Kubernetes features are enabled in your cluster.

<!--
You can turn these features on or off using the `--feature-gates` command line flag on each Kubernetes component.
Each Kubernetes component lets you enable or disable a set of feature gates that are relevant to that component.
The Kubernetes documentation lists all current 
[feature gates](/docs/reference/command-line-tools-reference/feature-gates/) and what they control.
-->
你可以在每个 Kubernetes 组件中使用 `--feature-gates` 命令行标志来开启或关闭这些特性。
每个 Kubernetes 组件都可以让你开启或关闭一组与该组件相关的特性门控。
Kubernetes 文档列出了当前所有的[特性门控](/zh-cn/docs/reference/command-line-tools-reference/feature-gates/)及其控制的内容。
