<!--
## Using StatefulSets
StatefulSets are valuable for applications that require one or more of the
following.
* Stable, unique network identifiers.
* Stable, persistent storage.
* Ordered, graceful deployment and scaling.
* Ordered, automated rolling updates.
In the above, stable is synonymous with persistence across Pod (re)scheduling.
If an application doesn't require any stable identifiers or ordered deployment,
deletion, or scaling, you should deploy your application using a workload object
that provides a set of stateless replicas.
[Deployment](/docs/concepts/workloads/controllers/deployment/) or
[ReplicaSet](/docs/concepts/workloads/controllers/replicaset/) may be better suited to your stateless needs.
-->
## 使用 StatefulSets
StatefulSets 对于需要满足以下一个或多个需求的应用程序很有价值：
* 稳定的、唯一的网络标识符。
* 稳定的、持久的存储。
* 有序的、优雅的部署和缩放。
* 有序的、自动的滚动更新。
在上面，稳定意味着 Pod 调度或重调度的整个过程是有持久性的。如果应用程序不需要任何稳定的标识符或有序的部署、删除或伸缩，则应该使用由一组无状态的副本控制器提供的工作负载来部署应用程序，比如 [Deployment](/docs/concepts/workloads/controllers/deployment/) 或者 [ReplicaSet](/docs/concepts/workloads/controllers/replicaset/) 可能更适用于您的无状态需要。
<!--
## Limitations
* The storage for a given Pod must either be provisioned by a [PersistentVolume Provisioner](https://github.com/kubernetes/examples/tree/{{< param "githubbranch" >}}/staging/persistent-volume-provisioning/README.md) based on the requested `storage class`, or pre-provisioned by an admin.
* Deleting and/or scaling a StatefulSet down will *not* delete the volumes associated with the StatefulSet. This is done to ensure data safety, which is generally more valuable than an automatic purge of all related StatefulSet resources.
* StatefulSets currently require a [Headless Service](/docs/concepts/services-networking/service/#headless-services) to be responsible for the network identity of the Pods. You are responsible for creating this Service.
* StatefulSets do not provide any guarantees on the termination of pods when a StatefulSet is deleted. To achieve ordered and graceful termination of the pods in the StatefulSet, it is possible to scale the StatefulSet down to 0 prior to deletion.
* When using [Rolling Updates](#rolling-updates) with the default
[Pod Management Policy](#pod-management-policies) (`OrderedReady`),
it's possible to get into a broken state that requires
[manual intervention to repair](#forced-rollback).
-->
## 限制
* 给定 Pod 的存储必须由 [PersistentVolume 驱动](https://github.com/kubernetes/examples/tree/{{< param "githubbranch" >}}/staging/persistent-volume-provisioning/README.md) 基于所请求的 `storage class` 来提供，或者由管理员预先提供。
* 删除和／或收缩 StatefulSet 并*不会*删除它关联的存储卷。这样做是为了保证数据安全，它通常比自动清除 StatefulSet 所有相关的资源更有价值。
* StatefulSet 当前需要 [headless 服务](/docs/concepts/services-networking/service/#headless-services) 来负责 Pod 的网络标识。您需要负责创建此服务。
* 当删除 StatefulSets 时，StatefulSet 不提供任何终止 Pod 的保证。为了实现 StatefulSet 中的 Pod 可以有序和优雅的终止，可以在删除之前将 StatefulSet 缩放为 0。
* 在默认 [Pod 管理策略](#pod-management-policies)(`OrderedReady`) 时使用 [滚动更新](#rolling-updates)，可能进入需要 [人工干预](#forced-rollback) 才能修复的损坏状态。
<!--
## Components
The example below demonstrates the components of a StatefulSet.
* A Headless Service, named nginx, is used to control the network domain.
* The StatefulSet, named web, has a Spec that indicates that 3 replicas of the nginx container will be launched in unique Pods.
* The volumeClaimTemplates will provide stable storage using [PersistentVolumes](/docs/concepts/storage/persistent-volumes/) provisioned by a PersistentVolume Provisioner.
