amazon-web-services - Cloudformation 模板中的循环依赖

Question

我已经在这个问题上思考了几天了。我收到 Circular dependency between resources: [ApiEcsEventsRuleProduct] 的错误我在 ApiEcsTaskDefinition 中也有循环依赖错误如果我删除 ApiEcsEventsRuleProduct共。该错误不会使调试变得明显。任何帮助将不胜感激。

Answer 1

这就是问题:

DependsOn:
  - ApiEcsEventsRuleProduct

ApiEcsEventsRuleProduct 资源不能拥有对其自身的引用。
