Node.js API on Amazon EKS

This project demonstrates deploying a Node.js API onto an Amazon EKS (Elastic Kubernetes Service) cluster using Kubernetes manifests. It includes configuration for pods, service accounts, deployments, and services to run the application on AWS-managed Kubernetes.

🚀 Project Overview

• Backend: Node.js + Express
• Containerization: Docker
• Orchestration: Kubernetes (EKS)
• Cloud Provider: AWS
• Networking: Exposes API via Kubernetes Service (LoadBalancer / ClusterIP)

🛠️ Setup & Deployment

1. Clone this repository

git clone https://github.com/<your-username>/<your-repo>.git
cd <your-repo>

2. Build and push the Docker image

Replace <account_id>, <region>, and <repo-name> with your details.

# Authenticate Docker with ECR
aws ecr get-login-password --region <region> | docker login --username AWS --password-stdin <account_id>.dkr.ecr.<region>.amazonaws.com

# Build and tag the image
docker build -t node-api .

# Tag for ECR
docker tag node-api:latest <account_id>.dkr.ecr.<region>.amazonaws.com/<repo-name>:latest

# Push to ECR
docker push <account_id>.dkr.ecr.<region>.amazonaws.com/<repo-name>:latest
