### 概要

<!--
Generate the private key for signing service account tokens along with its public key, and save them into sa.key and sa.pub files.
-->
生成用来签署服务账号令牌的私钥及其公钥，并将其保存到 `sa.key` 和
`sa.pub` 文件中。

<!--
If both files already exist, kubeadm skips the generation step and existing files will be used.

如果两个文件都已存在，则 kubeadm 会跳过生成步骤，而将使用现有文件。

```
