通過Cloudformation將角色添加到AWS Cognito身份池

Question

我正在嘗試編寫CloudFormation模板，以使用Google身份驗證和使用預先存在的角色創建新的Cognito身份池。

此代碼創建與谷歌認證一個新的身份池 -

Resources: 
cognitoid: 
    Type: "AWS::Cognito::IdentityPool" 
    Properties: 
    "AllowUnauthenticatedIdentities": false 
    "SupportedLoginProviders": { "accounts.google.com": "<Google client id>" } 

的角色，AWS::Cognito::IdentityPool不必須的性能，適於安裝一個角色什麼。

Answer 1

終於能夠使它發揮作用 -
