Hi Hand GIF, I'm Marc Schäfer

Welcome to my GitHub Profile!

I'm a System Administrator from Germany 🇩🇪

Linux Docker Kubernetes Azure Prometheus Traefik

🙋‍♂️ About Me

  • 👨‍💻 System Administrator since 2020
  • 🏠 HomeLab Enthusiast: Building, ,experimenting, breaking, and refining infrastructures HomeLab!
  • 🗝️ Automation Advocate: If it can be automated, it’s on my list (sometimes even the ones that stubbornly resist).
  • 🔐 Open Source & Security Buff: Passionate about all things Linux, open source, and ensuring our digital realms stay secure.
  • ☁️ Hybrid Solutions Fan: On-premises? Cloud? Why not both! I’m all in for mixing the best of both worlds.
  • 💡 Always Experimenting: Whether it’s monitoring, CI/CD, or container orchestration, I love diving into new tech adventures. Feel free to reach out if you want to chat about IT innovations or share tales from your own HomeLab escapades!

🧑‍🔬 The HomeLab Chronicles 🤓

Welcome to my HomeLab—a place where engineering brilliance meets "Oh wow, why is this not working again?"

My (Digital) Kingdom

  • Raspberry Pi Talos Clusters – Prod & Dev:
    Armed with Compute Modules 4 and 5 running on ComputeBlades, these micro dynamos orchestrate chaos with Rook/Ceph as their trusty storage backbone. Tiny but mighty! 🛠️🍓

  • Enterprise-ish Network:
    A Frankenstein’s monster of vendor love:

    • Unifi: Covering WiFi, cameras, and IoT serenades
    • MikroTik & Ruckus switches: Because one brand is too easy
    • Firewalls in flux: Migrating from pfSense to OPNsense because we all need some existential troubleshooting in our lives
  • High-octane Networking: 🚀
    The backbone is fully 10Gig, with 25Gig love reserved for key systems (looking at you, storage and hypervisors). If bandwidth were attention span, my network would be a PhD scholar.

  • Hypervisors to rule them all:

    • vSphere & Proxmox: Coexisting peacefully—for now.
    • Hardware: HP Gen9 servers, sleek Dell Gen15 machines, and some spry older Supermicro servers lurking in the corner. Perfect for when I need to test something wild and dangerous on bare metal. 🔧💻

Guides & Stories

Want a peek into the madness? 🤫

This is just the teaser trailer—detailed guides, war stories, and lessons learned will be coming soon to a blog or repo near you. Stay tuned! 🚧

I will share some stories in the future

⬢ Because life is better when it's configured, overengineered, and occasionally on fire.
