Cloud Init 在 EC2 中的 CentOS 7 上安装软件包失败

Question

我在用户数据中的 EC2 实例上定义了一个云配置文件。许多 parts/actions 被服务器正确地运行，但软件包安装似乎总是失败：

#cloud-config
package-update: true
package-upgrade: true
# ...
packages:
 - puppet3
 - lvm2
 - btrfs-progs
# ...

我在日志中看到以下内容：

当我实际上运行命令 yum -t -y install puppet3 lvm2 btrfs-progs 时，它只是运行没问题，但 Cloud Init 无法自行运行它。

我是不是做错了什么？

显然，图像的更高版本修复了一个错误。如果这发生在你身上，它可能是 Cloud-Init 或你的服务器实现中的一个合法错误。软件包升级可能会解决问题，图像更新也会在全局范围内解决。