-->
## 组件
下面的示例演示了 StatefulSet 的组件。
* 名为 nginx 的无头服务用来控制网络域。
* 名为 web 的 StatefulSet 有一个 Spec，它表明将在单个 Pod 中启动 nginx 容器的 3 个副本。
* volumeClaimTemplates 将通过 [PersistentVolumes](/docs/concepts/storage/persistent-volumes/) 驱动提供的 PersistentVolume 来提供稳定的存储。

```
<!--
## Pod Selector
You must set the `.spec.selector` field of a StatefulSet to match the labels of its `.spec.template.metadata.labels`. Prior to Kubernetes 1.8, the `.spec.selector` field was defaulted when omitted. In 1.8 and later versions, failing to specify a matching Pod Selector will result in a validation error during StatefulSet creation.
-->
## Pod 选择器
您必须设置 StatefulSet 的 `.spec.selector` 字段来匹配它的`.spec.template.metadata.labels`标签。在 Kubernetes 1.8 版本之前，忽略`.spec.selector` 字段会提供默认设置。在 1.8 和以后的版本中，指定的 Pod 选择器匹配失败将在创建 StatefulSet 期间导致验证错误。
<!--
## Pod Identity
StatefulSet Pods have a unique identity that is comprised of an ordinal, a
stable network identity, and stable storage. The identity sticks to the Pod,
regardless of which node it's (re)scheduled on.
-->
## Pod 的身份
StatefulSet Pod 具有唯一的标识，该标识包括顺序标识、稳定的网络标识和稳定的存储。该标识和 Pod 是绑定的，不管它被调度在哪个节点上。
<!--
### Ordinal Index
For a StatefulSet with N replicas, each Pod in the StatefulSet will be
assigned an integer ordinal, from 0 up through N-1, that is unique over the Set.
-->
### 有序索引
对于具有 N 个副本的 StatefulSet，StatefulSet 中的每个 Pod 将被分配一个整数序号，从 0 到 N-1，该序号在 StatefulSet 上是唯一的。
<!--
### Stable Network ID
Each Pod in a StatefulSet derives its hostname from the name of the StatefulSet
and the ordinal of the Pod. The pattern for the constructed hostname
is `$(statefulset name)-$(ordinal)`. The example above will create three Pods
named `web-0,web-1,web-2`.
A StatefulSet can use a [Headless Service](/docs/concepts/services-networking/service/#headless-services)
to control the domain of its Pods. The domain managed by this Service takes the form:
`$(service name).$(namespace).svc.cluster.local`, where "cluster.local" is the
cluster domain.
As each Pod is created, it gets a matching DNS subdomain, taking the form:
`$(podname).$(governing service domain)`, where the governing service is defined
by the `serviceName` field on the StatefulSet.
-->
### 稳定的网络 ID
StatefulSet 中的每个 Pod 根据 StatefulSet 的名称和 Pod 的序号派生出它的主机名。组合主机名的格式为`$(statefulset name)-$(ordinal)`。上例将会创建三个名称为`web-0,web-1,web-2`的三个 Pod。
StatefulSet 可以使用 [headless 服务](/docs/concepts/services-networking/service/#headless-services) 控制它的 Pod 的网络域。管理域的这个服务的格式为：
`$(service name).$(namespace).svc.cluster.local`，其中`cluster.local`是集群域。
一旦每个 Pod 创建成功，就会得到一个匹配的 DNS 子域，格式为：`$(podname).$(governing service domain)`，其中管理服务由 StatefulSet 的 `serviceName` 域来定义。
<!--
Here are some examples of choices for Cluster Domain, Service name,
StatefulSet name, and how that affects the DNS names for the StatefulSet's Pods.
-->
下面给出一些选择集群域、服务名、StatefulSet 名、及其怎样影响 StatefulSet 的 Pod 上的 DNS 名称的示例：
Cluster Domain | Service (ns/name) | StatefulSet (ns/name) | StatefulSet Domain | Pod DNS | Pod Hostname |
-------------- | ----------------- | ----------------- | -------------- | ------- | ------------ |
cluster.local | default/nginx | default/web | nginx.default.svc.cluster.local | web-{0..N-1}.nginx.default.svc.cluster.local | web-{0..N-1} |
cluster.local | foo/nginx | foo/web | nginx.foo.svc.cluster.local | web-{0..N-1}.nginx.foo.svc.cluster.local | web-{0..N-1} |
kube.local | foo/nginx | foo/web | nginx.foo.svc.kube.local | web-{0..N-1}.nginx.foo.svc.kube.local | web-{0..N-1} |
{{< note >}}
<!--
**Note:** Cluster Domain will be set to `cluster.local` unless
[otherwise configured](/docs/concepts/services-networking/dns-pod-service/#how-it-works).
