我有一个 cloudformation 模板来启动带有安全组的新实例。创建堆栈时会询问一个参数，我们只能在模板中给出一种实例类型，但我需要选择 AMI 架构(如 ubuntu、windows、Linux )。请分享您的想法或提供示例模板以实现相同的目标。 我的模板 json 如下，取自 AWS 站点以供引用(从示例复制)

最佳答案
您可以做的是创建一个参数，提供一个可供选择的列表。
下面的示例允许您在特定区域内选择 3 种操作系统类型。我对 AMI 标识符进行了硬编码，因此如果 AWS 更改 AMI ID，该标识符可能会过时。该模板使用映射从参数中指定的值和运行模板的区域中选择正确的 AMI ID。您可以轻松地将其扩展到许多不同的区域或操作系统类型。

关于amazon-web-services - 有没有办法使用cloudformation模板中的参数显示所有公共(public)AMI？，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/48397691/
