amazon-web-services - 我在 CloudFormation 中遇到多个安全组的问题

Question

我正在尝试选择两个安全组，一个是来自参数的安全组，另一个是新的安全组。

但出现以下错误。我该如何解决这个问题？

Error : Unsolved Resource dependence [Securitygroup !Ref Lpsecurity] in the resource block of the template.

Answer 1

列表中的每个元素之前应有破折号。

这是来自您的其他 I have a problem in cloud formation. Error when using Fn::Join with a parameter 的建议代码问题:

      SecurityGroupIds:
        - !GetAtt Securitygroup.GroupId
        - !GetAtt Lpsecurity.GroupId

或者，您可以使用:

      SecurityGroupIds:
          - !Ref Securitygroup
          - !Ref Lpsecurity
