amazon-web-services - AWS CloudFormation 模板“找不到启动配置名称”

Question

我在创建 AWS CloudFormation 模板时遇到了这个问题。我正在创建一个 AutoScaling 组并将 LaunchConfiguration 分配给它，但是当我运行模板时，我收到错误“找不到启动配置名称 - 名称为：WebServerASLaunchConfig 的启动配置不存在”。这是确切的代码片段

 "WebServerASLaunchConfig": {

            }
         },

                ],

                                    {

                                    },
                                    "VPC"
                                ]                                
                            ]
                        },
                        "PropagateAtLaunch": "True"
                    }
                ]
            }
        }

谢谢您的帮助

要引用任何参数或资源，请使用Ref。

替换"LaunchConfigurationName": "WebServerASLaunchConfig", 为：

"LaunchConfigurationName": { "Ref": "WebServerASLaunchConfig" }
