  * [1.12](/docs/reference/generated/kubernetes-api/v1.12/)
  * [1.11](/docs/reference/generated/kubernetes-api/v1.11/)

## API 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)

## CLI Reference

* [kubectl](/docs/user-guide/kubectl-overview) - Main CLI tool for running commands and managing Kubernetes clusters.
    * [JSONPath](/docs/user-guide/jsonpath/) - Syntax guide for using [JSONPath expressions](http://goessner.net/articles/JsonPath/) with kubectl.
* [kubeadm](/docs/admin/kubeadm/) - CLI tool to easily provision a secure Kubernetes cluster.
* [kubefed](/docs/admin/kubefed/) - CLI tool to help you administrate your federated clusters.

## Config Reference

* [kubelet](/docs/admin/kubelet/) - The primary *node 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/admin/kube-apiserver/) - REST API that validates and configures data for API objects such as  pods, services, replication controllers.
* [kube-controller-manager](/docs/admin/kube-controller-manager/) - Daemon that embeds the core control loops shipped with Kubernetes.
* [kube-proxy](/docs/admin/kube-proxy/) - Can do simple TCP/UDP stream forwarding or round-robin TCP/UDP forwarding across a set of back-ends.
* [kube-scheduler](/docs/admin/kube-scheduler/) - Scheduler that manages availability, performance, and capacity.
* [federation-apiserver](/docs/admin/federation-apiserver/) - API server for federated clusters.
* [federation-controller-manager](/docs/admin/federation-controller-manager/) - Daemon that embeds the core control loops shipped with Kubernetes federation.
