In what situation or for which entity in Kubernetes is the use of the scheduler component (Kube-scheduler) not required?

The Kubernetes scheduler component (kube-scheduler) is responsible for assigning pods to specific cluster nodes. However, there are entities for which a scheduler is not needed:

• Pods with a designated nodeName: if the nodeName field is explicitly specified when creating a pod, the scheduler does not participate — the pod is immediately assigned to the specified node.
• Static Pods: they are created directly on nodes via kubelet and do not go through the scheduler.

Thus, if a pod already has a node assignment or is created statically, kube-scheduler is not required.
