The Kubernetes master is the main component of the Kubernetes cluster. It serves several functionalities, such as the following:

• Authorization and authentication
• RESTful API entry point
• Container deployment scheduler to Kubernetes nodes
• Scaling and replicating controllers
• Reading the configuration to set up a cluster

The following diagram shows how master daemons work together to fulfill the aforementioned functionalities:

There are several daemon processes that form the Kubernetes master's functionality, such as kube-apiserver, kube-scheduler and kube-controller-manager. Hypercube, the wrapper binary, can launch all these daemons.

In addition, the Kubernetes command-line interface, kubect can control the Kubernetes master functionality.
