Bare-metal Kubernetes with K3s Learn how to configure K3s on bare-metal to run a Kubernetes cluster with just as much resilience and fault tolerance as a managed service. This tutorial is a follow-on from my post Kubernetes on bare-metal in 10 minutes from 2017. The original post focused on getting Kubernetes working across a number of bare-metal hosts running Ubuntu, and then it went on to deploy a microservice and the dashboard. It was a primer, and written to help new users kick the tires with Kubernetes. It used production-ready kubeadm, but only used one master node, meaning it couldn't tolerate a failure.
