无法使用 AWS CloudFormation 将 EBS 驱动器安装到 Ubuntu 盒(UserData 不起作用)

无法使用 AWS CloudFormation 将 EBS 驱动器安装到 Ubuntu 盒(UserData 不起作用)

我有一个可以正常工作的 CloudFormation 模板,它创建了一个 AWS 实例 2 个 EBS 卷。这些卷可通过 lsblk 在机器上看到。我只是在格式化和安装它们时遇到了麻烦。就好像 UserData 脚本根本没有运行一样。

这是一台 Ubuntu 14.04 机器。你知道我可能做错了什么吗?

编辑:添加完整模板以供参考

答案就是——EBS 需要完全连接。
