I’d check node conditions first. Disk pressure could be a reason.

I vaguely recall needing to check the network configuration or resource limits. I hope I can figure out how to make the changes permanent!

This seems similar to a practice question where we had to troubleshoot a pod issue. I wonder if the same steps apply here?

I think we might need to look at the kubelet logs to find out why the node is in that state. I hope I can remember the command for that.

I remember we practiced checking the node status with `kubectl get nodes`, but I'm not sure what to do if it's NotReady.
