Cloud-Init on Technical Notes

Kubernetes 101

Sun, 26 Oct 2025 00:00:00 +0000

Kubernetes (K8s) is an open-source platform for automating the deployment, scaling, and management of containerized applications. It was built to work with Docker and depending on who you talk to, they’ll either say it’s hell or a piece of cake. The truth? If you’ve struggled with infrastructure (servers, networks), logged many hours with Linux, Docker and containers, it might not be that hellish and it’ll depend on how many hours you put in.

Like most of my posts, this is based on documenting my Home Lab, with hours of testing, things that stop working when you least expect it. But the good thing is you learn a ton and, if you’re a bit of a geek, you even have fun. Here’s my experience, with tricks, mistakes and everything I wish I’d known before starting.

ProxmoxVE Helper Scripts

If you have little experience it might be a bit daunting, which is why I recommend this wonderful project: Proxmox VE Helper-Scripts, where you’ll find hundreds of scripts to make your life easier installing CTs or VMs on top of your Proxmox.

Home Automation and Networking

Sat, 08 Apr 2023 00:00:00 +0000

I’m sharing my home networking setup with the option to knock on the door for on-demand access from the Internet. Today’s home networks end up supporting multiple services, and with the rise of home automation things get complicated, so I’ve decided to document it to keep track of everything in the future.

The number of devices grows and maintaining the network of a smart and automated home becomes a priority. I dedicate this post to those Geeks or Techies who, like me, have been deep into the complexity of networking in a home automation network for a long time.

Proxmox: VM from Template

Fri, 07 Apr 2023 00:00:00 +0000

Proxmox VE is a powerful and easy-to-use open-source virtualization platform that enables the deployment and management of virtual machines (VMs with KVM/QEMU) and containers (CTs based on LXC). Proxmox offers Templates to minimize the creation time of new instances of these virtual machines or containers.

In this post I focus on how to create my own Virtual Machine Templates along with a cloud-based image and cloud-init.
