The init configuration is used for starting the kubelet on this specific node, providing an alternative for the kubelet drop-in file;
such configuration will be replaced by the kubelet base configuration as described in following steps.

初始化配置用于在这个特定节点上启动 kubelet，从而为 kubelet 插件文件提供了
一种替代方法。如以下步骤中所述，这种配置将由 kubelet 基本配置所替代。

了解更多信息。

1. To make dynamic kubelet configuration work, flag `--dynamic-config-dir=/var/lib/kubelet/config/dynamic` should be specified
in `/etc/systemd/system/kubelet.service.d/10-kubeadm.conf`
1. The kubelet configuration can be changed by passing a `KubeletConfiguration` object to `kubeadm init` or `kubeadm join` by using
a configuration file `--config some-file.yaml`. The `KubeletConfiguration` object can be separated from other objects such
as `InitConfiguration` using the `---` separator. For more details have a look at the `kubeadm config print-default` command.

1. 要使动态 kubelet 配置生效，应在 `/etc/systemd/system/kubelet.service.d/10-kubeadm.conf`
中指定 `--dynamic-config-dir=/var/lib/kubelet/config/dynamic` 标志。
1. 通过使用配置文件 `--config some-file.yaml` 将 `KubeletConfiguration` 对象传递给
`kubeadm init` 或 `kubeadm join` 来更改 kubelet 配置。
可以使用 `---` 分隔符将 `KubeletConfiguration` 对象与其他对象（例如 `InitConfiguration`）
分开。更多的详细信息，请查看 `kubeadm config print-default` 命令。
