This is the first part of a series where I'll share, step by step, how I built my own on-premise Kubernetes cluster, without relying on any cloud provider. The goal is to document the whole process — from environment preparation to a working cluster — as a reference for anyone studying the topic or looking to replicate the same setup at home or at work.
I used VPS (Virtual Private Server) and VM (Virtual Machine) for this cluster. However, it can also be set up on physical machines (Bare Metal).
Bye the end of this series, it will be easier to understand cloud clusters on AWS (EKS), Google (GKE) and Azure (AKS).
In this first part, we'll cover everything needed before installing any Kubernetes component: hardware requirements, basic network configuration, firewall rules, and a few mandatory operating system adjustments.
