amazon-web-services - 云信息 : ELB listener rule creation fails with "Invalid request provided"

Question

我正在尝试建立一个小型 Cloudformation 堆栈，其中包含应用程序负载均衡器、目标组和 ECS 服务。但是，堆栈无法创建 WidgetsServiceLbListenerRule资源出现以下错误:

"Invalid request provided: AWS::ElasticLoadBalancingV2::ListenerRule Validation exception" (RequestToken: 98057bbb-ad4f-5f09-3e89-cc6b645c6e7f, HandlerErrorCode: InvalidRequest)

为什么监听器规则创建失败？

这是相关的堆栈代码:

Resources:

  # The load balancer
  Lb:
    Type: AWS::ElasticLoadBalancingV2::LoadBalancer
    Properties:
      Name: !Join ['', [!Ref Env, '-rest-api-lb-rev', !Ref Rev]]
      Scheme: internet-facing
      SecurityGroups:
        - !Ref LbSg
      Subnets:
        - Fn::ImportValue: !Sub "${VpcStackName}-PubSubnet1Id"
        - Fn::ImportValue: !Sub "${VpcStackName}-PubSubnet2Id"
        - Fn::ImportValue: !Sub "${VpcStackName}-PubSubnet3Id"
      Type: application
  LbListener:
    Type: AWS::ElasticLoadBalancingV2::Listener
    Properties:
      DefaultActions:
        - Type: fixed-response
          FixedResponseConfig:
            ContentType: text/plain
            MessageBody: The specified route doesn't exist
            StatusCode: 404
      LoadBalancerArn: !Ref Lb
      Port: 80
      Protocol: HTTP

  # Widgets service
  WidgetsServiceLbTargetGroup:
    Type: AWS::ElasticLoadBalancingV2::TargetGroup
    Properties:
      HealthCheckPath: /actuator/health
      Name: !Join ['', [!Ref Env, '-widgets-rev', !Ref Rev]]
      Port: 80
      Protocol: HTTP
      VpcId:
        Fn::ImportValue: !Sub "${VpcStackName}-VpcId"

  # THIS ONE FAILS TO CREATE
  WidgetsServiceLbListenerRule:
    Type: AWS::ElasticLoadBalancingV2::ListenerRule
    Properties:
      Actions:
        - Type: forward
          TargetGroupArn: !Ref WidgetsServiceLbTargetGroup
      Conditions:
        - Field: path-pattern
          Values:
            - '/widgets*'
      ListenerArn: Ref !LbListener
      Priority: 1
 
<ECS service and other assets omitted for brevity>

更多信息

• 我们的 AWS 账户中有多个现有堆栈，它们使用几乎完全相同的代码。这些和这个之间没有任何有意义的差异，而且它们工作得很好。
• 我创建了一个没有 WidgetsServiceLbListenerRule 的堆栈然后尝试将其作为更改集添加回来。这也产生了同样的错误。
• 我能够使用以下 AWS CLI 命令成功创建规则:aws --profile clexp elbv2 create-rule --listener-arn <arn> --priority 1 --conditions file://conditions.json --actions file://actions.json

条件.json:

[{"Type": "forward","TargetGroupArn": "<arn>"}]

actions.json:

[{"Field": "path-pattern","Values": ["/widgets*"]}]

非常感谢任何帮助。

而不是:

ListenerArn: Ref !LbListener

应该是:

ListenerArn: !Ref LbListener
