The controller manager (kube-controller-manager) ensures that the desired configuration of Kubernetes resources is reflected in the cluster. etcd provides a data store for the cluster configuration.
The kube-apiserver must be started with the --authorization-mode=ABAC and --authorization-policy-file=filename parameters.
For high availability of the control plane, in case of a failure of one of the master nodes.
