AWS LoadBalancer 监听多个端口

Question

我有一些应用程序在 aws 中作为微服务运行。其中一些在端口 80 上运行，其中一些在端口 3000 上运行。我希望我的 ALB 侦听两个端口上的流量。然后我有一个ListenRules将流量引导到微服务。我想实现以下目标，

Resources:
  LoadBalancer:
    Type: AWS::ElasticLoadBalancingV2::LoadBalancer
    Properties:
      Name: !Ref EnvironmentName
      Subnets: !Ref Subnets
      SecurityGroups:
        - !Ref SecurityGroup
      Tags:
        - Key: Name
          Value: !Ref EnvironmentName

  LoadBalancerListener:
    Type: AWS::ElasticLoadBalancingV2::Listener
    Properties:
      LoadBalancerArn: !Ref LoadBalancer
      Port: [80,3000] # something like this
      Protocol: HTTP
      DefaultActions:
        - Type: forward
          TargetGroupArn: !Ref DefaultTargetGroup

Answer 1

应该对每个要打开的端口重复侦听器。例如：

Resources:
LoadBalancer:
  Type: AWS::ElasticLoadBalancingV2::LoadBalancer
  Properties:
    Name: !Ref EnvironmentName
    Subnets: !Ref Subnets
    SecurityGroups:
      - !Ref SecurityGroup
    Tags:
      - Key: Name
        Value: !Ref EnvironmentName

LoadBalancerListenerA:
  Type: AWS::ElasticLoadBalancingV2::Listener
  Properties:
    LoadBalancerArn: !Ref LoadBalancer
    Port: 80
    Protocol: HTTP
    DefaultActions:
      - Type: forward
        TargetGroupArn: !Ref TargetGroupForPort80

LoadBalancerListenerB:
  Type: AWS::ElasticLoadBalancingV2::Listener
  Properties:
    LoadBalancerArn: !Ref LoadBalancer
    Port: 3000
    Protocol: HTTP
    DefaultActions:
      - Type: forward
        TargetGroupArn: !Ref TargetGroupForPort3000

这也允许为每个端口灵活设置不同的协议（例如 HTTPS）或目标组。
