|

## 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 with a controller that
|
||||
provides a set of stateless replicas. Controllers such as
|
||||
[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，则应该使用一组无状态的副本控制器来部署应用程序，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
|
||||
|
||||
* StatefulSet was a beta resource prior to 1.9 and not available in any Kubernetes release prior to 1.5.
|
||||
* 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.
|
||||
-->
|
||||
|
||||
## 限制
|
||||
|
||||
* StatefulSet 在 1.9 版本之前属于 beta 资源，在 1.5 版本之前的任何 Kubernetes 版本中都不可用。
|
||||
* 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 [无头服务](/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。
|
||||
|
||||
<!--
|
||||
## 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.
|
||||
-->
|
||||
|
||||
### 序号索引
|
||||
|
||||
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 [无头服务](/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 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 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
|
||||
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。
