The Kubernetes {{< glossary_tooltip term_id="kube-apiserver" text="API server" >}} provides API endpoints to indicate the current status of the API server.
17+
This page describes these API endpoints and explains how you can use them.

Kubernetes {{< glossary_tooltip term_id="kube-apiserver" text="API 服务器" >}} 提供 API 端点以指示 API 服务器的当前状态。
20+
本文描述了这些 API 端点，并说明如何使用。

27+
<!--
28+
The Kubernetes API server provides 3 API endpoints (`healthz`, `livez` and `readyz`) to indicate the current status of the API server.
29+
The `healthz` endpoint is deprecated (since Kubernetes v1.16), and you should use the more specific `livez` and `readyz` endpoints instead.
30+
The `livez` endpoint can be used with the `--livez-grace-period` [flag](/docs/reference/command-line-tools-reference/kube-apiserver) to specify the startup duration.
31+
For a graceful shutdown you can specify the `--shutdown-delay-duration` [flag](/docs/reference/command-line-tools-reference/kube-apiserver) with the `/readyz` endpoint.
32+
Machines that check the `health`/`livez`/`readyz` of the API server should rely on the HTTP status code.
33+
A status code `200` indicates the API server is `healthy`/`live`/`ready`, depending of the called endpoint.
34+
The more verbose options shown below are intended to be used by human operators to debug their cluster or specially the state of the API server.
35+

36+
Kubernetes API 服务器提供 3 个 API 端点（`healthz`、`livez` 和 `readyz`）来表明 API 服务器的当前状态。
37+
`healthz` 端点已被弃用（自 Kubernetes v1.16 起），你应该使用更为明确的 `livez` 和 `readyz` 端点。
38+
`livez` 端点可与 `--livez-grace-period` [标志](/zh/docs/reference/command-line-tools-reference/kube-apiserver)一起使用，来指定启动持续时间。
39+
为了正常关机，你可以使用 `/readyz` 端点并指定 `--shutdown-delay-duration` [标志](/zh/docs/reference/command-line-tools-reference/kube-apiserver)。
40+
检查 API 服务器的 `health`/`livez`/`readyz` 端点的机器应依赖于 HTTP 状态代码。
41+
状态码 `200` 表示 API 服务器是 `healthy`、`live` 还是 `ready`，具体取决于所调用的端点。
42+
以下更详细的选项供操作人员使用，用来调试其集群或专门调试 API 服务器的状态。
43+
44+
<!-- The following examples will show how you can interact with the health API endpoints. -->
45+
以下示例将显示如何与运行状况 API 端点进行交互。
46+
47+
<!--
48+
For all endpoints you can use the `verbose` parameter to print out the checks and their status.
49+
This can be useful for a human operator to debug the current status of the Api server, it is not intended to be consumed by a machine:
50+
-->
51+
对于所有端点，都可以使用 `verbose` 参数来打印检查项以及检查状态。
52+
这对于操作人员调试 API 服务器的当前状态很有用，这些不打算给机器使用：
53+
54+
```shell
55+
curl -k https://localhost:6443/livez?verbose
56+
```
57+
58+
<!-- or from a remote host with authentication: -->
59+
或从具有身份验证的远程主机：
60+
61+
```shell
62+
kubectl get --raw='/readyz?verbose'
63+
```
64+
65+
<!-- The output will look like this: -->
66+
输出将如下所示：
67+
68+
```shell
69+

The Kubernetes API server also supports to exclude specific checks.

94+
Kubernetes API 服务器也支持排除特定的检查项。
95+
查询参数也可以像以下示例一样进行组合：

{{< feature-state state="alpha" >}}
131+
132+
<!--
133+
Each individual health check exposes an http endpoint and could can be checked individually.
134+
The schema for the individual health checks is `/livez/<healthcheck-name>` where `livez` and `readyz` and be used to indicate if you want to check the liveness or the readiness of the API server.
135+
The `<healthcheck-name>` path can be discovered using the `verbose` flag from above and take the path between `[+]` and `ok`.
136+
These individual health checks should not be consumed by machines but can be helpful for a human operator to debug a system:
137+
-->
138+
每个单独的健康检查都会公开一个 http 端点，并且可以单独检查。
139+
单个运行状况检查的模式为 `/livez/<healthcheck-name>`，其中 `livez` 和 `readyz` 表明你要检查的是 API 服务器是否存活或就绪。
140+
`<healthcheck-name>` 的路径可以通过上面的 `verbose` 参数发现 ，并采用 `[+]` 和 `ok` 之间的路径。
141+
这些单独的健康检查不应由机器使用，但对于操作人员调试系统而言，是有帮助的：
142+
143+
```shell
144+
curl -k https://localhost:6443/livez/etcd
145+
```
