Question

An open-data kubelet is still configured with an old API server VIP after a control-plane endpoint change. What is the likely result?

Accepted Answer

The worker cannot reach the control-plane endpoint, so the node becomes or remains NotReady. — Kubelet has to phone home to the API. Point it at yesterday’s VIP and the call drops—NotReady follows.

Answer

Pods schedule normally because kubelets never contact the API server.

Answer

The node auto-rewrites kubeconfig from DNS PTR records within seconds always.

Answer

Only Ingress resources fail; node Ready status is unaffected by kubelet API connectivity.
