Hi, I’m Rogelio#
I’m a sysadmin passionate about real infrastructure: the kind that runs on actual hardware, not just in the cloud. I’ve spent years building and maintaining my own web infrastructure from home, learning along the way everything that courses don’t teach.
What you’ll find here#
This blog is my public technical notebook. I document what I do, what I break, and how I fix it. No generic examples — everything comes from real cases.
Main topics:
- Docker Infrastructure — compose, networking, volumes, reverse proxy with Traefik
- Monitoring — Prometheus, Grafana, Loki, real alerts
- Networks — WireGuard, fail2ban, SSH hardening, segmentation
- CI/CD — GitLab Runner, Hugo, automated deployments
- Automation — Python scripts, crons, AI agents
My current stack#
- Main server: home machine running Linux
- Replica: VPS on Clouding with automatic DNS failover
- Services: Traefik, Grafana, Loki, Prometheus, Listmonk, Hugo
- Private tunnel: WireGuard between both servers
