## Eviction Policy
The {{< glossary_tooltip text="Kubelet" term_id="kubelet" >}} can proactively monitor for and prevent total starvation of a
compute resource. In those cases, the `kubelet` can reclaim the starved
resource by proactively failing one or more Pods. When the `kubelet` fails
a Pod, it terminates all of its containers and transitions its `PodPhase` to `Failed`.
If the evicted Pod is managed by a Deployment, the Deployment will create another Pod
to be scheduled by Kubernetes.

## 驱逐策略 {#eviction-policy}
{{< glossary_tooltip text="Kubelet" term_id="kubelet" >}} 能够主动监测和防止计算资源的全面短缺。
在资源短缺的情况下,`kubelet` 可以主动地结束一个或多个 Pod 以回收短缺的资源。
`kubelet` 结束一个 Pod 时,它将终止 Pod 中的所有容器,而 Pod 的 `Phase` 将变为 `Failed`
如果被驱逐的 Pod 由 Deployment 管理,这个 Deployment 会创建另一个 Pod 给 Kubernetes 来调度。
