不允许使用无关密钥[HealthCheck]

Question

我被这个奇怪的错误困住了。我正在使用CloudFormation脚本部署一个ECS (Fargate)，它工作并成功地部署了任务。但是，当设置HealthCheck属性时，Cloudformation

Resource handler returned message: "Model validation failed (#: extraneous key [HealthCheck] is not permitted)" (RequestToken: xxxxxxx-xxx-xxxx-xxxx-xxxxxxxxxxxx, HandlerErrorCode: InvalidRequest)

我的任务定义是：

  TaskDefinition:
    Type: AWS::ECS::TaskDefinition
    Properties:
      Family: !Sub ${ServiceName}-${EnvironmentName}
      Cpu: !Ref 'ContainerCpu'
      Memory: !Ref 'ContainerMemory'
      NetworkMode: awsvpc
      RequiresCompatibilities:
        - FARGATE

          - !Ref 'Role'

      ContainerDefinitions:
        - Name: !Ref 'ServiceName'

          PortMappings:
            - ContainerPort: !Ref 'ContainerPort'
          LogConfiguration:
            LogDriver: 'awslogs'
            Options:
              awslogs-group: !Sub ${ServiceName}-service-${EnvironmentName}
              awslogs-region: !Ref 'AWS::Region'
              awslogs-stream-prefix: !Ref 'ServiceName'
          Environment:
            - <some other environment that work ok>

Answer 1

HealthCheck是AWS::ECS::TaskDefinition.ContainerDefinition的子属性，而不是AWS::ECS::TaskDefinition的顶级属性。