-->
**注意** 集群域会被设置为 `cluster.local` 除非有[其他配置](/docs/concepts/services-networking/dns-pod-service/#how-it-works)。
{{< /note >}}
<!--
### Stable Storage
Kubernetes creates one [PersistentVolume](/docs/concepts/storage/persistent-volumes/) for each
VolumeClaimTemplate. In the nginx example above, each Pod will receive a single PersistentVolume
with a StorageClass of `my-storage-class` and 1 Gib of provisioned storage. If no StorageClass
is specified, then the default StorageClass will be used. When a Pod is (re)scheduled
onto a node, its `volumeMounts` mount the PersistentVolumes associated with its
PersistentVolume Claims. Note that, the PersistentVolumes associated with the
Pods' PersistentVolume Claims are not deleted when the Pods, or StatefulSet are deleted.
This must be done manually.
-->
### 稳定的存储
Kubernetes 为每个 VolumeClaimTemplate 创建一个 [PersistentVolume](/docs/concepts/storage/persistent-volumes/)。在上面的 nginx 示例中，每个 Pod 将会得到基于 StorageClass `my-storage-class` 提供的 1 Gib 的 PersistentVolume。如果没有声明 StorageClass，就会使用默认的 StorageClass。当一个 Pod 被安排到节点上时，它的 `volumeMounts` 挂载了与其 PersistentVolumeClaims 相关联的 PersistentVolume。请注意，当 Pod 或者 StatefulSet 被删除时，与 PersistentVolumeClaims 相关联的 PersistentVolume 并不会被删除。要删除它必须通过手动方式来完成。
<!--
### Pod Name Label
When the StatefulSet {{< glossary_tooltip term_id="controller" >}} creates a Pod,
it adds a label, `statefulset.kubernetes.io/pod-name`, that is set to the name of
the Pod. This label allows you to attach a Service to a specific Pod in
the StatefulSet.
-->
### Pod 名称标签
当 StatefulSet {{< glossary_tooltip term_id="controller" >}} 创建 Pod 时，它会添加一个标签 `statefulset.kubernetes.io/pod-name`，该标签设置为 Pod 名称。这个标签允许您给 StatefulSet 中的特定 Pod 绑定一个 Service。
<!--
## Deployment and Scaling Guarantees
* For a StatefulSet with N replicas, when Pods are being deployed, they are created sequentially, in order from {0..N-1}.
* When Pods are being deleted, they are terminated in reverse order, from {N-1..0}.
* Before a scaling operation is applied to a Pod, all of its predecessors must be Running and Ready.
* Before a Pod is terminated, all of its successors must be completely shutdown.
-->
## 部署和伸缩保证
* 对于包含 N 个 副本的 StatefulSet，当部署 Pod 时，它们是依次创建的，顺序为`0..N-1`。
* 当删除 Pod 时，它们是逆序终止的，顺序为`N-1..0`。
* 在将缩放操作应用到 Pod 之前，它前面的所有 Pod 必须是 Running 和 Ready 状态。
* 在 Pod 终止之前，所有的继任者必须完全关闭。
<!--
The StatefulSet should not specify a `pod.Spec.TerminationGracePeriodSeconds` of 0. This practice is unsafe and strongly discouraged. For further explanation, please refer to [force deleting StatefulSet Pods](/docs/tasks/run-application/force-delete-stateful-set-pod/).
-->
StatefulSet 不应该声明 `pod.Spec.TerminationGracePeriodSeconds` 为 0。这种做法是不安全的，要强烈阻止。更多的解释请参考 [强制删除 StatefulSet Pods](/docs/tasks/run-application/force-delete-stateful-set-pod/)。
<!--
When the nginx example above is created, three Pods will be deployed in the order
web-0, web-1, web-2. web-1 will not be deployed before web-0 is
[Running and Ready](/docs/user-guide/pod-states/), and web-2 will not be deployed until
web-1 is Running and Ready. If web-0 should fail, after web-1 is Running and Ready, but before
web-2 is launched, web-2 will not be launched until web-0 is successfully relaunched and
becomes Running and Ready.
