尝试使用cloudformation创建ECS服务(在Fargate上),但出现错误:
ARN中的服务无效(服务:AmazonECS;状态代码:400;错误 代码:InvalidParameterException;请求ID:xxx)。
根据错误消息,似乎有些ARN是错误的,但是我没有找到原因,我检查了IAM角色的ARN及其确定。另一个ARN与!Ref函数一起传递(因此不会出现拼写错误)
除了“服务”资源(ECS服务)以外,所有资源(包括所有其他嵌套模板,vpc,集群,alb等)均已创建。
下面是使用的模板(嵌套模板)。所有参数均正确(从根模板传递)。参数TaskExecutionRole和ServiceRole是ECS向导创建的IAM角色的ARN:

我为此花了几个小时而无法解决,我在文档中回顾了很多,但如果有人知道如何提供帮助,则什么也没有。
谢谢!
答案 0 :(得分:2)
错误信息令人困惑,因为它没有说明哪个参数是错误的。 Amazon API 需要多个参数中的资源 ARN,包括 Cluster
、TaskDefinition
和 TargetGroup
。当这些参数之一错误时会发生错误。请仔细检查这些参数并确保它们是有效的 ARN。
我遇到了完全相同的错误,就我而言,我犯了一个错误并提供了错误的 Cluster
值。
我在这里发布答案是因为这是此错误消息的第一个搜索结果,但没有答案。
