A self-hosted DevOps ecosystem deployed on a Raspberry Pi, featuring a fully automated Jenkins pipeline, Nginx reverse proxying, and a Prometheus/Grafana monitoring.
The project is hosted on a local Raspberry Pi made accessible via Port Forwarding on a public IP.
CI/CD Pipeline (Jenkins)
- Custom Branching: Supports dynamic builds based on git branches.
- Security: Trivy integration for filesystem and image scanning.
Monitoring (Prometheus & Grafana)
- Real-time system and container metrics.
- Visualization via pre-made, optimized dashboards.
Issue: By default, the Raspberry Pi OS environment was running a 32-bit Docker engine, causing compatibility issues with modern DevOps tool images (like newer Jenkins/Grafana builds).
Solution: Conducted a deep-dive audit of the system architecture, application requirements, and kernel support. I successfully migrated the environment to 64-bit Docker, ensuring long-term stability and image compatibility.
Issue: Encountered volume mapping failures when using DooD. The Jenkins container couldn't resolve paths correctly when communicating with the host’s Docker socket.
Solution: To ensure persistence and proper execution, I standardized the volume mounting to the local host path /var/jenkins_home, aligning the container’s internal state with the physical storage of the Pi.
Infrastructure: Raspberry Pi, Docker, Docker Compose