-->
在上面的 nginx 示例被创建后，会按照 web-0、web-1、web-2 的顺序部署三个 Pod。在 web-0 进入 [Running 和 Ready](/docs/user-guide/pod-states/) 状态前不会部署 web-1。在 web-1 进入 Running 和 Ready 状态前不会部署 web-2。如果 web-1 已经处于 Running 和 Ready 状态，而 web-2 尚未部署，在此期间发生了 web-0 运行失败，那么 web-2 将不会被部署，要等到 web-0 部署完成并进入 Running 和 Ready 状态后，才会部署 web-2。
<!--
If a user were to scale the deployed example by patching the StatefulSet such that
`replicas=1`, web-2 would be terminated first. web-1 would not be terminated until web-2
is fully shutdown and deleted. If web-0 were to fail after web-2 has been terminated and
is completely shutdown, but prior to web-1's termination, web-1 would not be terminated
until web-0 is Running and Ready.
-->
如果用户想将示例中的 StatefulSet 收缩为 `replicas=1`，首先被终止的是 web-2。在 web-2 没有被完全停止和删除前，web-1 不会被终止。当 web-2 已被终止和删除、web-1 尚未被终止，如果在此期间发生 web-0 运行失败，那么就不会终止 web-1，必须等到 web-0 进入 Running 和 Ready 状态后才会终止 web-1。

### Pod Management Policies
In Kubernetes 1.7 and later, StatefulSet allows you to relax its ordering guarantees while
preserving its uniqueness and identity guarantees via its `.spec.podManagementPolicy` field.
#### OrderedReady Pod Management
`OrderedReady` pod management is the default for StatefulSets. It implements the behavior
described [above](#deployment-and-scaling-guarantees).
#### Parallel Pod Management
`Parallel` pod management tells the StatefulSet controller to launch or
terminate all Pods in parallel, and to not wait for Pods to become Running
and Ready or completely terminated prior to launching or terminating another
Pod.
-->
### Pod 管理策略 {#pod-management-policies}
在 Kubernetes 1.7 及以后的版本中，StatefulSet 允许您放松其排序保证，同时通过它的 `.spec.podManagementPolicy` 域保持其唯一性和身份保证。
#### 有序的 Pod 管理
`有序的` Pod 管理是 StatefulSet 的默认功能。它实现了 [上面](#deployment-and-scaling-guarantees)描述的行为。
#### 并行的 Pod 管理
`并行` Pod 管理让 StatefulSet 控制器并行的启动或终止所有的 Pod，启动或者终止其他 Pod 前，无需等待 Pod 进入 Running 和 ready 或者完全停止状态。
<!--
## Update Strategies
In Kubernetes 1.7 and later, StatefulSet's `.spec.updateStrategy` field allows you to configure
and disable automated rolling updates for containers, labels, resource request/limits, and
annotations for the Pods in a StatefulSet.
-->
## 更新策略
在 Kubernetes 1.7 及以后的版本中，StatefulSet 的 `.spec.updateStrategy` 字段让您可以配置和禁用掉自动滚动更新 Pod 的容器、标签、资源请求／限制、以及注解。
<!--
### On Delete
The `OnDelete` update strategy implements the legacy (1.6 and prior) behavior. When a StatefulSet's
`.spec.updateStrategy.type` is set to `OnDelete`, the StatefulSet controller will not automatically
update the Pods in a StatefulSet. Users must manually delete Pods to cause the controller to
create new Pods that reflect modifications made to a StatefulSet's `.spec.template`.
-->
### On Delete
`OnDelete` 更新策略实现了 1.6 及以前版本的历史遗留行为。当 StatefulSet 的 `.spec.updateStrategy.type` 设置为 `OnDelete` 时，它的控制器将不会自动更新 StatefulSet 中的 Pod。用户必须手动删除 Pod 以便让控制器创建新的 Pod，以此来对 StatefulSet 的 `.spec.template` 的变动作出反应。
<!--
### Rolling Updates
The `RollingUpdate` update strategy implements automated, rolling update for the Pods in a
StatefulSet. It is the default strategy when `.spec.updateStrategy` is left unspecified. When a StatefulSet's `.spec.updateStrategy.type` is set to `RollingUpdate`, the
StatefulSet controller will delete and recreate each Pod in the StatefulSet. It will proceed
in the same order as Pod termination (from the largest ordinal to the smallest), updating
each Pod one at a time. It will wait until an updated Pod is Running and Ready prior to
updating its predecessor.
