The End of 'It Works on My Machine': How Distrobox Saves Your PC!

Mon, 16 Mar 2026 10:00:00 -0300

Have you ever experienced the frustration of having to install an older version of Python to maintain a legacy project, and then immediately needing the latest version of Node.js for another project, only to see your system packages conflict?

Your local machine, once clean and sacred, begins to turn into the famous “it works on my machine” scenario. Full of broken PPAs, version managers fighting each other, and accumulated junk.

How to Install Apache CloudStack with Ansible - Video Tutorial

Wed, 28 Jan 2026 00:00:00 -0300

If you want to learn how to install Apache CloudStack in an automated way using Ansible, I’ve prepared a complete video tutorial showing the entire process step by step.

What you will learn

In this video tutorial, I demonstrate in practice how to:

🚀 Set up the environment for CloudStack installation
⚙️ Use Ansible to automate the entire installation
🗄️ Configure MySQL Server for CloudStack
📦 Configure NFS for Primary and Secondary Storage
🖥️ Install and configure the Management Server
🔧 Download and configure System VM Templates
✅ Validate the installation and access the web interface
☸️ Live Demo: Install a Kubernetes cluster using CloudStack CKS

Why automate with Ansible?

Manual CloudStack installation is a complex process that can take hours and is prone to errors. With Ansible, you can:

Is NGINX Ingress Controller Dead? Meet NGINX Gateway Fabric

Sat, 06 Dec 2025 00:00:00 -0300

If you work with Kubernetes, you’ve probably used or at least heard of the NGINX Ingress Controller. For a long time, it was the default choice for exposing applications to the outside world. But recently, F5 (owner of NGINX) announced the deprecation of the project.

Nginx vs Traefik vs Caddy: Which Reverse Proxy to Choose?

Wed, 26 Nov 2025 00:00:00 -0300

Choosing the right Reverse Proxy is one of the first and most important decisions when building a Homelab or setting up a production infrastructure. It is the gateway to your services, responsible for routing, SSL termination, and security.

For years, Nginx has been the undisputed king. But recently, “Cloud Native” options like Traefik and modern simplifiers like Caddy have gained massive popularity.

In this post, we will compare these three giants to help you decide which one is best for your use case.

Goodbye Proxmox? Why I Migrated My Homelab to Apache CloudStack

Mon, 24 Nov 2025 00:00:00 -0300

Are you still managing your VMs on Proxmox? If you’re looking to advance your cloud computing studies and get closer to real enterprise environments, it might be time to rethink your virtualization stack. In this post, I’ll share the reasons that led me to migrate my homelab from Proxmox and OpenStack to Apache CloudStack, and how this decision transformed my learning experience.

Simplify Your Projects: How to Use GitHub Template Repositories

Tue, 18 Nov 2025 00:00:00 -0300

🚀 Tired of setting up projects from scratch and copying and pasting the same CI/CD workflow files over and over? No more rework! In this post, we’ll solve this problem once and for all using GitHub Template Repositories.

The Problem: Constant Rework

Every time you start a new project, you need to:

GitHub Actions Matrix Strategy: Testing Multiple Versions Simultaneously

Sun, 24 Aug 2025 00:00:00 -0300

Testing your code on just one version of Node.js, Python, or Ruby is risky. What if your code breaks on Python 3.9 but works on 3.12? What if there are Windows-specific bugs you don’t catch on Linux? GitHub Actions Matrix Strategy solves this elegantly.

The Problem: Multi-Version Compatibility

Imagine this common scenario:

 
 YAML
 
# Simple workflow
jobs:
 test:
 runs-on: ubuntu-latest
 steps:
 - uses: actions/checkout@v4
 - uses: actions/setup-node@v4
 with:
 node-version: '20'
 - run: npm test

Tue, 24 Jun 2025 00:00:00 -0300

If you work with CI/CD on GitHub Actions, you’ve probably found yourself copying and pasting the same YAML code between different workflows. What if I told you there’s a much more elegant and professional way to do this? In this post, I’ll show you how Reusable Workflows can revolutionize your CI/CD pipeline.
