Cluster

In my previous article we took a look at how to bootstrap K3s with Cilium starting from a fresh Debian 12 network installation. Having recently started to play around with Proxmox Virtual Environment, I feel the natural progression is to get to know OpenTofu/ Terraform and Cloud-init to automatically provision virtual machines for a Kubernetes cluster.

Getting started with Kubernetes might seem like a daunting task at first, but getting a basic ephemeral cluster up and running with tools like minikube, kind, or k3d is quite straightforward if you follow their documentation. In this article we’ll explore how to bootstrap a more permanent, or production grade, Kubernetes cluster using k3s.