-->
### 滚动更新 {#rolling-updates}
`RollingUpdate` 更新策略对 StatefulSet 中的 Pod 执行自动的滚动更新。在没有声明`.spec.updateStrategy`时，`RollingUpdate`是默认配置。
当 StatefulSet 的 `.spec.updateStrategy.type` 被设置为 `RollingUpdate` 时，StatefulSet 控制器会删除和重建 StatefulSet 中的每个 Pod。
它将按照与 Pod 终止相同的顺序（从最大序号到最小序号）进行，每次更新一个 Pod。它会等到被更新的 Pod 进入 Running 和 Ready 状态，然后再更新其前身。
<!--
#### Partitions
The `RollingUpdate` update strategy can be partitioned, by specifying a
`.spec.updateStrategy.rollingUpdate.partition`. If a partition is specified, all Pods with an
ordinal that is greater than or equal to the partition will be updated when the StatefulSet's
`.spec.template` is updated. All Pods with an ordinal that is less than the partition will not
be updated, and, even if they are deleted, they will be recreated at the previous version. If a
StatefulSet's `.spec.updateStrategy.rollingUpdate.partition` is greater than its `.spec.replicas`,
updates to its `.spec.template` will not be propagated to its Pods.
In most cases you will not need to use a partition, but they are useful if you want to stage an
update, roll out a canary, or perform a phased roll out.
-->
#### 分区
通过声明 `.spec.updateStrategy.rollingUpdate.partition`的方式，`RollingUpdate`更新策略可以实现分区。如果声明了一个分区，当 StatefulSet 的`.spec.template` 被更新时，所有序号大于等于该分区序号的 Pod 都会被更新。所有序号小于该分区序号的 Pod 都不会被更新，并且，即使他们被删除也会依据之前的版本进行重建。如果 StatefulSet 的 `.spec.updateStrategy.rollingUpdate.partition` 大于它的 `.spec.replicas`，对它的 `.spec.template` 的更新将不会传递到它的 Pod。
在大多数情况下，您不需要使用分区，但如果您希望进行阶段更新、执行金丝雀或执行分阶段展开，则这些分区会非常有用。
<!--
#### Forced Rollback
When using [Rolling Updates](#rolling-updates) with the default
[Pod Management Policy](#pod-management-policies) (`OrderedReady`),
it's possible to get into a broken state that requires manual intervention to repair.
If you update the Pod template to a configuration that never becomes Running and
Ready (for example, due to a bad binary or application-level configuration error),
StatefulSet will stop the rollout and wait.
In this state, it's not enough to revert the Pod template to a good configuration.
Due to a [known issue](https://github.com/kubernetes/kubernetes/issues/67250),
StatefulSet will continue to wait for the broken Pod to become Ready
(which never happens) before it will attempt to revert it back to the working
configuration.
After reverting the template, you must also delete any Pods that StatefulSet had
already attempted to run with the bad configuration.
StatefulSet will then begin to recreate the Pods using the reverted template.
-->
#### 强制回滚 {#forced-rollback}
在默认 [Pod 管理策略](#pod-management-policies)(`OrderedReady`) 时使用 [滚动更新](#rolling-updates) ，可能进入需要人工干预才能修复的损坏状态。
如果更新后 Pod 模板配置进入无法运行或就绪的状态（例如，由于错误的二进制文件或应用程序级配置错误），StatefulSet 将停止回滚并等待。
在这种状态下，仅将 Pod 模板还原为正确的配置是不够的。由于 [已知问题](https://github.com/kubernetes/kubernetes/issues/67250)，
StatefulSet 将继续等待损坏状态的 Pod 准备就绪（永远不会发生），然后再尝试将其恢复为正常工作配置。
恢复模板后，还必须删除 StatefulSet 尝试使用错误的配置来运行的 Pod。这样，StatefulSet 才会开始使用被还原的模板来重新创建 Pod。
