amazon-web-services - 如何在 CloudFormation 中使用 ECS PlacementConstraints

Question

我尝试在使用 CloudFormation 的服务定义中使用 placementConstraints，但它不作为 AWS::ECS::Service 资源中的属性存在。有解决办法吗？

ECS服务:http://docs.aws.amazon.com/AmazonECS/latest/developerguide/service_definition_paramters.html

CloudFormation ECS 服务资源:http://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/aws-resource-ecs-service.html

在撰写本文时，

PlacementConstraint 作为 AWS::ECS::Service 的属性存在。引用自 AWS 文档:

PlacementConstraint is a property of the AWS::ECS::Service resource that specifies the placement constraints for the tasks in the service to associate with an Amazon EC2 Container Service (Amazon ECS) service.
