Troubleshooting Tips

Service won’t start: Check logs with journalctl -u servicename or Docker logs with docker logs container-name

Network connectivity issues: Test with ping 8.8.8.8 (internet) and ping hostname.local (local network)

Storage full: Check disk space with df -h, clean Docker images with docker system prune

Performance issues: Monitor CPU and RAM with top command, check temperatures with vcgencmd measure_temp

Conclusion

Raspberry Pi 5 projects teach practical Linux, networking, and DevOps skills while building genuinely useful home infrastructure. Start with Pi-hole or Plex, gradually progressing to more complex projects. After completing these projects, you’ll understand networking, containerization, automation, and system administration—skills valuable in IT careers.
