title: Set Kubelet parameters via a config file

<!-- overview -->
|
||
|
||
<!--
|
||
A subset of the Kubelet's configuration parameters may be
|
||
set via an on-disk config file, as a substitute for command-line flags.
|
||
--->
|
||
通过保存在硬盘的配置文件设置 kubelet 的部分配置参数，这可以作为命令行参数的替代。
|
||
|
||
<!--
|
||
Providing parameters via a config file is the recommended approach because
|
||
it simplifies node deployment and configuration management.
|
||
--->
|
||
建议通过配置文件的方式提供参数，因为这样可以简化节点部署和配置管理。
|
||
|
||
<!-- steps -->
|
||
|
||
<!--
|
||
## Create the config file
|
||
|
||
The subset of the Kubelet's configuration that can be configured via a file
|
||
is defined by the
|
||
[`KubeletConfiguration`](/docs/reference/config-api/kubelet-config.v1beta1/)
|
||
struct.
|
||
-->
|
||
## 创建配置文件
|
||
|
||
[`KubeletConfiguration`](/zh/docs/reference/config-api/kubelet-config.v1beta1/) 结构体定义了可以通过文件配置的 Kubelet 配置子集，
|
||
|
||
<!--
|
||
The configuration file must be a JSON or YAML representation of the parameters
|
||
in this struct. Make sure the Kubelet has read permissions on the file.
|
||
|
||
Here is an example of what this file might look like:
|
||
-->
|
||
配置文件必须是这个结构体中参数的 JSON 或 YAML 表现形式。
|
||
确保 kubelet 可以读取该文件。
|
||
|
||
下面是一个 Kubelet 配置文件示例：
|
||
```
|
||
apiVersion: kubelet.config.k8s.io/v1beta1
|
||
kind: KubeletConfiguration
|
||
address: "192.168.0.8",
|
||
port: 20250,
|
||
serializeImagePulls: false,
|
||
evictionHard:
|
||
memory.available: "200Mi"
|
||
```
|
||
|
||
|
||
<!--
|
||
In the example, the Kubelet is configured to serve on IP address 192.168.0.8 and port 20250, pull images in parallel,
|
||
and evict Pods when available memory drops below 200Mi.
|
||
All other Kubelet configuration values are left at their built-in defaults, unless overridden
|
||
by flags. Command line flags which target the same value as a config file will override that value.
|
||
-->
|
||
在这个示例中, Kubelet 被设置为在地址 192.168.0.8 端口 20250 上提供服务，以并行方式拖拽镜像，
|
||
当可用内存低于 200Mi 时, kubelet 将会开始驱逐 Pods。
|
||
没有声明的其余配置项都将使用默认值，除非使用命令行参数来重载。
|
||
命令行中的参数将会覆盖配置文件中的对应值。
|
||
|
||
<!--
|
||
## Start a Kubelet process configured via the config file
|
||
|
||
{{< note >}}
|
||
If you use kubeadm to initialize your cluster, use the kubelet-config while creating your cluster with `kubeadmin init`.
|
||
See [configuring kubelet using kubeadm](/docs/setup/production-environment/tools/kubeadm/kubelet-integration/) for details.
|
||
{{< /note >}}
|
||
|
||
Start the Kubelet with the `--config` flag set to the path of the Kubelet's config file.
|
||
The Kubelet will then load its config from this file.
|
||
--->
|
||
|
||
## 启动通过配置文件配置的 Kubelet 进程
|
||
|
||
{{< note >}}
|
||
如果你使用 kubeadm 初始化你的集群，在使用 `kubeadmin init` 创建你的集群的时候请使用 kubelet-config。
|
||
更多细节请阅读[使用 kubeadm 配置 kubelet](/zh/docs/setup/production-environment/tools/kubeadm/kubelet-integration/)
|
||
{{< /note >}}
|
||
|
||
启动 Kubelet 需要将 `--config` 参数设置为 Kubelet 配置文件的路径。Kubelet 将从此文件加载其配置。
|
||
|
||
<!--
|
||
Note that command line flags which target the same value as a config file will override that value.
|
||
This helps ensure backwards compatibility with the command-line API.
|
||
-->
|
||
请注意，命令行参数与配置文件有相同的值时，就会覆盖配置文件中的该值。
|
||
这有助于确保命令行 API 的向后兼容性。
|
||
|
||
<!--
|
||
Note that relative file paths in the Kubelet config file are resolved relative to the
|
||
location of the Kubelet config file, whereas relative paths in command line flags are resolved
|
||
relative to the Kubelet's current working directory.
|
||
-->
|
||
请注意，kubelet 配置文件中的相对文件路径是相对于 kubelet 配置文件的位置解析的，
|
||
而命令行参数中的相对路径是相对于 kubelet 的当前工作目录解析的。
|
||
|
||
<!--
|
||
Note that some default values differ between command-line flags and the Kubelet config file.
|
||
If `--config` is provided and the values are not specified via the command line, the
|
||
defaults for the `KubeletConfiguration` version apply.
|
||
In the above example, this version is `kubelet.config.k8s.io/v1beta1`.
|
||
--->
|
||
请注意，命令行参数和 Kubelet 配置文件的某些默认值不同。
|
||
如果设置了 `--config`，并且没有通过命令行指定值，则 `KubeletConfiguration`
|
||
版本的默认值生效。在上面的例子中，version 是 `kubelet.config.k8s.io/v1beta1`。
