Hi, I’m Dominik.
I work as a Linux System Administrator and spend most of my time building, breaking, and rebuilding infrastructure. Both at work and in my homelab. Most of what you’ll read here isn’t theoretical: it runs 24/7 in my own environment and gets improved as I learn.
What I work with
Daily: Linux (AlmaLinux, Debian), nginx, Apache, LiteSpeed, Plesk, PHP stacks, SSL/TLS, Docker & Podman
Homelab: Proxmox, OPNsense, WireGuard, Ansible, monitoring & backup stacks
Explored & retired: Kubernetes (RKE2), Flux/GitOps, n8n — I ran a full GitOps cluster and learned a lot, then went back to plain Docker because it’s the right tool for three hosts and a VPS. Sometimes the lesson is knowing when not to use the fancy thing.
Why this blog exists
I document what I build: running game servers in containers, migrating between providers, monitoring and backup strategies, and the mistakes I made along the way, so you don’t have to make them too.
