Amazon web services Cfn林特：不动产；ExecutionRoleArn“；在Resources/TaskDefinition/Properties/ExecutionRoleArn/Ref中没有对资源的有效引用

我正在构建一个cloudformation模板，以便在AWS上运行ECS群集和ECS任务

此外，我正在使用带有插件Cfn Lint的Atom文本编辑器

如图所示，我在Atom文本编辑器中面临以下cfn linter验证问题

共享一些代码片段

      ExecutionRoleArn: !Ref ExecutionRole

最后一行代码

ExecutionRoleArn:！Ref ExecutionRole

给出了Cfn Lint Atom插件中的错误

尽管模板成功运行并创建部署。

要获取

Arn

，您必须使用intristic功能：

ExecutionRoleArn: !GetAtt ExecutionRole.Arn
