AWS CloudFormer 堆栈创建失败（无法在指定的持续时间内接收到 1 个资源信号）

Question

我尝试使用 AWS CloudFormer 为现有资源创建模板，但是，CloudFormer 堆栈创建多次失败，原因不明。您可以在下面找到完整的日志，我尝试将选项中的超时增加到 100 分钟，但我得到了相同的结果：

Answer 1

CloudFormation 正在等待来自 CloudFormer WebServer 实例的通知，在 CloudFormer 模板中使用 CreationPolicy.

指定

安装 CloudFormer 应用程序的引导脚本在运行 /opt/aws/bin/cfn-signal 通知 CloudFormation 应用程序安装正确的最后一步或之前失败。

引导脚本记录到 /var/log/setup_cloudformer.log，因此您可以通过查看那里获得有关失败原因的更多信息。

要尝试调查，您可以在 EC2 实例页面上选择 Launch More Like This 操作来启动另一个 CloudFormer WebServer 实例。然后您可以提供密钥对并更新安全组以允许 SSH 访问以查看日志。

Answer 2

在参数中，指定用户名和密码。必须创建实例。

Answer 3

除了 Anush Arvind 的回答，您还必须注意不要在密码中包含特殊字符。

来自官方文档：

You can't leave the password blank, and you can't use special characters in the password (such as ; & ! " £ $ % ^ ( ) / ).
