Project of a AWS Lambda with API Gateway, and DynamoDB. Made with Terraform

This project sets up an Java 21 AWS Lambda function using Spring Boot 3, which is triggered by an API Gateway and interacts with a DynamoDB table to manage user data. The DynamoDB table stores user data with fields uuid, email, and created_at.

Requirements

  • Java 21
  • Maven
  • AWS CLI (configured)
  • Terraform

Setup Instructions

  1. Clone the repository:

    git clone https://github.com/ccallazans/aws-lambda-spring-boot.git
cd aws-lambda-spring-boot

  2. Build the Spring Boot project:

    ./mvnw clean package

  3. Deploy the infrastructure using Terraform:

    • Go to /terraform folder 
      cd terraform
    • Initialize Terraform: 
      terraform init
    • Apply the Terraform configuration: 
      terraform apply

Usage

The API Gateway exposes two endpoints to interact with the user data:

  1. GET /users: Retrieve all users

    curl -X GET https://your-api-id.execute-api.us-east-1.amazonaws.com/your-stage/users

  2. POST /users: Create a new user

    curl -X POST https://your-api-id.execute-api.us-east-1.amazonaws.com/your-stage/users \
-H "Content-Type: application/json" \
-d '{"email": "user@example.com"}'
