DevSecOps Pipeline Demo

A demonstration of secure CI/CD pipeline implementation with integrated security scanning and GitOps deployment practices.

📋 Overview

This project showcases a complete DevSecOps pipeline that integrates security scanning tools directly into the CI/CD workflow. The pipeline includes static code analysis, container security scanning, and automated deployment to staging environments.

🛠️ Technologies Used

• CI/CD: GitLab CI/CD
• Container: Docker
• Security Scanning: SonarQube, Trivy, CodeQL
• Deployment: ArgoCD (GitOps)
• Infrastructure: Kubernetes, Helm
