Question

A newly created Pod appears in the API server with status 'Pending' and no assigned node. You confirm there are healthy nodes with sufficient free CPU and memory. Which control plane component is responsible for selecting a suitable node and recording that decision so the Pod can start running?

Accepted Answer

The kube-scheduler, which selects a feasible node and writes the binding back to the API server

Answer

The kubelet on each node, which pulls Pending Pods and claims them directly

Answer

The kube-controller-manager, which assigns Pods to nodes during reconciliation

Answer

The kube-proxy, which routes the Pod to the node with the least network traffic
