 To setup Raspberry PI for Kubernetes In order to setup the Raspberry PI to run Kubernetes, you need to assemble it and install the OS and do some minor adjustments. But first of all, let's check the requirements. Requirements For this lab we'll require to use: 2 Raspberry boxes, at least (se below for information about), and your computer A Micro SD card reader for your computer, if it hasn't already  Devices such as mouse, keyboard and monitor (or TV) Raspberry box content To ensemble the two Raspberry boxes, you should have the following: Two (or more) Raspberry PI 4B board with 4GB RAM (recommended). The 2GB RAM will work for the nodes, not for the master. I have one board of 2GB RAM and another of 8GB RAM, but with 4GB for the master is fine.  Two Raspberry PI cases for Raspberry PI 4B, with fan and heat dissipation. Some cases provides power cable, so it's up to you if you buy this with power or you buy the power cable apart.   Two Power cables ...

How to install Kubernetes cluster on Raspberry PI Kubernetes Kubernetes , as it's self defined, is an open-source system for automating deployment, scaling, and management of containerized applications. Event though it has been used for orchestration (optional) nowadays is required by several applications as requirement. In this lab, we'll use microk8s , which is a powerful, lightweight, reliable production-ready Kubernetes distribution and which requires a small amount of memory and disk. So it's perfect for us. Raspberry PI Raspberry PI in the other hand are small single-board computers, which allow us to use their own Debian fork, or other OS, like Ubuntu. In this lab we'll use the latest Ubuntu Desktop 64bit. On this lab we'll use the Raspberry PI 4B, and even when it's possible to use the 2GB RAM option, I totally recommend to use the 4GB RAM.
