AWS LoadBalancer可以监听多个端口

本文介绍了AWS LoadBalancer可以监听多个端口的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！

问题描述

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，而某些在端口3000上运行.我希望我的ALB监听两个端口上的流量.然后，我有一个ListenRules将流量定向到微服务.我想实现以下目标，

I have a few applications running as Microservices in aws. Some of them are running on port 80 and some of them are running on port 3000. I want my ALB to listen to traffic on both ports. Then I have a ListenRules to direct the traffic to Microservices. I want to achieve something like below,

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

推荐答案

应该对要打开的每个端口重复侦听器.例如:

The Listener should be repeated with each port that is to be opened. For example:

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

这还使您可以灵活地为每个端口设置不同的协议(例如HTTPS)或目标组.

This also allows the flexibility of setting different protocols (e.g. HTTPS) or target groups for each port.
