state of
the system. In Kubernetes, a controller is a control loop that watches the shared
state of the cluster through the apiserver and makes changes attempting to move the
current state towards the desired state. Examples of controllers that ship with
Kubernetes today are the replication controller, endpoints controller, namespace
controller, and serviceaccounts controller.

## 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-scheduler
### Synopsis
The Kubernetes scheduler is a policy-rich, topology-aware,
workload-specific function that significantly impacts availability, performance,
and capacity. The scheduler needs to take into account individual and collective
resource requirements, quality of service requirements, hardware/software/policy
constraints, affinity and anti-affinity specifications, data locality, inter-workload
interference, deadlines, and so on. Workload-specific requirements will be exposed
through the API as necessary.

## kubelet
### Synopsis
The kubelet is the primary "node agent" that runs on each
node. 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 a PodSpec from the apiserver, there are three 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).
HTTP server: The kubelet can also listen for HTTP and respond to a simple API
(underspec'd currently) to submit a new manifest.
```
kubelet
```
### Options
```
--address ip The IP address for the Kubelet to serve on (set to 0.0.0.0 for all interfaces) (default 0.0.0.0)
--allow-privileged If true, allow containers to request privileged mode.
--anonymous-auth Enables anonymous requests to the Kubelet server. Requests that are not rejected by another authentication method are treated as anonymous requests. Anonymous requests have a username of system:anonymous, and a group name of system:unauthenticated. (default true)
--authentication-token-webhook Use the TokenReview API to determine authentication for bearer tokens.
--authentication-token-webhook-cache-ttl duration The duration to cache responses from the webhook token authenticator. (default 2m0s)
--authorization-mode string Authorization mode for Kubelet server. Valid options are AlwaysAllow or Webhook. Webhook mode uses the SubjectAccessReview API to determine authorization. (default "AlwaysAllow")

--azure-container-registry-config string Path to the file container Azure container registry configuration information.
--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. On success, a kubeconfig file referencing the generated client certificate and key is written to the path specified by --kubeconfig. The client certificate and key file will be stored in the directory pointed by --cert-dir.
--cadvisor-port int32 The port of the localhost cAdvisor endpoint (set to 0 to disable) (default 4194)
--cert-dir string The directory where the TLS certs are located. If --tls-cert-file and --tls-private-key-file are provided, this flag will be ignored. (default "/var/run/kubernetes")
--cgroup-driver string Driver that the kubelet uses to manipulate cgroups on the host. Possible values: 'cgroupfs', 'systemd' (default "cgroupfs")
--cgroup-root string Optional root cgroup to use for pods. This is handled by the container runtime on a best effort basis. Default: '', which means use the container runtime default.
--cgroups-per-qos Enable creation of QoS cgroup hierarchy, if true top level QoS and pod cgroups are created. (default true)
--chaos-chance float If > 0.0, introduce random client errors and latency. Intended for testing.
--client-ca-file string If set, any request presenting a client certificate signed by one of the authorities in the client-ca-file is authenticated with an identity corresponding to the CommonName of the client certificate.
--cloud-config string The path to the cloud provider configuration file. Empty string for no configuration file.
--cloud-provider string The provider for cloud services. By default, kubelet will attempt to auto-detect the cloud provider (deprecated). Specify empty string for running with no cloud provider, this will be the default in upcoming releases. (default "auto-detect")
--cluster-dns stringSlice Comma-separated list of DNS server IP address. This value is used for containers DNS server in case of Pods with "dnsPolicy=ClusterFirst". Note: all DNS servers appearing in the list MUST serve the same set of records otherwise name resolution within the cluster may not work correctly. There is no guarantee as to which DNS server may be contacted for name resolution.
--cluster-domain string Domain for this cluster. If set, kubelet will configure all containers to search this domain in addition to the host's search domains
--cni-bin-dir string <Warning: Alpha feature> The full path of the directory in which to search for CNI plugin binaries. Default: /opt/cni/bin
--cni-conf-dir string <Warning: Alpha feature> The full path of the directory in which to search for CNI config files. Default: /etc/cni/net.d
--container-runtime string The container runtime to use. Possible values: 'docker', 'rkt'. (default "docker")
--container-runtime-endpoint string [Experimental] The endpoint of remote runtime service. Currently unix socket is supported on Linux, and tcp is supported on windows. Examples:'unix:///var/run/dockershim.sock', 'tcp://localhost:3735' (default "unix:///var/run/dockershim.sock")
--containerized Experimental support for running kubelet in a container. Intended for testing.
--contention-profiling Enable lock contention profiling, if profiling is enabled
--cpu-cfs-quota Enable CPU CFS quota enforcement for containers that specify CPU limits (default true)
--cpu-manager-policy string <Warning: Alpha feature> CPU Manager policy to use. Possible values: 'none', 'static'. Default: 'none' (default "none")
--cpu-manager-reconcile-period NodeStatusUpdateFrequency <Warning: Alpha feature> CPU Manager reconciliation period. Examples: '10s', or '1m'. If not supplied, defaults to NodeStatusUpdateFrequency (default 10s)
--docker-disable-shared-pid The Container Runtime Interface (CRI) defaults to using a shared PID namespace for containers in a pod when running with Docker 1.13.1 or higher. Setting this flag reverts to the previous behavior of isolated PID namespaces. This ability will be removed in a future Kubernetes release. (default true)
--docker-endpoint string Use this for the docker endpoint to communicate with (default "unix:///var/run/docker.sock")
--dynamic-config-dir string The Kubelet will use this directory for checkpointing downloaded configurations and tracking configuration health. The Kubelet will create this directory if it does not already exist. The path may be absolute or relative; relative paths start at the Kubelet's current working directory. Providing this flag enables dynamic Kubelet configuration. Presently, you must also enable the DynamicKubeletConfig feature gate to pass this flag.
--enable-controller-attach-detach Enables the Attach/Detach controller to manage attachment/detachment of volumes scheduled to this node, and disables kubelet from executing any attach/detach operations (default true)
--enable-custom-metrics Support for gathering custom metrics.
