Architecture

Kubernetes runs in a cluster. A Kubernetes cluster consists of the following components:

  • Nodes run containers with the servers needed by out applications.
  • Controllersconstantly check the cluster nodes current state, and compares it with the desired state.
  • A Control Plane is a set of different components that store the cluster desired state and take decisions about the nodes. The Control Plane provides an API that is used by the controllers.
