TechNova DevOps Project :- This is a beginner-friendly DevOps project to learn how to automate deployments using:

• Node.js (Simple web app)
• Docker (Containerize the app)
• Jenkins (CI/CD tool)
• AWS EC2 (Deploy app to the cloud)
• Terraform (Create EC2 server using code)
• GitHub + DockerHub (Store code and Docker image)

• Project Folder Files File/Folder Description

• hello.js – Node.js file – a basic web app (runs on port 3000)
• Dockerfile – Builds a Docker image from hello.js
• package.json – Lists Node.js packages (dependencies)
• node_modules/ – Auto-generated folder when you run npm install
• terraform/ – Contains main.tf and variables.tf to launch EC2
• main.tf – Terraform script to create AWS EC2 server
• variables.tf – Stores EC2 configuration variables
• README.md – This file explaining your project

Here’s what each file or folder does:

• Project Setup (Step-by-Step) 1. Clone Your Repository

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

2. Install Node Modules

npm install

3. Run Node.js App

node hello.js

Visit: http://localhost:3000

• ■ Docker Setup 4. Build Docker Image

docker build -t technova-app .

5. Run Docker Container

docker run -p 3000:3000 technova-app

Visit: http://localhost:3000

• ■■ Terraform Setup (AWS EC2) 6. Initialize Terraform

cd terraform
terraform init

7. Apply Terraform

terraform apply

Respond with yes

• Jenkins Setup Go to Jenkins > Manage Jenkins > Credentials > (global) Add these:

• ID: github-token (your GitHub token)
• ID: dockerhub-cred (your DockerHub login) Create pipeline job to:
• Clone repo
• Build image
• Push to DockerHub
• Deploy to EC2
  • Important: .gitignore Add this to .gitignore to avoid uploading sensitive files:

node_modules/
technovat1.pem
terraform.tfstate
