为了保护我们的API,我正在尝试使用RateBasedRule部署WAFRegional。API网关位于SAM模板中,其中我还有一个嵌套堆栈,用于存放WAFRegional配置的子模板。下面提供了WAFRegional配置的子模板。在ExecuteChangeSet阶段将发生以下情况:
CamerasIpSet已创建
创建了CamerasRateRule
WAFCamerasWebACL CREATE_FAILED:引用的项目不存在。(服务:AWSWAFRegional;状态代码:400;错误代码:WAFNonexistentItemException
我发现大约2个月前的以下帖子,其中有人在使用Serverless时遇到相同的问题:https : //forum.serverless.com/t/dependon-api-gateway-deployment/7792
我在这里错过了什么?

我终于在AWS客户服务的帮助下解决了这个问题。当处理AWS :: WAFRegional :: RateBasedRule时,这是CloudFormation的限制。
尽管CloudFormation支持创建基于WAF区域费率的规则,但当前不支持将它们与Web ACL关联。如果您观察下面的链接[1],您将意识到:“要将通过CloudFormation创建的基于费率的规则添加到Web ACL,请使用AWS WAF控制台,API或命令行界面(CLI)。”
[1] AWS :: WAFRegional :: RateBasedRule:https ://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/aws-resource-wafregional-ratebasedrule.html
我使用Cloudformation模板生成了WebACL,RateBasedRule以及WebACL与我的APIGW的关联。现在,在我们的CI / CD管道中使用CodeBuild,我现在使用CLI命令将RateBasedRule添加到WebACL aws waf-regional update-web-acl。
