The Kubernetes API server is the access gateway to a Kubernetes cluster. This topic introduces the kube-apiserver component and its usage notes, and lists the latest changes to the component.
The Kubernetes API server validates and configures data for the API objects, which include pods, Services, and ReplicationControllers. The Kubernetes API server serves REST operations and provides a frontend to the shared state of the cluster. All other components interact through this frontend.
The kube-apiserver component is automatically installed. You can use it without extra configurations.
The kube-apiserver component is upgraded along with the Kubernetes version. For more information, see Overview of Kubernetes versions supported by ACK.
