A crude runbook for creating mini k8s clusters for homelab’ing and such.

• Prerequisites
  • A Ubuntu machine for kubeadm
  • Ubuntu machine(s) for kubernetes workers
  • unzip installed

Typically what I do is provision Ubuntu VMs on vSphere or locally with VMware Fusion, any Ubuntu VM should work.

On all machines (master and workers)

• SSH into your machine
• Get scripts from github

curl -L -O https://github.com/corbtastik/kubeadm-bake/archive/refs/heads/main.zip
unzip main.zip
cd kubeadm-bake-main

• Edit install.env to your liking. CONTROL_PLANE_ENDPOINT is the name in DNS or IP for the kubeadm/master machine.

CONTAINERD_VERSION=1.2.13-2
DOCKER_VERSION=5:19.03.11~3-0~ubuntu
KUBE_VERSION=1.19.8-00
KUBE_NAME=kubeadm
CONTROL_PLANE_ENDPOINT=kubeadm.retro.io

On master machine

• Edit install.env to your liking
• Run install_master.sh to provision kubeadm and k8s master

On worker machines

• Edit install.env to your liking
• Run install_worker.sh to provision a worker node
