Eviction — Certified Kubernetes Administrator (CKA) Practice Questions
Eviction in Kubernetes refers to the process by which the kubelet terminates pods on a node when that node is under resource pressure, such as low memory or disk space, in order to reclaim resources and maintain node stability. There are two distinct contexts: soft and hard eviction thresholds configured in the kubelet, and API-initiated eviction used during node drain operations. CKA candidates need to understand how eviction policies interact with resource requests, limits, and Quality of Service classes, because eviction order and thresholds are common exam topics in the workload and scheduling domain.
