#### 硬驱逐阈值
硬驱逐阈值没有宽限期，一旦察觉，`kubelet`将立即采取行动回收关联的短缺资源。
如果满足硬驱逐阈值，`kubelet`将立即结束 pod 而不是优雅终止。
硬驱逐阈值没有宽限期，一旦察觉，`kubelet` 将立即采取行动回收关联的短缺资源。
如果满足硬驱逐阈值，`kubelet` 将立即结束 Pod 而不是体面地终止它们。
硬驱逐阈值的配置支持下列标记：
* `eviction-hard` 描述了驱逐阈值的集合（例如 `memory.available<1Gi`），如果满足条件将触发 pod 驱逐。
* `eviction-hard` 描述了驱逐阈值的集合（例如 `memory.available<1Gi`），如果满足条件将触发 Pod 驱逐。
`kubelet` 有如下所示的默认硬驱逐阈值：
* `memory.available<100Mi`
* `nodefs.available<10%`
* `nodefs.inodesFree<5%`
* `imagefs.available<15%`
在Linux节点上，默认值还包括 `nodefs.inodesFree<5％`。
