<!--
This page describes how kubelet managed Containers can use the Container lifecycle hook framework
to run code triggered by events during their management lifecycle.
-->
这个页面描述了 kubelet 管理的容器如何使用容器生命周期钩子框架来运行在其管理生命周期中由事件触发的代码。
{{% /capture %}}
{{% capture body %}}
<!--
## Overview
-->
## 概述
<!--
Analogous to many programming language frameworks that have component lifecycle hooks, such as Angular,
Kubernetes provides Containers with lifecycle hooks.
The hooks enable Containers to be aware of events in their management lifecycle
and run code implemented in a handler when the corresponding lifecycle hook is executed.
-->
类似于许多具有生命周期钩子组件的编程语言框架,例如Angular,Kubernetes为容器提供了生命周期钩子。
钩子使容器能够了解其管理生命周期中的事件,并在执行相应的生命周期钩子时运行在处理程序中实现的代码。
<!--
## Container hooks
-->
## 容器钩子
<!--
There are two hooks that are exposed to Containers:
-->
有两个钩子暴露在容器中:
`PostStart`
<!--
This hook executes immediately after a container is created.
However, there is no guarantee that the hook will execute before the container ENTRYPOINT.
No parameters are passed to the handler.
-->
这个钩子在创建容器之后立即执行。
但是,不能保证钩子会在容器入口点之前执行。
没有参数传递给处理程序。
`PreStop`
<!--
This hook is called immediately before a container is terminated.
It is blocking, meaning it is synchronous,
so it must complete before the call to delete the container can be sent.
No parameters are passed to the handler.
-->
在容器终止之前立即调用此钩子。
它是阻塞的,同时也是同步的,因此它必须在删除容器的调用之前完成。
没有参数传递给处理程序。
<!--
A more detailed description of the termination behavior can be found in
[Termination of Pods](/docs/concepts/workloads/pods/pod/#termination-of-pods).
-->
有关终止行为的更详细描述,请参见[终止 Pod](/docs/concepts/workloads/pods/pod/#termination-of-pods)。
<!--
### Hook handler implementations
-->
### 钩子处理程序的实现
<!--
Containers can access a hook by implementing and registering a handler for that hook.
There are two types of hook handlers that can be implemented for Containers:
-->
容器可以通过实现和注册该钩子的处理程序来访问该钩子。
针对容器,有两种类型的钩子处理程序可供实现:
<!--
* Exec - Executes a specific command, such as `pre-stop.sh`, inside the cgroups and namespaces of the Container.
Resources consumed by the command are counted against the Container.
* HTTP - Executes an HTTP request against a specific endpoint on the Container.
-->
* Exec - 执行一个特定的命令,例如 `pre-stop.sh`,在容器的 cgroups 和名称空间中。
命令所消耗的资源根据容器进行计算。
* HTTP - 对容器上的特定端点执行 HTTP 请求。
<!--
### Hook handler execution
-->
### 钩子处理程序执行
<!--
When a Container lifecycle management hook is called,
the Kubernetes management system executes the handler in the Container registered for that hook. 
-->
当调用容器生命周期管理钩子时,Kubernetes 管理系统在为该钩子注册的容器中执行处理程序。
<!--
Hook handler calls are synchronous within the context of the Pod containing the Container.
This means that for a `PostStart` hook,
the Container ENTRYPOINT and hook fire asynchronously.
However, if the hook takes too long to run or hangs,
the Container cannot reach a `running` state.
-->
钩子处理程序调用在包含容器的 Pod 上下文中是同步的。
这意味着对于 `PostStart` 钩子,容器入口点和钩子异步触发。
但是,如果钩子运行或挂起的时间太长,则容器无法达到 `running` 状态。
<!--
The behavior is similar for a `PreStop` hook.
If the hook hangs during execution,
the Pod phase stays in a `Terminating` state and is killed after `terminationGracePeriodSeconds` of pod ends.
If a `PostStart` or `PreStop` hook fails,
it kills the Container.
-->
行为与 `PreStop` 钩子的行为类似。
如果钩子在执行过程中挂起,Pod 阶段将保持在 `Terminating` 状态,并在 Pod 结束的 `terminationGracePeriodSeconds` 之后被杀死。
如果 `PostStart``PreStop` 钩子失败,它会杀死容器。
<!--
Users should make their hook handlers as lightweight as possible.
There are cases, however, when long running commands make sense,
such as when saving state prior to stopping a Container.
-->
用户应该使他们的钩子处理程序尽可能的轻量级。
但也需要考虑长时间运行的命令也很有用的情况,比如在停止容器之前保存状态。
<!--
### Hook delivery guarantees
-->
### 钩子寄送保证
<!--
Hook delivery is intended to be *at least once*,
which means that a hook may be called multiple times for any given event,
such as for `PostStart` or `PreStop`.
