Creates a basic AWS Cognito setup with a mandatory 8 character long password policy and dynamic schema support.

Please note the variable ignore_changes in the ./main.tf file is used to prevent re-deployments from occurring.

There's no built in support yet for;

• SNS Email sending and template, instead it uses the built in email support with sending limitations.
• SMS sending

To add a Federation, provide the identity_provider_map with the appropriate configuration for the supported Fedartion, in this case, Google.

To then enable that login provider for your Cognito identity pool, add supported_login_providers configuration.

module "cognito" {
  source = "../../modules/cognito"

  namespace         = var.namespace
  resource_tag_name = var.resource_tag_name
  region            = var.region

  cognito_identity_pool_name     = var.cognito_identity_pool_name
  cognito_identity_pool_provider = var.cognito_identity_pool_provider

  # User Pool Client Configuration
  allowed_oauth_flows          = [ "implicit" ]
  allowed_oauth_scopes         = [ "aws.cognito.signin.user.admin" ]
  callback_urls                = [ "https://google.com" ]
  supported_identity_providers = [ "Google" ]

  supported_login_providers = {
    "accounts.google.com" = "dfsfsf.apps.googleusercontent.com"
  }

  identity_provider_map = {
    google = {
      provider_name    = "Google"
      provider_type    = "Google"
      authorize_scopes = "email"
      client_id        = "dfsfsf.apps.googleusercontent.com"
      client_secret    = "sdfsfasdfafsafsafsfsdf"

      attribute_mapping = {
        email    = "email"
        username = "sub"
      }
    }

  schema_map = [
    {
      name                = "email"
      attribute_data_type = "String"
      mutable             = false
      required            = true
    },
    {
      name                = "phone_number"
      attribute_data_type = "String"
      mutable             = false
      required            = true
    }
  ]
}
