CloudOps Project — Full-Stack App Deployment with GitOps, CI/CD & AWS

This project demonstrates a production-grade full-stack web application deployed using AWS, Kubernetes (EKS), GitHub Actions, ArgoCD, Terraform, and other DevOps best practices. It is designed to showcase scalable, automated, and observable cloud infrastructure.

---

Architecture

The system consists of a React frontend, Go backend (Gin), and MySQL database on AWS, powered by GitOps and CI/CD pipelines.

---

Core Components

Frontend (React)

• Deployed to an S3 bucket and served via CloudFront.
• Also deployed as a containerized app on EKS (EC2) for SSR or dynamic needs.
• Exposed via AWS Load Balancer.

Backend (Go Gin)

• Containerized Go Gin service running as pods in EKS.
• Connects with RDS and S3 for data and media storage.
• Receives traffic from the frontend and routes internally.

Database & Storage

• MySQL (RDS) for persistent data storage.
• AWS S3 for user media uploads (images, files, etc.).

---

CI/CD & GitOps

Github Actions

• On every push to main:
  • Linting
  • Formatting
  • Test execution
  • Docker image builds (frontend & backend)
  • Push to Docker registry
  • Update Kubernetes manifests repo (Kustomize)

ArgoCD (GitOps)

• Monitors the manifests repo.
• Automatically syncs & deploys apps to EKS.
• Ensures environment matches Git state (declarative).

---

Infrastructure as Code

• Managed using Terraform:
  • VPC, Subnets
  • Internet Gateway, NAT Gateway
  • EKS cluster, node groups
  • RDS instances
  • S3 buckets
  • CloudFront distributions
  • Load Balancers
  • EC2
  • IAM roles & policies
