validation - 调试 CloudFormation 验证问题

Question

我正在使用 linter 并且我的模板显示有效，但我的部署失败并出现“AWS::ElasticLoadBalancingV2::ListenerRule 验证异常”。 Cloud Formation 控制台中似乎没有任何地方可以进一步深入了解此异常。如何确定我的部署无效的原因？

错误

事件中的“状态原因”。

Resource handler returned message: "Invalid request provided: AWS::ElasticLoadBalancingV2::ListenerRule Validation exception" (RequestToken: 16bd4239-0d41-b16f-2963-b0a774009dfd, HandlerErrorCode: InvalidRequest)

Answer 1

尝试从 Conditions 键中删除 PathConfigPattern:

HttpsListenerRule:
  Type: AWS::ElasticLoadBalancingV2::ListenerRule
  Properties:
    Actions:
      - Type: "forward"
        ForwardConfig:
          TargetGroupStickinessConfig:
            Enabled: false
          TargetGroups:
            - TargetGroupArn: !FindInMap [ EnvMap, !Ref Env, LoadBalancerRouteTargetArn ]
              Weight: 1
        TargetGroupArn: !FindInMap [ EnvMap, !Ref Env, LoadBalancerRouteTargetArn ]
        Order: 1
    Conditions:
      - Field: path-pattern
        Values:
          - "/*"
    ListenerArn: !Ref HttpsListener
    Priority: 50000

此外，请确保您的 EnvMap map 如下所示:

Parameters:
  Env:
    Type: String
    Default: sandbox

Mappings:
  EnvMap:
    sandbox:
      LoadBalancerRouteTargetArn: "arn:aws:elasticloadbalancing:eu-west-1:111111111111:targetgroup/my-tg-1/222222222222"
    prod:
      LoadBalancerRouteTargetArn: "arn:aws:elasticloadbalancing:eu-west-1:333333333333:targetgroup/my-tg-2/444444444444"
