Switch language name 'zh' to 'zh-cn'
This is the first step to rename 'zh' to 'zh-cn'. There are several reasons why we rename the language name.
- The upstream docsy theme changed the language name, leading to many warnings during site build;
The side-effect is that the i18n strings are no longer working.
- We believe renaming the language is the right thing to do, because this move can make room for other variants of Chinese language, such as 'zh-tw', 'zh-sg' etc.
There would be several follow-ups to this PR, such as fixing the intra-site links, adding redirects etc.
We will lock up changes to zh/zh-cn pages for the moment, until this one gets in.
This PR is based on commit cdad0a7342.

A WebHook is an HTTP callback: an HTTP POST that occurs when something happens; a simple event-notification via HTTP POST. A web application implementing WebHooks will POST a message to a URL when certain things happen.
|
||||
-->
|
||||
WebHook 是一种 HTTP 回调:某些条件下触发的 HTTP POST 请求;通过 HTTP POST 发送的简单事件通知。一个基于 web 应用实现的 WebHook 会在特定事件发生时把消息发送给特定的 URL。

Mode `Webhook` requires a file for HTTP configuration, specify by the

`Webhook` 模式需要一个 HTTP 配置文件,通过 `--authorization-webhook-config-file=SOME_FILENAME` 的参数声明。

<!--

The configuration file uses the [kubeconfig](/docs/tasks/access-application-cluster/configure-access-multiple-clusters/)

file format. Within the file "users" refers to the API Server webhook and
|

"clusters" refers to the remote service.

配置文件的格式使用 [kubeconfig](/zh/docs/tasks/access-application-cluster/configure-access-multiple-clusters/)。

|

<!--
|
||||
When faced with an authorization decision, the API Server POSTs a JSON-
|
||||
serialized `authorization.k8s.io/v1beta1` `SubjectAccessReview` object describing the
|
||||
action. This object contains fields describing the user attempting to make the
|
||||
request, and either details about the resource being accessed or requests
|
||||
attributes.
|
||||
-->
|
||||
在做认证决策时,API 服务器会 POST 一个 JSON 序列化的 `authorization.k8s.io/v1beta1` `SubjectAccessReview`
|
||||
对象来描述这个动作。这个对象包含了描述用户请求的字段,同时也包含了需要被访问资源或请求特征的具体信息。
|
||||
|
||||
<!--
|
||||
Note that webhook API objects are subject to the same [versioning compatibility rules](/docs/concepts/overview/kubernetes-api/)
|
||||
as other Kubernetes API objects. Implementers should be aware of looser
|
||||
compatibility promises for beta objects and check the "apiVersion" field of the
|
||||
request to ensure correct deserialization. Additionally, the API Server must
|
||||
enable the `authorization.k8s.io/v1beta1` API extensions group (`--runtime-config=authorization.k8s.io/v1beta1=true`).
|
||||
-->
|
||||
需要注意的是 webhook API 对象与其他 Kubernetes API 对象一样都同样都遵从[版本兼容规则](/zh/docs/concepts/overview/kubernetes-api/)。
|
||||
实施人员应该了解 beta 对象的更宽松的兼容性承诺,同时确认请求的 "apiVersion" 字段能被正确地反序列化。
|
||||
此外,API 服务器还必须启用 `authorization.k8s.io/v1beta1` API 扩展组 (`--runtime-config=authorization.k8s.io/v1beta1=true`)。

The remote service is expected to fill the `status` field of

the request and respond to either allow or disallow access. The response body's

`spec` field is ignored and may be omitted. A permissive response would return:

{

<!--
|

For disallowing access there are two methods.
|

-->
|
||||
为了禁止访问,有两种方法。
|
||||
|
||||
<!--
|
||||
The first method is preferred in most cases, and indicates the authorization
|
||||
webhook does not allow, or has "no opinion" about the request, but if other
|
||||
authorizers are configured, they are given a chance to allow the request.
|
||||
If there are no other authorizers, or none of them allow the request, the
|
||||
request is forbidden. The webhook would return:
|
||||
-->
|
||||
在大多数情况下,第一种方法是首选方法,它指示授权 webhook 不允许或对请求 “无意见”。
|
||||
但是,如果配置了其他授权者,则可以给他们机会允许请求。如果没有其他授权者,或者没有一个授权者,则该请求被禁止。webhook 将返回:
|
||||
|
||||
```json
|
||||
{
|
||||
"apiVersion": "authorization.k8s.io/v1beta1",
|
||||
"kind": "SubjectAccessReview",
|
||||
"status": {
|
||||
"allowed": false,
|
||||
"reason": "user does not have read access to the namespace"
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
<!--
|
||||
The second method denies immediately, short-circuiting evaluation by other
|
||||
configured authorizers. This should only be used by webhooks that have
|
||||
detailed knowledge of the full authorizer configuration of the cluster.
|
||||
The webhook would return:
|
||||
-->
|
||||
第二种方法立即拒绝其他配置的授权者进行短路评估。仅应由对集群的完整授权者配置有详细了解的 webhook 使用。webhook 将返回:
|
||||
|
||||
```json
|
||||
{
|
||||
"apiVersion": "authorization.k8s.io/v1beta1",
|
||||
"kind": "SubjectAccessReview",

Non-resource paths include: `/api`, `/apis`, `/metrics`,

`/logs`, `/debug`, `/healthz`, `/livez`, `/openapi/v2`, `/readyz`, and

`/version.` Clients require access to `/api`, `/api/*`, `/apis`, `/apis/*`,

and `/version` to discover what resources and versions are present on the server.

Access to other non-resource paths can be disallowed without restricting access

to the REST api.

非资源类的路径包括:`/api`、`/apis`、`/metrics`、`/logs`、`/debug`、
|
||||
`/healthz`、`/livez`、`/openapi/v2`、`/readyz`、和 `/version`。
|
||||
客户端需要访问 `/api`、`/api/*`、`/apis`、`/apis/*` 和 `/version` 以便
|
||||
能发现服务器上有什么资源和版本。对于其他非资源类的路径访问在没有 REST API 访问限制的情况下拒绝。
