Installing Cilium and Multus on Talos OS for Advanced Kubernetes Networking

Luka Krapić — Tue, 05 Aug 2025 15:25:19 +0100

In a previous article, we explored deploying a highly available Kubernetes cluster using Talos OS, running on Proxmox and automated with Terraform. That setup provided a clean, immutable base for Kubernetes. However, its default networking stack—based on Flannel and kube-proxy—offers limited capabilities when it comes to modern network observability, performance tuning, or multi-interface pods.

In this guide, we’ll walk through installing Cilium as the primary CNI and Multus as a secondary CNI meta-plugin on Talos OS. This combination introduces support for advanced features such as eBPF-powered networking, per-pod visibility, and attaching pods to multiple physical or logical networks.

Deploying a Highly Available Kubernetes Cluster on Proxmox with Terraform and Talos OS

A highly available Kubernetes cluster in a homelab setup creates opportunities to test distributed systems, automation, and failure recovery under real-world conditions. This guide walks through one approach to building such a cluster using Proxmox for virtualization, Terraform for provisioning, and Talos OS for running the Kubernetes nodes.

This setup provides declarative infrastructure and immutable operating systems, eliminating the need for traditional Linux administration—no SSH, no shell, and no drifting configuration. The result is a consistent, secure, and maintainable cluster architecture suitable for long-term experimentation or light production use.

Building a Home Virtualization Server With Proxmox

Running a dedicated virtualization server at home is a practical way to centralize always-on workloads like self-hosted services, infrastructure tooling, or test environments. In this post, we’ll walk through one possible setup using Proxmox VE as the hypervisor, Ansible for configuration management, and Packer to create reusable virtual machine templates.

The configuration is tailored for a single-node homelab using a compact mini-PC, but the principles can be adapted to larger or different environments. All playbooks, templates, and configuration files used in this guide are available in this GitHub repository for reference and reuse.

Setting Up a Synology NAS for Your Homelab: The Complete Guide

Luka Krapić — Sat, 26 Apr 2025 13:07:10 +0100

When building or expanding a homelab, setting up a Synology NAS is one of several strong options for managing local storage, backups, and remote access. It’s a flexible platform that offers many features typically found in enterprise storage solutions, but in a form factor and price point that’s accessible to home users.

If you’re considering moving more of your important files, services, or backups off of third-party cloud providers and into a system you control, a NAS can be a great fit. (You can read more about why I personally chose Synology here.

Cloud Storage Is Getting Expensive — Here’s Why I Switched to Synology NAS

Luka Krapić — Sat, 19 Apr 2025 19:13:10 +0100

These days, everything lives in the cloud — photos, videos, documents, backups. And for a while, it felt like cloud storage was the perfect solution: easy to access, always backed up, and simple to share with others.

But if you’re like me and deal with a lot of files — especially big ones like videos or high-res photos — you’ve probably hit the same wall I did: cloud storage gets really expensive, really fast.

Building SOHO Network With Ubiquiti UniFi: Step-By-Step Guide

Luka Krapić — Sun, 22 Sep 2024 16:56:47 +0100

In this guide, we’ll take you through building a segmented, secure SOHO (Small Office/Home Office) network using Ubiquiti UniFi hardware. The network will be tailored to isolate different types of traffic, set up VLANs for specific use cases, and apply strong firewall rules to protect sensitive data and infrastructure.

While the principles outlined here are generally applicable to most networks, this implementation is specifically designed for UniFi OS version 4.06 and Network Application version 8.4.62.

Building An AI Playground With Ollama And Open WebUI: A Hands-On Introduction For Beginners

Large Language Models (LLMs) have been making waves in the field of artificial intelligence (AI) for quite some time, and their popularity continues to soar. These advanced models have the remarkable ability to understand, generate, and respond to human language with unprecedented accuracy and depth. With this surge in interest comes the rise of open source solutions that enable individuals and organizations to host LLMs locally.

In this blog post we will explore how to turn your existing local computer/server into a simple ai server.
