🧰 Kai Voss Sysadmin Toolbox

Welcome to the Kai Voss Sysadmin Toolbox, a curated and battle-tested collection of scripts, SOPs, and operational guides tailored for real-world Linux systems administration and DevOps.

This is not a tutorial site. It’s a working toolkit — the exact scripts and playbooks you'd use on-call, in production, or while automating infrastructure from scratch.

🧭 Who This Is For

  • Linux sysadmins managing servers and firewalls
  • DevOps engineers automating with Ansible, Docker, and CI/CD
  • Freelancers and consultants working on lean, real-world infrastructure
  • Platform engineers needing reusable SOPs and deployment logic

🧱 What's Inside

Area Contents
Scripts Cleanup, backup, system health, logging, monitoring
SOPs Security, incidents, provisioning, automation, CI/CD
Fun Tools MOTD scripts, CLI eye candy, Docker playgrounds
CI/CD GitLab templates for linting and CLI compliance
Docs This MkDocs-powered reference site

✨ Project Philosophy

  • No bloat. Everything here is used in real ops environments.
  • Modular. Copy only what you need — scripts are self-contained.
  • Documented. Every script and SOP includes usage or rationale.
  • Open. MIT licensed and contributions welcome.
