Explanation
The kube-scheduler is a control plane process that assigns pods to nodes based on scheduling principles, such as resource requirements, affinity, anti-affinity, and more. The kube-scheduler watches for newly created pods that have no node assigned and selects an optimal node for each pod to run on. The kube-scheduler does not start pods, scale nodes, or schedule Cron Jobs. These are the responsibilities of other components, such as the kubelet, the cluster autoscaler, and the kube-controller-manager. References: Kubernetes Scheduler, kube-scheduler
