此功能目前处于 *beta* 状态，即：

<!--
This feature is currently in a *beta* state, meaning:
-->
<!--
* The version names contain beta (e.g. v2beta3).
* Code is well tested. Enabling the feature is considered safe. Enabled by default.
* Support for the overall feature will not be dropped, though details may change.
* The schema and/or semantics of objects may change in incompatible ways in a subsequent beta or stable release. When this happens, we will provide instructions for migrating to the next version. This may require deleting, editing, and re-creating API objects. The editing process may require some thought. This may require downtime for applications that rely on the feature.
* Recommended for only non-business-critical uses because of potential for incompatible changes in subsequent releases. If you have multiple clusters that can be upgraded independently, you may be able to relax this restriction.
* **Please do try our beta features and give feedback on them! After they exit beta, it may not be practical for us to make more changes.**

* 版本名称包含 beta (例如 v2beta3)。
* 代码经过了良好的测试，启用该特性被认为是安全的。默认启用，对整个特性的支持不会被删除，尽管细节可能会更改。
* 在后续 beta 或稳定版本中，对象的模式和/或语义可能以不兼容的方式发生变化。当这种情况发生时，我们将提供迁移到下一个版本的说明。这可能需要删除、编辑和重新创建 API 对象。编辑过程可能需要一些思考可能需要依赖该特性的应用程序停机。
* 建议仅用于非业务关键用途，因为后续版本中可能会出现不兼容的更改。如果您有多个可以独立升级的集群，那么您可能可以放松这个限制。
* **请尝试我们的测试版功能并给出反馈!在他们退出测试版后，我们可能无法进行更多更改。**
