服务器将启动并开始对通用
API
端点提供服务：
$ curl -k https://localhost:443/healthz
ok
我们也可以尝试列出服务发现端点，但是结果并不令人满意，因为我们还没
创建一个
API
，所以返回的结果是空的：
$ curl -k https://localhost:443/apis
{
"kind": "APIGroupList",
"groups": []
}
从更高的层面来看：
•
我们用推荐的选项和配置启动了一个自定义
API
服务器。
•
我们有了一个标准的处理链，包括委托身份认证、委托授权和审计。
•
我们运行了一个
HTTPS
服务并能正确处理对通用端点的请求：
/logs
、
/metrics
、
/version
、
/healthz
和
/apis
。

内部类型和转换
现在我们已经配置好了一个可以运行的自定义
API
服务器，是时候实现真正
的
API
了。在开始之前，我们需要了解
API
版本有关的概念，以及
API
服务
器内部是如何处理它的。
每个
API
服务器都可以提供对多个资源和版本（见图
2-3
）的服务。有些资源
有多个版本，为了让一个资源的多版本共存成为可能，
API
服务器需要把资
源在多个版本之间进行转换。
