Python 指定aws ECS/Fargate容器依赖项失败

我使用aws cdk Python语言获得了以下代码，但部署失败，出现redis_容器不可用错误，我做错了什么，我希望redis容器先启动，然后再启动其余的。也许我对容器依赖性的理解不正确

        ecs_redis_task = ecs.FargateTaskDefinition(self,
        id = 'redis',
        cpu=512,
        memory_limit_mib =1024
        )

        redis_container = ecs_redis_task.add_container(id = 'redis_container',
        image = img_.from_ecr_repository(repository=repo_, tag='redis_5.0.5')
              )

        redis_container.add_port_mappings({
            'containerPort' : 6379
        })

        redis_dependency = ecs.ContainerDependency(container = redis_container, condition = ecs.ContainerDependencyCondition.HEALTHY)

        ecs_webserver_task = ecs.FargateTaskDefinition(self,
        id = 'webserver',
        cpu=256,
        memory_limit_mib =512
        )

        webserver_container = ecs_webserver_task.add_container(id = 'webserver_container',
        image = img_.from_ecr_repository(repository=repo_, tag='airflow_1.10.9')
       )

        webserver_container.add_port_mappings({
            'containerPort' : 8080
        })

        webserver_container.add_container_dependencies(redis_dependency)

如果我删除依赖代码，它就可以部署了

错误：

12/24 | 2:46:51 PM | CREATE_FAILED        | AWS::ECS::TaskDefinition                    | webserver (webserverEE139216) Cannot depend on container + 'redis_container' because it does not exist (Service: AmazonECS; Status Code: 400; Error Code: ClientException; Request ID: 81828979-9e65-474e-ab0e-b163168d5613)

我刚刚尝试了这段代码，它在任务定义中添加依赖项后效果如预期，代码中唯一改变的是图像：

cdk合成后的云形成：

      "Type": "AWS::ECS::TaskDefinition",
      "Properties": {
        "ContainerDefinitions": [

            "DependsOn": [
              {
                "Condition": "HEALTHY",
                "ContainerName": "redis_container"
              }
            ],

              }
            ]
          }
        ],

确切的错误是什么添加了错误，它没有提供太多这是不允许的循环依赖项。@shariqmaws您能指出循环依赖项在哪里吗？感谢您的回答，我能够解决这个问题，看起来ecr.Repository.from_Repository_name没有返回正确的引用：arn看起来像arn:${Token[AWS:：Partition.3]}:ecr:${Token[AWS:：Region.4]}:${Token[AWS:：AccountId.0]}:Repository/afflow将其更改为ecr.Repository.from_Repository_arn现在引用工作正常。arn:aws:ecr:us-east-1:XXXXXXXXXX:repository/airflow
