bin

The bin directory contains the entry point for the CDK application and scripts required to deploy the infrastructure.

Directory Structure

• README-bin.md: Documentation for the bin directory.
• cdk-rag-app.*: Entry point scripts for the CDK application.

Entry Point Script

The cdk-rag-app script is the main entry point for deploying the CDK stack. It initializes the application, loads environment variables, and defines the stack configuration.

Key Components

1. Source Map Support: Enables enhanced debugging by mapping runtime errors to the original source files.
2. AWS CDK App Initialization:
   • Creates an instance of the CDK app.
   • Loads the RagAppStack defined in the lib directory.
3. Environment Configuration:
   • Reads environment variables from a .env file to define the AWS account and region for deployment.
   • Supports environment-agnostic stacks or specialized deployments.

Example Script (cdk-rag-app.ts in case the original file was moditified or lost)

#!/usr/bin/env node
import 'source-map-support/register';
import * as cdk from 'aws-cdk-lib';
import { RagAppStack } from '../lib/cdk-rag-app-stack';

require('dotenv').config();

const app = new cdk.App();
new RagAppStack(app, process.env.CDK_STACK_NAME!, {
  env: { 
    account: process.env.CDK_DEFAULT_ACCOUNT, 
    region: process.env.CDK_DEFAULT_REGION 
  }
});
