Over the past few weeks, I created​‍​‌‍​‍‌​‍​‌‍​‍‌ an 3 Tier To-Do application and put it live on Amazon EKS with the help of Docker, Kubernetes, and ALB Ingress Controller. The idea behind this project is to implement a 3 tier architecture from scratch. I created a basic To-Do application using Node JS, containerized the frontend, backend and database services, verified the configuration through Docker Compose, and managed the entire system in a Kubernetes environment that closely resembled production.

This work is a proof of concepts of a cloud-native app deployment, Kubernetes networking, ingress routing, and full DevOps ownership from development to cloud ​‍​‌‍​‍‌​‍​‌‍​‍‌rollout.

Pre-requisites Before diving in, I made sure I had:

• AWS Account: IAM user with permissions for EKS.
• Local Setup: NodeJS, pip, Docker, Git, AWS CLI, MongoDB.
• Image Registry: Docker Hub account

Tech Stack For this project, I used:

• Source Control: GitHub
• Containerization: Docker
• Image Registry: Docker Hub
• Orchestration: AWS EKS
• Application: NodeJS
• Database: MongoDB
• Networking / Routing: ALB Ingress Controller
