Building a production-ready Kubernetes cluster from scratch

From hardware assembly to network configuration, this guide will guide you through the process of building a production-ready Kubernetes cluster from scratch using Raspberry Pi devices.

Welcome to my new guide on building a production-ready Kubernetes cluster from scratch using Raspberry Pi devices. In this series, you can follow along my journey building my own dedicated Kubernetes cluster at home, from hardware assembly to cluster setup and management.

A small scale cluster allows you to find learnings in a cost-efficient setup, which can then be applied to real-world scenarios and scale up to larger clusters as needed. While large-scale cluster will introduce additional complexity and scenarios not covered in this guide (for now), we are trying to be “production-ready” by meticulously going through all aspects of security, availability and reliability.

This is by no means intended to be complete as I am not intending to write a manual here (you can always dig deeper into the relevant documentations). Instead this guide reflects all the step taken by me during the setup of my cluster, written in a way so you can follow along, including my thoughts and findings outside the official documentations.

I truly hope this guide is helpful for you and can provide valuable insights for those planning a similar project.

I originally planned to offer this guide as a paid online course, but as a strong believer in free open source resources, I made it available for free instead.

Please, if my guides helped you, I would be very grateful if you could support my work by becoming a GitHub Sponsor and by sharing the guides in your network. 🙏

Eventually I might offer additional guides as paid online courses, but for now, I want to focus on providing free guides.

Thank you! ❤️

Overview

As this series was written as an online course, the guide is structured as a curriculum with sections and lessons. Each lesson is a separate post in this series, and the terms guide, series and course, as well as lesson, article and posts, are used interchangeably.

This series is divided into multiple sections, each focusing on a specific area of the guide. Here's an overview of what you can expect in each section, with links to individual lessons:

Getting Started
