Node-pressure eviction is the process by which the kubelet proactively terminates pods to reclaim resources on nodes.
The kubelet monitors resources like CPU, memory, disk space, and filesystem inodes on your cluster's nodes. When one or more of these resources reach specific consumption levels, the kubelet can proactively fail one or more pods on the node to reclaim resources and prevent starvation.
During a node-pressure eviction, the kubelet sets the PodPhase for the selected pods to Failed.
