AWS Serverless Infrastructure with Terraform

This repository contains the Terraform configuration files for deploying a serverless infrastructure on AWS. The infrastructure consists of a VPC, private subnets, RDS instances, API Gateway, and Lambda functions. All resources are created and managed using Terraform.

Overview

The infrastructure is organized as follows:

• VPC with private subnets
• RDS instances with security groups
• API Gateway for managing access to Lambda functions
• Lambda functions with VPC access and IAM roles

Getting Started

Follow these steps to deploy the infrastructure:

1. Ensure you have Terraform installed on your system. You can download Terraform here.

2. Clone this repository and navigate to the project directory.

git clone https://github.com/FDR123/terraform-playground.git
cd terraform-playground

3. Navigate to the lambdas/user_api folder and make any necessary changes to the Lambda function.

4. In the lambdas/user_api folder, run the following command to bundle the Lambda function: npm run bundle

5. Navigate to the terraform folder and initialize Terraform:

cd terraform
terraform init

6. Deploy the infrastructure by running the terraform apply command. This will prompt you to confirm the changes before proceeding: terraform apply

To destroy the infrastructure, run terraform destroy.

Infrastructure Details

• VPC: The VPC is created with a CIDR block of 10.0.0.0/16, with DNS support and hostnames enabled.
• Subnets: Two private subnets are created in the VPC, each in a different availability zone.
• RDS: A PostgreSQL RDS instance is created within the VPC, with a security group that allows inbound traffic from the Lambda security group.
• API Gateway: An API Gateway is created for each Lambda function, with a REST API that integrates with the Lambda function.
• Lambda Functions: Lambda functions are created with the necessary IAM roles and VPC access. The Lambda function's source code is deployed using Terraform.
