Scheduling, Preemption and Eviction [page]deterministic

concepts

In Kubernetes, scheduling refers to making sure that [Pods](#gloss:pod) are matched to [Nodes](#gloss:node) so that the [kubelet](#gloss:kubelet) can run them. Preemption is the process of terminating Pods with lower [Priority](#gloss:pod-priority) so that Pods with higher Priority can schedule on Nodes. Eviction is the process of terminating one or more Pods on Nodes.
