I work with a diverse set of tools and technologies on a daily basis:

Linux Alpine Linux Docker Kubernetes ArgoCD Traefik Azure Prometheus Jenkins Keycloak CheckMK Ansible Bash Git Python

πŸ§‘β€πŸ”¬ The HomeLab Chronicles πŸ€“

Welcome to my HomeLabβ€”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! πŸ› οΈπŸ“

  • 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: πŸš€
    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 peacefullyβ€”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. πŸ”§πŸ’»

Guides & Stories

Want a peek into the madness? 🀫

This is just the teaser trailerβ€”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

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