<!-- overview -->
<!--
This page contains an overview of the various feature gates an administrator
can specify on different Kubernetes components.

See [feature stages](#feature-stages) for an explanation of the stages for a feature.
-->

本页详述了管理员可以在不同的 Kubernetes 组件上指定的各种特性门控。

关于特性各个阶段的说明，请参见[特性阶段](#feature-stages)。

## Overview

## 概述

<!--
Feature gates are a set of key=value pairs that describe Kubernetes features.
You can turn these features on or off using the `--feature-gates` command line flag
on each Kubernetes component.
-->

特性门控是描述 Kubernetes 特性的一组键值对。您可以在 Kubernetes 的每一个组件中使用 `--feature-gates` flag 来启用或禁用这些特性。

<!--
Each Kubernetes component lets you enable or disable a set of feature gates that
are relevant to that component.
Use `-h` flag to see a full set of feature gates for all components.
To set feature gates for a component, such as kubelet, use the `--feature-gates` flag assigned to a list of feature pairs:
-->

每个 Kubernetes 组件都支持启用或禁用与该组件相关的一组特性门控。
使用 `-h` 参数来查看所有组件支持的完整特性门控。
要为诸如 kubelet 之类的组件设置特性门控，请使用 `--feature-gates` 参数，并向其传递一组特性：

```shell
--feature-gates="...,DynamicKubeletConfig=true"
```

<!--
The following tables are a summary of the feature gates that you can set on
different Kubernetes components.
-->

下表总结了在不同的 Kubernetes 组件上可以设置的特性门控。

<!--
- The "Since" column contains the Kubernetes release when a feature is introduced
  or its release stage is changed.
- The "Until" column, if not empty, contains the last Kubernetes release in which
  you can still use a feature gate.
- If a feature is in the Alpha or Beta state, you can find the feature listed
  in the [Alpha/Beta feature gate table](#feature-gates-for-alpha-or-beta-features).
- If a feature is stable you can find all stages for that feature listed in the
  [Graduated/Deprecated feature gate table](#feature-gates-for-graduated-or-deprecated-features).
- The [Graduated/Deprecated feature gate table](#feature-gates-for-graduated-or-deprecated-features)
  also lists deprecated and withdrawn features.
-->

- 引入特性或更改其发布阶段后，"Since" 列将包含 Kubernetes 版本。
- "Until" 列（如果不为空）包含最后一个 Kubernetes 版本，您仍可以在其中使用特性门控。
- 如果某个特性处于 Alpha 或 Beta 状态，您可以在 [Alpha 和 Beta 特性门控表](#feature-gates-for-alpha-or-beta-features)中找到该特性。
- 如果某个特性处于稳定状态，您可以在[毕业和废弃特性门控表](#feature-gates-for-graduated-or-deprecated-features).中找到该特性的所有阶段。
- [毕业和废弃特性门控表](#feature-gates-for-graduated-or-deprecated-features) 还列出了废弃的和已被移除的特性。

## Using a feature

### Feature stages
-->

## 使用特性

### 特性阶段

<!--
A feature can be in *Alpha*, *Beta* or *GA* stage.
An *Alpha* feature means:
-->

处于 *Alpha* 、*Beta* 、 *GA* 阶段的特性。

*Alpha* 特性代表：

<!--
* Disabled by default.
* Might be buggy. Enabling the feature may expose bugs.
* Support for feature may be dropped at any time without notice.
* The API may change in incompatible ways in a later software release without notice.
* Recommended for use only in short-lived testing clusters, due to increased
  risk of bugs and lack of long-term support.
-->

* 默认禁用。
* 可能有错误，启用此特性可能会导致错误。
* 随时可能删除对此特性的支持，恕不另行通知。
* 在以后的软件版本中，API 可能会以不兼容的方式更改，恕不另行通知。
* 建议将其仅用于短期测试中，因为开启特性会增加错误的风险，并且缺乏长期支持。

<!--
A *Beta* feature means:
-->

*Beta* 特性代表：

<!--
* Enabled by default.
* The feature is well tested. Enabling the feature is considered safe.
* 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.
-->

* 默认禁用。
* 该特性已经经过良好测试。启用该特性是安全的。
* 尽管详细信息可能会更改，但不会放弃对整体特性的支持。
