Serverless/Cloudformation 依赖于另一个资源存在的资源

Serverless/Cloudformation resource that depends on the existence of another resource

我正在尝试使用无服务器框架部署 Kinesis Firehose,它输出到 ElasticSearch 域。

由于 Firehose 在创建之前需要 ES 域已经存在,我 运行 陷入了这个错误:

An error occurred: MyFirehoseStream - Domain arn:aws:es:us-east-1:1234567890:domain/my-elastic-search is still being created.

有没有办法让Firehose的创建等到ES域创建完成之后?


为了以防万一,这里是我的 serverless.yml 文件的相关部分:

fyi,我正在使用 serverless-pseudo-parameters 插件来使用 #{AWS::Region}#{AWS::AccountId}

resources:
  Resources:

更新:

我现在已经修复了这个问题,以防万一这些细节对任何人都有帮助:

我将 DomainARN 属性 更改为 { "Fn::GetAtt": ["MyElasticSearch", "DomainArn" ] }

我最初动态生成 ARN 的原因是因为对于 "Fn::GetAtt",我最初尝试仅使用 Arn 而不是 DomainArn,但它不起作用。巧合的是,DomainArn 在最新版本中已被弃用,因此如果您使用的是最新版本,Arn 实际上是正确的。

Cloudformation 资源支持 DependsOn 属性。
