amazon-web-services - 发现 CloudFormation ECS ContainerDefinitions 预期类型 : JSONArray,:字符串

Question

我尝试部署 CloudFormation 模板并收到以下错误:

(这是一个 YAML 文件)

资源处理程序返回消息:“模型验证失败(#/ContainerDefinitions:预期类型:JSONArray，找到:String)”(RequestToken:d23861e3-70c3-2777-96ce-18b46a118437，HandlerErrorCode:InvalidRequest)

我必须从下面的代码中删除一些值，但除此之外它的布局相同。

容器定义中的管道将在 yaml 中强制使用字符串。这就是问题所在。
