  client libraries:Kubernetes Go client libraryKubernetes Python client libraryKubernetes Java client libraryKubernetes JavaScript client libraryKubernetes C# client libraryKubernetes Haskell client libraryCLIkubectl - Main CLI tool for running commands and managing Kubernetes clusters.JSONPath - Syntax guide for using JSONPath expressions with kubectl.kubeadm - CLI tool to easily provision a secure Kubernetes cluster.Componentskubelet - The
  primary agent that runs on each node. The kubelet takes a set of PodSpecs
  and ensures that the described containers are running and healthy.kube-apiserver -
  REST API that validates and configures data for API objects such as pods,
  services, replication controllers.kube-controller-manager -
  Daemon that embeds the core control loops shipped with Kubernetes.kube-proxy - Can
  do simple TCP/UDP stream forwarding or round-robin TCP/UDP forwarding across
  a set of back-ends.kube-scheduler -
  Scheduler that manages availability, performance, and capacity.Scheduler PoliciesScheduler ProfilesList of ports and protocols that
  should be open on control plane and worker nodesConfig APIsThis section hosts the documentation for "unpublished" APIs which are used to
  configure kubernetes components or tools. Most of these APIs are not exposed
  by the API server in a RESTful way though they are essential for a user or an
  operator to use or manage a cluster.kubeconfig (v1)kuberc (v1alpha1)kube-apiserver admission (v1)kube-apiserver configuration (v1alpha1) andkube-apiserver configuration (v1beta1) and
