Serverless Passive-Aggressive Password Generator

Because "password123" is a cry for help.

This project uses the aws-serverless-java-container library to run a full Spring Boot 3 application inside AWS Lambda. It demonstrates how to expose standard HTTP endpoints via AWS Lambda Function URLs without managing a dedicated server or complex API Gateway configuration.

Features

• Serverless Architecture: Runs entirely on AWS Lambda.
• Stateless: Pure Java logic with no database dependency.
• REST API: Exposes endpoints via standard HTTP methods.
• Roast Engine: Returns a commentary string with every generated password.

Prerequisites

• Java 17
• Maven 3.8+
• AWS Account

Deployment Guide

Follow these steps to deploy the application manually using the AWS Console.

1. Build the Application

Clone the repository and build the deployable zip file using Maven.

git clone https://github.com/HBrahmbhatt/aws-lambda-pwd-generator
cd aws-lambda-pwd-generator
mvn clean install

2. Create the Lambda Function

1. Log in to the AWS Management Console and navigate to the Lambda service.
2. Click Create function.
3. Select Author from scratch.
4. Enter a Function name (e.g., password-generator).
5. Set Runtime to Java 17.
6. Set Architecture to x86_64 (or arm64 if you configured your build for it).
7. Click Create function.

3. Upload Code

1. Navigate to the Code tab.
2. Click Upload from and select .zip or .jar file.
3. Upload the zip/JAR file generated in Step 1.
4. Click Save.

4. Configure Runtime Settings

1. In the Code tab, scroll down to Runtime settings and click Edit.
2. Change the Handler to match your bridge class: aws_lambda_springboot.aws_lambda_springboot_project.StreamLambdaHandler::handleRequest
3. Click Save.

5. Adjust Memory and Timeout

Spring Boot requires more resources than the default Lambda settings provide.

1. Navigate to the Configuration tab.
2. Select General configuration from the left menu and click Edit.
3. Set Memory to 512 MB (or higher).
4. Set Timeout to 30 seconds.
5. Click Save.

6. Enable Public Access

1. In the Configuration tab, select Function URL from the left menu.
2. Click Create function URL.
3. Set Auth type to NONE (allows public access).
4. Click Save.

7. Test

Copy the Function URL provided on the screen and open it in your web browser or Postman app. You should receive a JSON response containing a password and a roast as below.
