What Is Node Pressure?
Node pressure is a reported condition on a node indicating it is running short on a resource, expressed as flags like memory pressure, disk pressure, or PID pressure. When a pressure condition is set, the node may evict pods and the scheduler avoids placing new ones there. It is how the cluster recognizes a stressed node.
Why it matters
Pressure conditions are an early signal that a node is overcommitted and about to evict workloads. Watching them helps diagnose why CI pods get rescheduled or stuck pending.
