DevOps Assignment 1: CI/CD Pipeline with GitHub Actions and SonarQube

Project Overview This project demonstrates a fully automated CI/CD pipeline for a full-stack web application using GitHub Actions for automation, SonarQube for code quality analysis, and Railway for deployment.

Problem Statement Manual deployment and code quality checks slow down development and increase errors. The goal of this project is to:

• Automate the build, test, and deployment process.
• Ensure code quality using SonarQube.
• Deploy the application automatically to Railway after successful checks.

Tech Stack

• Frontend: React
• Backend: Node.js with Express
• CI/CD: GitHub Actions
• Code Quality: SonarQube
• Deployment: Railway

CI/CD Pipeline with GitHub Actions Workflow Steps:

1. Trigger on push/pull request: The pipeline runs automatically.
2. Install dependencies: Installs required packages.
3. Run tests: Ensures code correctness.
4. SonarQube Analysis: Scans the code for bugs, vulnerabilities, and code smells.
5. Deploy to Railway: If all checks pass, the app is deployed automatically.

SonarQube Integration To analyze code quality:

1. Create a SonarCloud account.
2. Generate a SonarQube Token.
3. Store it in GitHub Secrets as SONAR_TOKEN.
4. Modify the GitHub Actions workflow to include SonarQube analysis.

Deployment on Railway

1. Create an account on Railway.
2. Connect your GitHub repository.
3. Railway will automatically deploy the latest changes.

Conclusion This project automates the entire CI/CD workflow and ensures high code quality. With GitHub Actions and SonarQube, every commit is tested and deployed seamlessly.
