output: This section of the Kubernetes documentation contains references.
  API Reference
  Glossary
  - a comprehensive, standardized list of Kubernetes terminology
  Kubernetes API Reference
  One-page API Reference for Kubernetes v1.33
  Using The Kubernetes API
  - overview of the API for Kubernetes.
  API access control
  - details on how Kubernetes controls API access
  Well-Known Labels, Annotations and Taints
  Officially supported client libraries
  To call the Kubernetes API from a programming language, you can use
  client libraries
  . Officially supported
  client libraries:
  Kubernetes Go client library
  Kubernetes Python client library
  Kubernetes Java client library
  Kubernetes JavaScript client library
  Kubernetes C# client library
  Kubernetes Haskell client library
  kubectl
  - 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.
  Components
  kubelet
  - 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 Policies
  Scheduler Profiles
  List of
  ports and protocols
  that
  should be open on control plane and worker nodes
  Config APIs
  This section hosts the documentation for "unpublished" APIs which are used to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.
