我想简单地使用亚马逊的Cloud Formation工具来创建带有Ubuntu 16.04映像的EC2实例。
这应该很简单，只是图像ID似乎根据机器的区域和体系结构类型而有很大差异。
例如，这是Lamp示例中提供的示例代码的一小部分，用于创建运行Amazon操作系统的EC2实例：

如何为Ubuntu 16.04做类似的事情？ 有更简单的方法吗？
答案 0 :(得分：1)
在Cloudformation中，您可以通过Mappings进行查找。因此，要创建可在任何区域中运行的脚本，您需要在区域和AMI id之间创建映射。
您可以从list of cloud images获取AMI列表。
如果您不需要能够选择不同类型的AMI（每个区域有16种不同的AMI，列出的16.04），您只需在地图中包含所需类型，或创建多个地图如果那就是你需要的价值。
