How to create multiple cloudformation stacks where a single parameter changes?
问题
我想将城市列表作为参数输入到 SAM 模板中。例如：伦敦、纽约、迪拜。列表可能包含大量城市，比如说 50 个。
使用这个城市列表，我想为每个城市创建一个相应的日志组。例如：
- /aws/ecs/迪拜
- /aws/ecs/伦敦
- /aws/ecs/纽约
我该如何实现这个？

Using this list of cities, I want to create a log group pertaining to each city. For example:
- /aws/ecs/Dubai
- /aws/ecs/London
- /aws/ecs/New York
How can I achieve this?

你可以在Cloudformation中使用Count Macro。
AWSTemplateFormatVersion: "2010-09-09"
Transform: Count
Resources:
Type: AWS::Logs::LogGroup
Properties:
LogGroupName: /aws/ecs/%s
Count: ['Dubai','London','NewYork']
