使用 AWS CloudFormation 服务,我尝试在 2 个 EC2 实例上创建 Application Elastic Load Balancer,但在创建侦听器 [AWS::ElasticLoadBalancingV2::Listener] 时出现错误,如下所示:

“AELB-ElasticLoadBa-XDTNTTXRZMC8' 必须采用 ARN 格式(服务:AmazonElasticLoadBalancingV2;状态代码:400;错误代码:ValidationError;请求 ID:9b18bb79-9e58-11e8-9b70-c9b2be714e80)”

我已经参考了 aws 代码模板并在下面添加了代码,我是否遗漏了什么?

ElasticLoadBalancer:

    HealthyThreshold: '3'
    UnhealthyThreshold: '5'

    'Fn::Join': 
      - '-'

  #HealthCheckPath: /service1

      - '-'
      - - Ref: 'AWS::StackName'
        - 'TargetGroupService2'

  Protocol: HTTP
  #HealthCheckPath: /service2
  Targets:

Listener:

您使用了错误的 cloudformation 资源。Type应用程序负载均衡器的AWS::ElasticLoadBalancingV2::LoadBalancer. 注意V2. 您正在使用的那个创建了一个经典的负载均衡器。

Ref您得到的错误是由于经典 LB 和应用程序 LB 之间函数的返回值不同。

当您指定:

LoadBalancerArn: !Ref ElasticLoadBalancer

Ref经典 LB 返回资源名称 (AELB-ElasticLoadBa-XDTNTTXRZMC8),而RefALB 返回资源 Arn,这是 V2 侦听器期望的LoadBalancerArn属性。

将具有逻辑名称的资源替换为具有此处ElasticLoadBalancer描述的适当属性的 V2 负载均衡器应该可以解决您的问题。
