Packer: Packer 1.1.3 因“ResourceNotReady：超出等待尝试”而无法用于 AWS

我有一个在 AWS 上构建的 CentOS Packer，它适用于 1.1.2 版，但在 1.1.3 版上失败

用于构建镜像的模板（来源 AMI ID 取自 https://wiki.centos.org/Cloud/AWS）

_如你所见，我没有做任何复杂的事情，只是一个支持 Docker 的 CentOS 7 镜像。_

当使用版本 1.1.3 构建失败时，它会超时并显示以下错误：

==> amazon-ebs: Waiting for instance (i-xxxxxxxxxxxxxxxxx) to become ready...
==> amazon-ebs: Error waiting for instance (i-xxxxxxxxxxxxxxxxx) to become ready: ResourceNotReady: exceeded wait attempts

• 来自packer version Packer 版本
  1.1.2
  1.1.3
• 主机平台
  Ubuntu 14.04（但我认为这不重要）

如果我使用 v 1.1.2运行 about 模板，它工作正常。 （我用 1.10 和 1.1.1 进行了测试，这些也有效）

问候，