It is up to the hook implementation to handle this correctly.
-->
钩子的寄送应该是*至少一次*,这意味着对于任何给定的事件,例如 `PostStart``PreStop`,钩子可以被调用多次。
如何正确处理,是钩子实现所要考虑的问题。
<!--
Generally, only single deliveries are made.
If, for example, an HTTP hook receiver is down and is unable to take traffic,
there is no attempt to resend.
In some rare cases, however, double delivery may occur.
For instance, if a kubelet restarts in the middle of sending a hook,
the hook might be resent after the kubelet comes back up.
-->
通常情况下,只会进行单次寄送。
例如,如果 HTTP 钩子接收器宕机,无法接收流量,则不会尝试重新发送。
然而,偶尔也会发生重复寄送的可能。
例如,如果 kubelet 在发送钩子的过程中重新启动,钩子可能会在 kubelet 恢复后重新发送。
<!--
### Debugging Hook handlers
-->
### 调试钩子处理程序
<!--
The logs for a Hook handler are not exposed in Pod events.
If a handler fails for some reason, it broadcasts an event.
For `PostStart`, this is the `FailedPostStartHook` event,
and for `PreStop`, this is the `FailedPreStopHook` event.
You can see these events by running `kubectl describe pod <pod_name>`.
Here is some example output of events from running this command:
-->
钩子处理程序的日志不会在 Pod 事件中公开。
如果处理程序由于某种原因失败,它将播放一个事件。
对于 `PostStart`,这是 `FailedPostStartHook` 事件,对于 `PreStop`,这是 `FailedPreStopHook` 事件。
您可以通过运行 `kubectl describe pod <pod_name>` 命令来查看这些事件。
下面是运行这个命令的一些事件输出示例:

## RuntimeClass
<!--
RuntimeClass is an alpha feature for selecting the container runtime configuration to use to run a
pod's containers.
-->
RuntimeClass 是一个 alpha 功能,用来选择运行 pod 中容器的容器运行时配置。
<!--
### Set Up
-->
### 设置
<!--
As an early alpha feature, there are some additional setup steps that must be taken in order to use
the RuntimeClass feature:
-->
作为一个处于早期状态的 alpha 特性,必须要完成以下步骤才能使用 RuntimeClass 功能:
<!--
1. Enable the RuntimeClass feature gate (on apiservers & kubelets, requires version 1.12+)
2. Install the RuntimeClass CRD
3. Configure the CRI implementation on nodes (runtime dependent)
4. Create the corresponding RuntimeClass resources
-->
1. 开启 RuntimeClass 特性门控(在 apiservers kubelets 上,需要 1.12 及以上版本)
2. 安装 RuntimeClass CRD
3. 在节点上配置 CRI 的实现(取决于所选的运行时)
4. 创建相应的 RuntimeClass 资源
<!--
#### 1. Enable the RuntimeClass feature gate
-->
#### 1. 开启 RuntimeClass 特性门控
<!--
See [Feature Gates](/docs/reference/command-line-tools-reference/feature-gates/) for an explanation
of enabling feature gates. The RuntimeClass feature gate must be enabled on apiservers _and_ kubelets.
-->
参见[特性门控](/docs/reference/command-line-tools-reference/feature-gates/)文档了解如何开启特定的特性门控。
`RuntimeClass` 特性门控必须在 apiservers __ kubelets 上同时开启,才能使用。
<!--
#### 2. Install the RuntimeClass CRD
-->
#### 2. 安装 RuntimeClass CRD
<!--
The RuntimeClass [CustomResourceDefinition][/docs/tasks/access-kubernetes-api/custom-resources/custom-resource-definitions/] (CRD) can be found in the addons directory of the
Kubernetes git repo:

可以在 Kubernetes git 仓库的 addons 目录中找到
RuntimeClass [CustomResourceDefinition (CRD)](/docs/tasks/access-kubernetes-api/custom-resources/custom-resource-definitions/) 的定义:
https://github.com/kubernetes/kubernetes/tree/release-1.12/cluster/addons/runtimeclass/runtimeclass_crd.yaml
<!--
Install the CRD with `kubectl apply -f runtimeclass_crd.yaml`.
-->
使用 `kubectl apply -f runtimeclass_crd.yaml` 命令安装 CRD。
<!--
#### 3. Configure the CRI implementation on nodes
-->
#### 3. 在节点上配置 CRI 实现
<!--
The configurations to select between with RuntimeClass are CRI implementation dependent. See the
corresponding documentation for your CRI implementation for how to configure. As this is an alpha
feature, not all CRIs support multiple RuntimeClasses yet.
