Kubernetes REST API 中的所有对象都通过名称和 UID 明确标识。

<!--
All objects in the Kubernetes REST API are unambiguously identified by a Name and a UID.
-->

对于用户提供的非惟一属性，Kubernetes 提供 [标签](/docs/user-guide/labels) 和
[注解](/docs/concepts/overview/working-with-objects/annotations/)。

<!--
For non-unique user-provided attributes, Kubernetes provides [labels](/docs/user-guide/labels) and [annotations](/docs/concepts/overview/working-with-objects/annotations/).
-->

查看 [标识设计文档](https://git.k8s.io/community/contributors/design-proposals/architecture/identifiers.md) 获取名称和 UID 的精确语法规则。

<!--
See the [identifiers design doc](https://git.k8s.io/community/contributors/design-proposals/architecture/identifiers.md) for the precise syntax rules for Names and UIDs.
