MOK - Run Kubernetes on your laptop

Current kubernetes version: 1.31

Requirements

• Fedora 40
• Podman or Docker
• 5 GB of free disk space

Install

On Fedora ~/local/bin should be in your $PATH. Copy mok to that location:

curl --output-dir ~/.local/bin -O https://github.com/bashtools/mok/blob/master/package/mok
chmod +x ~/.local/bin/mok

First use

# Takes around 10 minutes
sudo mok build image

Create a multi node kuberenetes cluster

sudo mok create cluster myk8s --masters 1 --workers 1

Run some kubectl commands

export KUBECONFIG=/var/tmp/admin-myk8s.conf
kubectl get nodes
kubectl get pods --all-namespaces

# --privileged is required if you want to `ping`
kubectl run --privileged --rm -ti alpine --image alpine /bin/sh

Get help

sudo mok -h
sudo mok create -h

Delete the cluster

sudo mok delete cluster myk8s

Uninstall mok completely

rm ~/.local/bin/mok

Then delete the podman/docker images that were built by mok build.

Known Issues

• With multiple master nodes only the first master is set up

Some Features

• Builds kubernetes master and worker nodes in containers

• Very simple to use without need for YAML files

• After creating the image a single node cluster builds in under 60 seconds

• For multi-node clusters the 'create cluster' command returns only when kubernetes is completely ready, with all nodes and pods up and ready.

• Can skip setting up kubernetes on the master and/or worker node (good for learning!)

  • In this case the set-up scripts are placed in /root in the containers and can be run by hand
  • Can do kubernetes the hard way (see kthwic)

• mok build and mok create can show extensive logs with --tailf
