The [Dynamic Kubelet Configuration](https://github.com/kubernetes/enhancements/tree/master/keps/sig-node/281-dynamic-kubelet-configuration)
|
||
feature is deprecated in 1.22 and removed in 1.24.

Please switch to alternative means distributing configuration to the Nodes of your cluster.

[动态 kubelet 配置](https://github.com/kubernetes/enhancements/tree/master/keps/sig-node/281-dynamic-kubelet-configuration)
|
||
功能在 Kubernetes 1.22 版本弃用，并在 1.24 版本中移除。
|
||
请选择其他方法将配置分发到集群中的节点。

|

[Dynamic Kubelet Configuration](https://github.com/kubernetes/enhancements/issues/281)
|

allowed you to change the configuration of each

{{< glossary_tooltip text="kubelet" term_id="kubelet" >}} in a running kubernetes cluster,
|
||
by deploying a {{< glossary_tooltip text="kubelet" text="ConfigMap" term_id="configmap" >}} and configuring

each {{< glossary_tooltip term_id="node" >}} to use it.

|

[动态 kubelet 配置](https://github.com/kubernetes/enhancements/issues/281)
|
||
允许你通过部署并配置{{< glossary_tooltip text="节点" term_id="node" >}}使用的
|
||
{{< glossary_tooltip text="ConfigMap" term_id="configmap" >}}，
|
||
达到更改正在运行的 Kubernetes 集群的 {{< glossary_tooltip text="kubelet" term_id="kubelet" >}}

配置的目的。

<!--
|

Please find documentation on this feature in [earlier versions of documentation](https://v1-23.docs.kubernetes.io/docs/tasks/administer-cluster/reconfigure-kubelet/).
|
||
-->
|
||
请在[早期版本的文档](https://v1-23.docs.kubernetes.io/zh-cn/docs/tasks/administer-cluster/reconfigure-kubelet/)中寻找有关此功能的文档。

|
||
## Migrating from using Dynamic Kubelet Configuration
|
||
|
||
There is no recommended replacement for this feature that works generically
|
||
across various Kubernetes distributions. If you are using managed Kubernetes
|
||
version, please consult with the vendor hosting Kubernetes for the best
|
||
practices for customizing your Kubernetes. If you are using `kubeadm`, refer to
|
||
[Configuring each kubelet in your cluster using kubeadm](/docs/setup/production-environment/tools/kubeadm/kubelet-integration/).
|
||
-->
|
||
## 不再使用动态 Kubelet 配置
|
||
|
||
这里没有跨不同的 Kubernetes 发行版替换这个功能的建议方法。
|
||
如果你使用托管 Kubernetes 版本，
|
||
请咨询托管 Kubernetes 的供应商，以获得自定义 Kubernetes 的最佳实践。
|
||
如果你使用的是 `kubeadm`，
|
||
请参考[使用 kubeadm 配置集群中的各个 kubelet](/zh-cn/docs/setup/production-environment/tools/kubeadm/kubelet-integration/)。
|
||
|
||
<!--
|
||
In order to migrate off the Dynamic Kubelet Configuration feature, the
|
||
alternative mechanism should be used to distribute kubelet configuration files.
|
||
In order to apply configuration, config file must be updated and kubelet restarted.
|
||
See the [Set Kubelet parameters via a config file](/docs/tasks/administer-cluster/kubelet-config-file/)
|
||
for information.
|
||
-->
|
||
为了停止使用动态 Kubelet 配置功能，
|
||
应该使用替代机制分发 kubelet 配置文件。
|
||
为了使配置生效，必须更新配置文件并重新启动 kubelet。
|
||
请参考[通过配置文件设置 Kubelet 参数](/zh-cn/docs/tasks/administer-cluster/kubelet-config-file/)。
|
||
|
||
<!--
|
||
Please note, the `DynamicKubeletConfig` feature gate cannot be set on a kubelet
|
||
starting v1.24 as it has no effect. However, the feature gate is not removed
|
||
from the API server or the controller manager before v1.26. This is designed for
|
||
the control plane to support nodes with older versions of kubelets and for
|
||
satisfying the [Kubernetes version skew policy](/releases/version-skew-policy/).
|
||
-->
|
||
请注意，从 v1.24 开始 `DynamicKubeletConfig` 特性门控无法在 kubelet 上设置，
|
||
因为不会生效。在 v1.26 之前 API 服务器和控制器管理器不会移除该特性门控。
|
||
这是专为控制面支持有旧版本 kubelet 的节点以及满足
|
||
[Kubernetes 版本偏差策略](/zh-cn/releases/version-skew-policy/)。
