CloudFormation modelli
Il cloudformation-mortgage-flow-setup.zip file scaricato contiene i seguenti file:
-
deploy.sh— Uno script di shell che distribuisce le tue risorse e prepara il CloudFormation modello principale che utilizzerai. -
artifacts— Una cartella che contiene file.zip con funzioni per i modelli dell'agente e della knowledge base:-
Funzioni Lambda per i gruppi di azioni dell'agente
-
agent_loan_calculator.zip -
mls_lookup.zip -
loader_deployment_package.zip
-
-
Funzioni per la configurazione della knowledge base
-
custom-resource-lambda.zip -
opensearchpy-layer.zip -
provider-event-handler.zip
-
-
-
api-schema— Una cartella che contiene schemi API per gruppi di azioni. -
knowledge-base-data-source— Una cartella che contiene il PDF della Guida alla vendita di Fannie Mae. -
templates— Una cartella che contiene i modelli per le risorse di questo flusso, sia in formato JSON che YAML:-
main-stack-tmp— Il modello principale che distribuisce i modelli rimanenti come pile annidate. Questo file viene trasformato inmain-stackseguito all'esecuzione dello script di distribuzione. -
guardrails-template— Il modello per il guardrail da associare all'agente. -
prompts-template— Il modello per i prompt da utilizzare in flow. -
kb-role-template— Il modello per il ruolo della knowledge base, da utilizzare sia dal modello che dal OpenSearch modello della knowledge base. -
oss-infra-template— Il modello per l'Amazon OpenSearch Serverless Vector Store da utilizzare per la knowledge base. -
kb-infra-template— Il modello per la knowledge base sui mutui ipotecari da associare all'agente. -
agent-template— Il modello per l'agente di elaborazione dei mutui da utilizzare nel flusso. -
mortgage-flow-template— Il modello per il flusso di elaborazione dei mutui che combina tutte le risorse.
-
-
README.md— Un file README che descrive i passaggi per l'utilizzo del modello.
I seguenti argomenti mostrano i AWS CloudFormation modelli utilizzati per ogni pila. Lo stack principale distribuisce gli stack rimanenti come pile annidate.
Argomenti
Stack principale
Lo stack principale definisce i parametri che è possibile definire quando si carica il modello. Questi valori vengono passati a ciascuno degli stack annidati rimanenti. Lo script di distribuzione sostituisce MortgageFlowBucket il valore predefinito del Q01pS3BucketName parametro con il bucket S3 effettivo che contiene le risorse distribuite dallo script.
