MERN Stack CI/CD Pipeline

Project Overview

Designed and implemented a robust CI/CD pipeline for a full-stack MERN application using GitLab CI/CD. The pipeline automates build, security scanning, Docker image creation, vulnerability analysis, and deployment readiness using Docker Compose.

Key Achievements

• Containerized React frontend, Node.js backend, and MongoDB using Docker Compose.
• Designed a multi-stage GitLab CI/CD pipeline for build, scan, and image creation.
• Integrated Trivy for filesystem and container image vulnerability scanning.
• Enforced code quality gates using SonarQube analysis.
• Implemented parallel CI jobs for frontend and backend to reduce pipeline time.
• Ensured MongoDB data persistence using Docker volumes.
• Automated Docker image tagging using pipeline identifiers.
• Improved deployment consistency and reduced manual intervention.
