K3s Lightweight Kubernetes on Ubuntu 24.04 LTS

A full CNCF-certified Kubernetes cluster in a single VM. K3s bundles the control plane, kubelet, containerd, and Traefik ingress into one lightweight binary — ideal for edge workloads, CI, and teams that want Kubernetes without cluster-management overhead.

Pay-as-you-go pricing: $0.09 per vCPU per hour software fee, plus Azure infrastructure (billed by Microsoft). Example: a 4-vCPU VM runs about $263/month in software fees at 730 hours — stop the VM, stop paying.

What's included

  • K3s v1.31 — CNCF-certified Kubernetes distribution
  • Traefik ingress and local-path storage provisioner included
  • containerd runtime, no Docker daemon required
  • Ubuntu 24.04 LTS with automatic security updates
  • Trusted Launch: Secure Boot + vTPM supported
  • Add agent nodes later to grow into a multi-node cluster

Quick start

  1. SSH into the VM with the username and key you chose at deploy.
  2. K3s is running as a systemd service; verify with `sudo kubectl get nodes`.
  3. Copy `/etc/rancher/k3s/k3s.yaml` (rewrite the server IP) to use kubectl from your workstation, and deploy workloads with kubectl or Helm.

Common use cases

  • Edge and branch-office Kubernetes
  • CI/CD test clusters that boot in minutes
  • Learning and certification practice (CKA/CKAD)
  • Lightweight production for containerized apps
