A systems administrator needs to know the state of their server at any moment. This project is a Bash script that audits a RHEL server and generates a structured report covering disk space, service...
This is the complete roadmap I’m following — from Service Desk Analyst to Junior Systems Administrator, then all the way to Senior Systems Engineer. Every module has a side project. No theory witho...
The last piece of Module 08. Variables and templates handle configuration — Vault handles credentials. A password committed in plain text to GitHub is a password that has leaked. Repo: biroue10/an...
Module 08 continues. The skeleton from last session (roles for Nginx, MariaDB, PHP-FPM) worked — but every value was hardcoded. Today: variables to centralise config, handlers to restart services o...
Every concept from the roadmap gets turned into a real, versioned, public project. This category documents each project — architecture decisions, problems encountered, SELinux fixes, and lessons le...
Containers have become the standard packaging format for applications. This category documents everything from building Docker images to operating production Kubernetes clusters. What this categ...
Security is not a feature you add at the end — it is a layer you build into every decision. This category documents system hardening, SELinux, certificate management and compliance on RHEL 10. W...

Managing one server manually is feasible. Managing fifty is not. This category documents the automation stack — from Ansible playbooks to Terraform infrastructure provisioning and GitOps workflows....
A production system that goes fully offline for a single server failure is not production-ready. This category documents how to design and operate systems that survive hardware failures, maintenanc...
