Amazon web services 如何在CloudInformation中将目标添加到网络负载平衡器

我有一些关于网络负载均衡器的云信息

  PrivateNetworkLoadBalancerSG:
    Type: AWS::EC2::SecurityGroup
    Properties:
      GroupDescription: Access to the internal network load balancer
      VpcId: !Ref 'VPC'
  PrivateNetworkLoadBalancerIngressFromECS:
    Type: AWS::EC2::SecurityGroupIngress
    Properties:
      Description: Only accept traffic from a container in the container host security group
      GroupId: !Ref 'PrivateNetworkLoadBalancerSG'
      IpProtocol: -1
      SourceSecurityGroupId: !Ref 'EcsHostSecurityGroup'
  PrivateNetworkLoadBalancer:
    Type: AWS::ElasticLoadBalancingV2::LoadBalancer
    Properties:
      Type: network
      Scheme: internal
      Subnets:
        - !Ref PrivateSubnetOne
        - !Ref PrivateSubnetTwo
  DummyTargetGroupPrivateNetwork:
    Type: AWS::ElasticLoadBalancingV2::TargetGroup
    Properties:
      Name: !Join ['-', [!Ref 'AWS::StackName', 'drop-3']]
      Port: 6379
      Protocol: TCP
      # UnhealthyThresholdCount: 2
      VpcId: !Ref 'VPC'

还有一些用于在ECS中设置Redis docker容器

  RedisService:
    Type: AWS::ECS::Service
    Properties:
      Cluster: !ImportValue "privatevpc:ClusterName"
      DesiredCount: 1
      TaskDefinition: !Ref RedisTaskDefinition

  RedisTaskDefinition:
    Type: AWS::ECS::TaskDefinition
    Properties:
      Family: redis
      ContainerDefinitions:
        - Name: redis
          Essential: true
          Image: "redis:latest"
          Memory: 512
          PortMappings:
            - ContainerPort: 6379
              HostPort: 6379
          LogConfiguration:
            LogDriver: awslogs
            Options:
              awslogs-group: !Ref CloudWatchLogsGroup
              awslogs-region: !Ref AWS::Region

  RedisTargetGroup:
    Type: AWS::ElasticLoadBalancingV2::TargetGroup
    Properties:
      VpcId: !ImportValue "privatevpc:VPCId"
      Port: 6379
      Protocol: TCP
      HealthCheckProtocol: TCP

  RedisLoadBalancerListener:
    Type: AWS::ElasticLoadBalancingV2::Listener
    Properties:
      DefaultActions:
      - Type: forward
        TargetGroupArn: !Ref RedisTargetGroup
      LoadBalancerArn: !ImportValue "privatevpc:PrivateNetworkLoadBalancer"
      Port: 6379
      Protocol: TCP

但是我必须手动添加我的RedisService部署到的EC2实例，作为通过AWS web控制台的RedisTargetGroup的目标。你知道如何让CloudFormation为我做到这一点吗？

我想你需要将

LoadBalancers

属性添加到

RedisService

。ECS应自动将正确的EC2实例添加到指定的目标组中

例如：

  RedisService:
    Type: AWS::ECS::Service
    Properties:
      Cluster: !ImportValue "privatevpc:ClusterName"
      DesiredCount: 1
      TaskDefinition: !Ref RedisTaskDefinition
      LoadBalancers:
        - ContainerName: redis
          ContainerPort: 6379
          TargetGroupArn: !Ref RedisTargetGroup

我认为可以通过一些示例来指导您，在这些示例中，他们创建了一些云信息资源，如您需要的资源：这就是我的起点。您需要添加自动缩放。你试过了吗？
