## AI overview

A video tutorial shows how to build a multi-architecture Kubernetes cluster by adding an ARM-based Raspberry Pi 4 running Ubuntu and k3s to an existing x86 cluster. It also discusses CPU-specific Docker images and configuration requirements.

## Source excerpt

Building a Multi-architecture CPU Kubernetes cluster is easier than you think with k3s.In this video we'll build a Raspberry Pi 4 with an ARM CPU and add it to our existing x86 x64 amd64 CPU Kubernetes cluster.Our foundation will be Ubuntu for ARM, then we'll add k3s, and then join it to our cluster.We'll also discuss how this works with Docker images built for specific CPU types.We'll also tal...
