How to Investigate Kubernetes Nodes That Become NotReady

A node may become NotReady because of network plugin issues, resource pressure, kubelet problems, or host failure.

Checks to make

Review node conditions and events, kubelet and system logs, resource pressure, and control-plane connectivity. Check whether pods were rescheduled and whether storage or local state needs protection before rebooting or replacing the node.

When to get help
