+
+Example: `cluster-autoscaler.kubernetes.io/safe-to-evict: "true"`
+
+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.
