Projects

Homelab "protoss-cluster"

Step-by-step migration of the homelab to declarative provisioning: OpenTofu creates containers, Ansible configures them, CI checks every change.

Homelab

My homelab is my laboratory: this is where I try technologies before I take them seriously, and where I run everything I can self-host. It serves the whole family in production — so outages get noticed.

Cluster nodes
3 × Proxmox VE (HA)
Services
30+ self-hosted
Backup
Proxmox Backup Server, versioned
Docs
100% as a Git repo (docs as code)
Request flow from outside in

How I Work

  1. Docs as code

    Every decision, runbook and inventory lives versioned in a Git repo. What is not documented does not exist.

  2. One service, one responsibility

    Clear boundaries: one service per container, one place per piece of information, no duplicates.

  3. Security by default

    Hardened containers, minimal privileges, encrypted secrets, no direct access from outside.

  4. Automate instead of repeat

    Anything done manually twice becomes a script, a playbook or a pipeline the third time.

  5. Understand first, build second

    New technologies are evaluated in the lab, documented, and only then used in production.
