🚀 GitLab CI/CD Docker Deployment

📖 Overview

This project demonstrates the implementation of a Continuous Integration and Continuous Deployment (CI/CD) pipeline using GitLab. The application is containerized using Docker, and GitLab CI/CD automates the build process whenever code is pushed to the repository.

The project showcases essential DevOps practices including version control, containerization, pipeline automation, and deployment workflows.

📊 Pipeline Monitoring

Pipeline execution can be monitored through:

Build → Pipelines

GitLab provides:

• Build Status
• Job Logs
• Execution Duration
• Success/Failure Reports

---

✅ Results