-->
各 RuntimeClass 所支持的配置选项取决于 CRI 的实现本身。
请参阅 CRI 实现的相应文档了解具体如何配置。
由于这是一个 alpha 特性功能,并非所有 CRI 都支持多个 RuntimeClass。
<!--
RuntimeClass currently assumes a homogeneous node configuration across the cluster
(which means that all nodes are configured the same way with respect to container runtimes). Any heterogeneity (varying configurations) must be
managed independently of RuntimeClass through scheduling features
(see [Assigning Pods to Nodes](/docs/concepts/configuration/assign-pod-node/)).
-->
{{< note >}}
RuntimeClass 当前假设的是集群中的节点配置是同构的(换言之,所有的节点在容器运行时方面的配置是相同的)。
任何异构性(不同的配置)必须通过调度功能在 RuntimeClass 之外单独管理(请参阅[在节点上分配 Pods](/docs/concepts/configuration/assign-pod-node/))。
{{< /note >}}
<!--
The configurations have a corresponding `RuntimeHandler` name, referenced by the RuntimeClass. The
RuntimeHandler must be a valid DNS-1123 subdomain (alpha-numeric characters, `-`, or `.`).
-->
所有这些配置都具有相应的 `RuntimeHandler` 名,并被 RuntimeClass 引用。
RuntimeHandler 必须是有效的 DNS-1123 子域(字母数字字符、`-``.`)。
<!--
#### 4. Create the corresponding RuntimeClass resources
-->
#### 4. 创建相应的 RuntimeClass 资源
<!--
The configurations setup in step 3 should each have an associated `RuntimeHandler` name, which
identifies the configuration. For each RuntimeHandler (and optionally the empty `""` handler),
create a corresponding RuntimeClass object
.-->
步骤 3 中的配置设置应该有相应的 `RuntimeHandler` 名,用于标识配置。
对应每个 RuntimeHandler(以及 `""` 所代表的空处理程序),都创建相应的 RuntimeClass 对象。
<!--The RuntimeClass resource currently only has 2 significant fields: the RuntimeClass name
(`metadata.name`) and the RuntimeHandler (`spec.runtimeHandler`). The object definition looks like this:
-->
RuntimeClass 资源当前只有两个重要的字段:RuntimeClass 名 (`metadata.name`) 和 RuntimeHandler (`spec.runtimeHandler`)。
对象定义如下所示:
```yaml
apiVersion: node.k8s.io/v1alpha1 # 在 node.k8s.io API 中对 RuntimeClass 进行定义
kind: RuntimeClass
metadata:
name: myclass # 引用 RuntimeClass
# RuntimeClass 是不属于任何名字空间的资源
spec:
runtimeHandler: myconfiguration # 给出 CRI 配置的名称
```
<!--
It is recommended that RuntimeClass write operations (create/update/patch/delete) be
restricted to the cluster administrator. This is typically the default. See [Authorization
Overview](/docs/reference/access-authn-authz/authorization/) for more details.
-->
{{< note >}}
建议将 RuntimeClass 写操作(create、update、patch 和 delete)限定于集群管理员使用。
通常这是默认配置。参阅[授权概述](/docs/reference/access-authn-authz/authorization/)了解更多信息。
{{< /note >}}
<!--
### Usage
Once RuntimeClasses are configured for the cluster, using them is very simple. Specify a
`runtimeClassName` in the Pod spec. For example:
-->
### 使用说明
一旦完成集群中 RuntimeClasses 的配置,使用起来非常简便。
在 Pod spec 中指定 `runtimeClassName` 即可。例如:
```yaml
apiVersion: v1
kind: Pod
metadata:
name: mypod
spec:
runtimeClassName: myclass
# ...
```
<!--This will instruct the Kubelet to use the named RuntimeClass to run this pod. If the named
RuntimeClass does not exist, or the CRI cannot run the corresponding handler, the pod will enter the
`Failed` terminal [phase](/docs/concepts/workloads/pods/pod-lifecycle/#pod-phase). Look for a
corresponding [event](/docs/tasks/debug-application-cluster/debug-application-introspection/) for an
error message.-->
这一设置会告诉 Kubelet 使用所指的 RuntimeClass 来运行该 pod。
如果所指的 RuntimeClass 不存在或者 CRI 无法运行相应的 handler,那么 pod 将会进入 `Failed` 终止[阶段](/docs/concepts/workloads/pods/pod-lifecycle/#pod-phase)。
你可以查看相应的[事件](/docs/tasks/debug-application-cluster/debug-application-introspection/),获取出错信息。
<!--
If no `runtimeClassName` is specified, the default RuntimeHandler will be used, which is equivalent
to the behavior when the RuntimeClass feature is disabled.
-->
如果未指定 `runtimeClassName` ,则将使用默认的 RuntimeHandler,相当于禁用 RuntimeClass 功能特性。
