Start with the reported node-exporter pod events and the single-node Docker Desktop Kubernetes setup; inspect the node-exporter deployment and mount configuration. No repository file, test, or requested change is identified, so first establish whether this belongs as website documentation or an upstream configuration fix, then verify the pod no longer enters CrashLoopBackOff.
