Building a Smart Holiday Home Hub with Docker, Home Assistant, and Node-RED on Raspberry Pi 5

At our holiday home — a quiet place we visit just once or twice a year — I wanted to know exactly what’s happening there, even when we’re not around. Call it freak-control if you will, but when you have a heating system running through the winter and the power tends to drop every now […]

VMware vSphere – Automating VM Deployment with Ansible and GitLab CI/CD – Part 3

In the last post I proved the flow locally: Ansible talks to vCenter, clones from a template, and the VM comes up with our settings. That was the “manual gear.” Now I want the “automatic gear”—a GitLab pipeline that runs the same steps for me, consistently, from any commit. My goals are simple: keep secrets

VMware vSphere – Automating VM Deployment with Ansible and GitLab CI/CD – Part 2

In this post we move from lab setup to hands-on automation. The goal is to provision virtual machines on vSphere automatically by combining Ansible playbooks with a GitLab CI/CD pipeline. Everything lives as code in a Git repository: VM definitions, playbooks, and the pipeline that runs them. With a single commit, GitLab triggers Ansible, which

VMware vSphere – Automating VM Deployment with Ansible and GitLab CI/CD – Part 1

A few months ago, when I first came across a project where Ansible and GitLab CI/CD were used to automate VM deployments in VMware vCenter, I wasn’t directly responsible for writing the playbooks. My role was more on the VMware side — managing vCenter, handling ESXi administration, and preparing the YAML host files that Ansible

How to Increase Disk Size of an Ubuntu Linux VM in vSphere

When managing virtual machines in VMware vSphere, it’s common to run out of disk space over time. Fortunately, expanding a virtual disk is straightforward, but it involves both changes in vSphere and inside the guest operating system. In this guide, I’ll walk you through the steps to increase the disk size of an Ubuntu Linux
