ターゲットグループには、関連付けられたロードバランサーがありません

クラウドフォーメーションスクリプトからECSサービスを作成したい。サービスはApplication Load Balancerで外部に公開する必要があります

Elastic Load Balancer、リスナー、ListnerRuleを作成しました

cloudformationでスクリプトを実行すると、エラーがスローされます

あなたが持っている究極の問題はAWS::ECS::Serviceターゲットグループがロードバランサーに追加される前に、ターゲットグループに接続しようとしています。その修正は非常に簡単です。

 Service:
    Type: AWS::ECS::Service
    DependsOn: Listener       # Line Added
    Properties:
      Cluster: !Ref ECSCluster
      Role: 'ecserviceRole'
      DesiredCount: '2'
      TaskDefinition: !Ref TaskDefinition
      LoadBalancers:
        - TargetGroupArn: !Ref TargetGroup
          ContainerPort: 80
          ContainerName: "product-service"

そうは言っても、多くのエラーがあるため、LoadBalancer定義も更新する必要があります。そのはず：

  LoadBalancer:
    Type: AWS::ElasticLoadBalancingV2::LoadBalancer
    Properties:
      Name: 'my-load-balancer'
      Subnets:
        - !Ref PubSubnetAz1
        - !Ref PubSubnetAz2
      SecurityGroups: 
        - !Ref LoadBalancerSecurityGroup
