-->
打印可用于 `kubeadm upgrade` 的默认升级配置。

<!--
### Synopsis

This command prints objects such as the default upgrade configuration that is used for 'kubeadm upgrade'.

Note that sensitive values like the Bootstrap Token fields are replaced with placeholder values like "abcdef.0123456789abcdef" in order to pass validation but
not perform the real computation for creating a token.
-->
### 概要

此命令打印 `kubeadm upgrade` 所用的默认升级配置等这类对象。

请注意，诸如启动引导令牌（Bootstrap Token）字段这类敏感值已替换为 "abcdef.0123456789abcdef"
这类占位符值用来通过合法性检查，但不执行创建令牌的实际计算。

```
kubeadm config print upgrade-defaults [flags]
```
