Applications that consume the Kubernetes REST API should implement API calls, including request and response types. Considering the rich set of Kubernetes resources that are provided to us, developing and maintaining API implementation becomes complex. Fortunately, Kubernetes has a rich set of official client libraries that are implemented in various programming languages. Client libraries do not only handle requests and responses, but also handle authentication to the API server. Besides, most of the client libraries can discover and connect to the Kubernetes API server if it is running inside the cluster.
In this section, official Go and Python client libraries will be presented. The client repositories, documentation, how to install, and how to create simple applications that are running inside and outside the clusters will be covered.
