当我部署模板时，它失败了。当我打印事件日志时。据说创建 DBSecurityGroup 失败。我的模板有什么问题以及如何修复它？

Answer 1

模板中的最后一行应该是

SourceSecurityGroupId:!GetAtt WebServerSecurityGroup.GroupId .

我还注意到在 AWS::EC2::Subnet 中，CidrBlock 属性应该是

CidrBlock: !Select [ 0, !Cidr [ !GetAtt Vpc.CidrBlock, 12, 8 ] ]

和

CidrBlock: !Select [ 2, !Cidr [ !GetAtt Vpc.CidrBlock, 12, 8 ] ]
