Systems & Infrastructure Lab 🛠️

Status: 🏗️ Under Active Development

This repository serves as a public showcase of my Infrastructure-as-Code (IaC) templates, monitoring configurations, and automation assets. My goal is to demonstrate a structured, scalable approach to systems administration, prioritizing automation, reliability, and security.


🛠 Technical Proficiency Matrix

Domain Technology & Tools Implementation Area
Automation Ansible, Terraform Proxmox Provisioning, OS Configuration
Containers Docker, Docker-Compose Game Service Stacks, Microservices
Monitoring Zabbix, Prometheus, Grafana LLD, Custom Dashboards, Alerting
Networking Bind9, Nginx, Wireguard DNS Management, Reverse Proxying
Systems Debian, Ubuntu, FreeBSD, Alpine Hardening, Kernel Tuning, Scripting

📂 Repository Structure

The lab is organized into logical layers, separating foundational platform provisioning from high-level service delivery.

  • infrastructure/ — Provisioning and configuration management.
    • terraform/ — Modular HCL configurations for Proxmox VM/LXC provisioning.
    • ansible/ — Playbooks for server hardening and software orchestration.
  • services/ — Production-ready workloads.
    • docker/ — Compose files for infrastructure services (Zammad, GLPI, Nginx).
    • networking/ — Configuration templates for Bind9, OpenVPN, and Wireguard.
  • observability/ — Monitoring and Visualization.
    • zabbix/ — Sanitized XML/YAML templates and custom discovery scripts.
    • grafana/ — JSON exports for infrastructure performance dashboards.
  • scripts/ — Automation utilities.
    • bash/ & python/ — Utilities for system health checks and API integrations.
