AWS Athena 部署无服务器框架

Question

有人提示我必须如何将 !Ref und !Sub 从 CloudFormation 转换为 serverless.yml。

resources:
  Resources:
    AthenaCreateDatabaseQuery:
      Type: 'AWS::Athena::NamedQuery'
      Properties:
        Description: Run this query to initialize the Athena database
        QueryString: "CREATE DATABASE IF NOT EXISTS $(self:custom.etlDatabase};"
        Database: ${self:custom.etlDataBase}

• 在 Cloudformation 中，QueryString 属性 以 !Sub 开头， 带有 !Ref.
的数据库 属性

谢谢克里斯蒂安

!serverless.com 目前不支持 Sub（see this issue on GitHub) but you can use the following plugin https://gitlab.com/kabo/serverless-cf-vars

Whenever you want the cloudformation template to have a string that contains ${}, simply use #{} instead, and it will get transformed into correct ${} (with Fn::Sub inserted for you) in the cloudformation template before deployment.

或者按照建议使用自定义变量语法 here。两者都需要在 yaml 中使用 Fn::Sub 和 Fn::Ref 而不是短格式 !Sub 和 !Ref
