Devops Homelab

💼 DevOps Homelab Infrastructure

This project is a fully self-hosted, production-grade DevOps platform built from the ground up to simulate real-world infrastructure and deployment workflows. It was designed to go beyond tutorial-level setups by implementing a complete, automated system that mirrors how modern engineering teams build, ship, and monitor applications.

At its core, the system enables a seamless CI/CD pipeline where every code push automatically triggers a workflow that builds, tests, containerizes, and deploys applications to a cloud-based production environment in approximately three minutes, with zero manual intervention.

⚙️ Architecture Flow

Code → Gitea → Drone CI → Docker Build → Harbor Registry → 
Secure Deploy (WireGuard) → Oracle Cloud → Monitoring (Prometheus/Grafana)

🛠️ Tools & Why They Were Used

• Docker
• Used for containerization to ensure consistency across development, testing, and production environments.
• Gitea
• Self-hosted Git service chosen to maintain full control over source code and eliminate reliance on external platforms.
• Drone CI
• Lightweight, container-native CI/CD tool used to automate build, test, and deployment pipelines efficiently.
• Harbor
• Private container registry selected for secure image storage and built-in vulnerability scanning using Trivy.
• Prometheus
• Used for metrics collection to monitor system performance and service health in real time.
• Grafana
• Provides visualization dashboards for metrics, enabling easy monitoring and observability.
• Loki & Promtail
• Implemented for centralized logging, making it easier to track application behavior and debug issues.
• HashiCorp Vault
• Used for secure secrets management, ensuring sensitive data like credentials are not hardcoded.
• WireGuard
• Lightweight VPN used to securely connect the homelab environment to the cloud infrastructure.
• Oracle Cloud
• Chosen as the production environment to deploy and host applications in a real-world cloud setting.
• Portainer
• Used for simplified container management and visibility in the cloud environment.

🔐 Key Features

• Fully automated CI/CD pipeline (Git push → Production)
• Zero manual deployment steps
• Self-hosted infrastructure with full ownership
• Secure architecture with VPN and secrets management
• Real-time monitoring and centralized logging
• Production deployment in a cloud environment

🎯 Outcome

This project demonstrates the ability to design and manage end-to-end DevOps systems, combining automation, security, and observability to deliver reliable and scalable applications. It reflects real-world engineering practices and highlights strong problem-solving skills through the resolution of multiple infrastructure and deployment challenges.
