Kubernetes Reference Documentation

--- title: Reference approvers: - chenopis linkTitle: "Reference" main_menu: true weight: 70 content_type: concept no_list: true ---  This section of the Kubernetes documentation contains references.  ## API Reference * [Glossary](/docs/reference/glossary/) - a comprehensive, standardized list of Kubernetes terminology * [Kubernetes API Reference](/docs/reference/kubernetes-api/) * [One-page API Reference for Kubernetes {{< param "version" >}}](/docs/reference/generated/kubernetes-api/{{< param "version" >}}/) * [Using The Kubernetes API](/docs/reference/using-api/) - overview of the API for Kubernetes. * [API access control](/docs/reference/access-authn-authz/) - details on how Kubernetes controls API access * [Well-Known Labels, Annotations and Taints](/docs/reference/labels-annotations-taints/) ## Officially supported client libraries To call the Kubernetes API from a programming language, you can use [client libraries](/docs/reference/using-api/client-libraries/). Officially supported client libraries: - [Kubernetes Go client library](https://github.com/kubernetes/client-go/) - [Kubernetes Python client library](https://github.com/kubernetes-client/python) - [Kubernetes Java client library](https://github.com/kubernetes-client/java) - [Kubernetes JavaScript client library](https://github.com/kubernetes-client/javascript) - [Kubernetes C# client library](https://github.com/kubernetes-client/csharp) - [Kubernetes Haskell client library](https://github.com/kubernetes-client/haskell) ## CLI * [kubectl](/docs/reference/kubectl/) - Main CLI tool for running commands and managing Kubernetes clusters. * [JSONPath](/docs/reference/kubectl/jsonpath/) - Syntax guide for using [JSONPath expressions](https://goessner.net/articles/JsonPath/) with kubectl. * [kubeadm](/docs/reference/setup-tools/kubeadm/) - CLI tool to easily provision a secure Kubernetes cluster. ## Components * [kubelet](/docs/reference/command-line-tools-reference/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](/docs/reference/command-line-tools-reference/kube-apiserver/) - REST API that validates and configures data for API objects such as pods, services, replication controllers. * [kube-controller-manager](/docs/reference/command-line-tools-reference/kube-controller-manager/) - Daemon that embeds the core control loops shipped with Kubernetes. * [kube-proxy](/docs/reference/command-line-tools-reference/kube-proxy/) - Can do simple TCP/UDP stream forwarding or round-robin TCP/UDP forwarding across a set of back-ends. * [kube-scheduler](/docs/reference/command-line-tools-reference/kube-scheduler/) - Scheduler that manages availability, performance, and capacity. * [Scheduler Policies](/docs/reference/scheduling/policies) * [Scheduler Profiles](/docs/reference/scheduling/config#profiles)

This section provides comprehensive references for Kubernetes, including API documentation, officially supported client libraries, command-line tools (kubectl and kubeadm), and core components like kubelet, kube-apiserver, kube-controller-manager, kube-proxy, and kube-scheduler. It also includes a glossary, information on API access control, and well-known labels, annotations, and taints.
