+Used on: Pod
+
+When this annotation is set to `"true"`, the cluster autoscaler is allowed to evict a Pod
+even if other rules would normally prevent that.
+The cluster autoscaler never evicts Pods that have this annotation explicitly set to
+`"false"`; you could set that on an important Pod that you want to keep running.
+If this annotation is not set then the cluster autoscaler follows its Pod-level behavior.

+
+当这个注解设置为 `"true"` 时，即使其他规则通常会阻止驱逐操作，也会允许该集群自动扩缩器驱逐一个 Pod。
+集群自动扩缩器从不驱逐将此注解显式设置为 `"false"` 的 Pod；你可以针对要保持运行的重要 Pod 设置此注解。
+如果未设置此注解，则集群自动扩缩器将遵循其 Pod 级别的行为。
