Kubernetes 1.27: Query Node Logs Using The Kubelet API

Kubernetes 1.27 introduces "Node log query," which enables cluster administrators to view logs of services running on the node using kubectl.

This feature helps to debug malfunctioning services running on the node and is especially useful for Windows nodes. The feature uses heuristics to retrieve logs and requires proper RBAC authorization.

To use it, ensure that the NodeLogQuery feature is enabled and the kubelet configuration options enableSystemLogHandler and enableSystemLogQuery are set to true.
