# CloudFormation Vorlagen
-Vorlagen

Der Download-Datei `cloudformation-mortgage-flow-setup.zip` enthält die folgenden Dateien:
+ `deploy.sh`— Ein Shell-Skript, das Ihre Ressourcen bereitstellt und die CloudFormation Hauptvorlage vorbereitet, die Sie verwenden werden.
+ `artifacts` – Einen Ordner, der ZIP-Dateien mit Funktionen für den Agenten und Vorlagen für die Wissensdatenbank enthält:
  + Lambda-Funktionen für die Aktionsgruppen des Agenten
    + `agent_loan_calculator.zip`
    + `mls_lookup.zip`
    + `loader_deployment_package.zip`
  + Funktionen zum Einrichten der Wissensdatenbank
    + `custom-resource-lambda.zip`
    + `opensearchpy-layer.zip`
    + `provider-event-handler.zip`
+ `api-schema` – Einen Ordner, der API-Schemas für Aktionsgruppen enthält
+ `knowledge-base-data-source` – Einen Ordner, der die PDF-Datei für [Fannie Mae's Selling Guide](https://selling-guide.fanniemae.com/) enthält
+ `templates` – Einen Ordner, der die Vorlagen für die Ressourcen in diesem Flow sowohl im JSON- als auch im YAML-Format enthält:
  + `main-stack-tmp` – Die Hauptvorlage, die die verbleibenden Vorlagen als verschachtelten Stack bereitstellt. Diese Datei wird in `main-stack` konvertiert, nachdem das Bereitstellungsskript ausgeführt wurde.
  + `guardrails-template` – Die Vorlage für den Integritätsschutz, der mit dem Agenten verknüpft werden soll
  + `prompts-template` – Die Vorlage für die Prompts, die im Flow verwendet werden sollen
  + `kb-role-template`— Die Vorlage für die Wissensdatenbank-Rolle, die sowohl von der OpenSearch Vorlage als auch von der Wissensdatenbank-Vorlage verwendet werden soll.
  + `oss-infra-template`— Die Vorlage für den Amazon OpenSearch Serverless Vector Store, die für die Wissensdatenbank verwendet werden soll.
  + `kb-infra-template` – Die Vorlage für die Wissensdatenbank des Hypothekenkredits, die mit dem Agenten verknüpft werden soll
  + `agent-template` – Die Vorlage für den Verarbeitungsagenten der Hypothek, der im Flow verwendet werden soll
  + `mortgage-flow-template` – Die Vorlage für den Verarbeitungs-Flow der Hypothek, der alle Ressourcen kombiniert
+ `README.md` – Eine README-Datei, in der die Schritte zur Verwendung der Vorlage beschrieben werden

Die folgenden Themen zeigen die CloudFormation Vorlagen, die für jeden Stapel verwendet werden. Der Haupt-Stack stellt die übrigen Stacks als [verschachtelte Stacks](https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/using-cfn-nested-stacks.html) bereit.

## Haupt-Stack


Der Haupt-Stack definiert die Parameter, die Sie beim Hochladen der Vorlage definieren können. Diese Werte werden an jeden der verbleibenden verschachtelten Stacks weitergegeben. Das Bereitstellungsskript ersetzt *MortgageFlowBucket* den Standardwert des `Q01pS3BucketName` Parameters durch Ihren tatsächlichen S3-Bucket, der die vom Skript bereitgestellten Ressourcen enthält.
