Using CI/CD to Deploy Infrastructure to AWS with Terraform through Git Action

✨ Objective:

Provision a full AWS infrastructure using Terraform that includes:

• VPC with public and private subnets
• EKS (Elastic Kubernetes Service) cluster
• RDS (MySQL) database
• Route 53 for DNS management
• GitHub Actions self-hosted runner for automation

We already set up a Dockerized self-hosted GitHub runner.

The steps below shows the modules used by terraform to configure our infrastructure.

Step 1 Terraform Provider & Backend Setup

1. Configured the AWS Provider in provider.tf:

   provider "aws" {
     region  = "eu-north-1"
     profile = "default"
   }
   
   

Step 2: VPC & Networking

Module used: module-vpc

1. Created the VPC with a CIDR block of 192.168.0.0/16.
2. Defined:
   • Public Subnets for the NAT Gateway and internet access.
   • Private Subnets for EKS nodes and RDS.
3. Added an Internet Gateway.
4. Deployed a NAT Gateway in one of the public subnets.
