TaskDefinition - 遇到不受支持的属性名称 - 环境

Question

运行声明一些环境变量的 CloudFormation 脚本时，CloudFormation 会引发以下错误：

CREATE_FAILED   AWS::ECS::TaskDefinition    ECSTaskDefinition   Encountered unsupported property Name

这与 CloudFormation 模板中的以下资源有关

"ECSTaskDefinition": {
    "Type": "AWS::ECS::TaskDefinition",
    "Properties": {
        "Cpu": "256",
        "ExecutionRoleArn": {
            "Fn::GetAtt": [
                "ECSTaskRole",
                "Arn"
            ]
        },
        "Family": {
            "Ref": "AWS::StackName"
        },
        "Memory": "500",
        "NetworkMode": "awsvpc",
        "RequiresCompatibilities": [
            "FARGATE"
        ],
        "ContainerDefinitions": [
            {
                "Environment": [
                    {
                        "Name": "cloudsearch:search_endpoint",
                        "Value": {
                            "Ref": "CloudSearchDomainServiceUrl"
                        }
                    }
                ],
                "Essential": true,
                "Image": {
                    "Ref": "ContainerImage"
                }
            }
        ]
    }
}

我不确定上述有什么问题，因为从文档中正确声明了 Environment 块 -https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/aws-properties-ecs-taskdefinition-containerdefinitions-environment.html

任何帮助将不胜感激。

 ECSAppTask:

                      ContainerPath: /default/logs
                      SourceVolume:  !FindInMap
                                        - ECSEnvironmentDetails
                                        - !Ref EnvironmentTier
                                        - AppVolumeName
        Volumes:
            - 
              Host:
                SourcePath: !FindInMap
                                 - ECSEnvironmentDetails
                                 - !Ref EnvironmentTier
                                 - AppVolumeSourcePath
              Name: !FindInMap
                       - ECSEnvironmentDetails
                       - !Ref EnvironmentTier
                       - AppVolumeName 

这是我定义任务定义的 yaml 文件，它可以工作。一开始我遇到了同样的问题“TaskDefinition - Encountered unsupported property Name - Environment”，然后我意识到我在环境键值列表中使用了所有小写字母， 所以我改变了yaml中的环境：

       Environment:
                    - name: CONFIGURE_MODE
                      value: config_mode
                    - name: ENVIRONMENT
                      value: env
                    - name: ENVTYPE
                      value: env_type
                    - name: LICENSE
                      value: accept

到

            Environment:
                    - Name: CONFIGURE_MODE
                      Value: config_mode
                    - Name: ENVIRONMENT
                      Value: env
                    - Name: ENVTYPE
                      Value: env_type
                    - Name: LICENSE
                      Value: accept

并尝试更新或重新创建堆栈，均已成功完成。

想知道问题是否与环境变量cloudsearch:search_endpoint 的实际名称有关，通常我们遵循 bash 变量约定来创建环境变量，尝试类似CLOUDSEARCH_SEARCH_ENDPOINT
