Controller manager, as the Management control center within the cluster, is responsible for the resource management in the cluster, including node, Pod, namespace, and rated resources. For example, when an unexpected node outage occurs, Controller Manager will promptly discover and perform an automated fix.First, deploy k8s Controller ManagerMake sure Controller-manager-key.pem and Controller-manager.pem exist, and I've created the relevant private key here in the previous article.

The role of Kubernetes Scheduler is to bind controller manager to a new pod according to a specific scheduling algorithm and scheduling policy to a suitable node in the cluster, and to write the binding information to the ETCD.I. Deployment OF SchedulerThe following generates the Kube-scheduler Kubeconfig file, as follows:cd/etc/kubernetesexport kube_apiserver="https://192.168.15.200:6443"Configure clusterK
