 Like a {{< glossary_tooltip term_id="deployment" >}}, a StatefulSet manages Pods that are based on an identical container spec. Unlike a Deployment, a StatefulSet maintains a sticky identity for each of their Pods. These pods are created from the same spec, but are not interchangeable&#58; each has a persistent identifier that it maintains across any rescheduling.

-和 {{< glossary_tooltip term_id="Deployment" >}} 相同的是，StatefulSet 管理了基于相同容器定义的一组 Pod。但和 Deployment 不同的是，StatefulSet 为它们的每个 Pod 维护了一个固定的 ID。这些 Pod 是基于相同的声明来创建的，但是不能相互替换：无论怎么调度，每个 Pod 都有一个永久不变的 ID。

-A StatefulSet operates under the same pattern as any other Controller. You define your desired state in a StatefulSet *object*, and the StatefulSet *controller* makes any necessary updates to get there from the current state.
+If you want to use storage volumes to provide persistence for your workload, you can use a StatefulSet as part of the solution. Although individual Pods in a StatefulSet are susceptible to failure, the persistent Pod identifiers make it easier to match existing volumes to the new Pods that replace any that have failed.

-StatefulSet 和其他控制器使用相同的工作模式。你在 StatefulSet *对象* 中定义你期望的状态，然后 StatefulSet 的 *控制器* 就会通过各种更新来达到那种你想要的状态。

+如果希望使用存储卷为工作负载提供持久性，可以使用状态集作为解决方案的一部分。尽管状态完整集中的单个Pod很容易出现故障，但持久的Pod标识符使得将现有卷与替换任何出现故障的新Pod相匹配变得更加容易。如果希望使用存储卷为工作负载提供持久性，可以使用状态集作为解决方案的一部分。尽管状态完整集中的单个Pod很容易出现故障，但持久的Pod标识符使得将现有卷与替换任何出现故障的新Pod相匹配变得更加容易。
