Report #1038

[bug\_fix] NodeNotReady caused by DiskPressure, MemoryPressure, or PIDPressure

Run kubectl describe node and inspect Conditions. For DiskPressure, free node disk by pruning unused images with crictl rmi or docker system prune, rotating logs, or expanding the volume. For MemoryPressure, evict or reschedule heavy pods and add memory. For PIDPressure, raise pid limits or fix runaway processes. Kubelet will mark the node Ready once the pressure condition clears.

Journey Context:
Several pods enter Pending and kubectl get nodes shows one node as NotReady. kubectl describe node shows Conditions: DiskPressure=True. SSHing to the node reveals the root partition is 98% full because container logs were never rotated. You truncate the largest log files and set up logrotate. The node returns to Ready after kubelet's next status update. The fix works because kubelet monitors node resources and proactively taints the node under pressure to prevent new scheduling; resolving the underlying resource shortage is the only way to restore Ready status.
