Download and install VirtualBox.
Download the CoreOS ISO
Create a new VM in VirtualBox
- For the OS, Other Linux, 64-bit should be fine
- Give the VM 1gb of memory, like your physical hardware has.
- Create a disk of whatever size you want. I made a VMDK file that could expand dynamically up to 8gb.
Mount the ISO in the VM
- Right click on the VM and click settings
Go to the storage tab

kubeadm cloudinit

Setup a single node Kubernetes cluster for development using kubeadm: https://kubernetes.io/docs/setup/independent/install-kubeadm/

Create a CentOS 7 or Ubuntu Xenial (16.04) machine, and run kubeadm.sh as root.

You can pass this script as user-data to cloud-init so that it will be automatically run. For example, on openstack:

openstack server create NAME --flavor FLAVOR --key-name KEY --image 'Ubuntu Xenial' --network NET --security-group SECGROUP --user-data kubeadm.sh

	#!/bin/bash
	sudo vmware-modconfig --console --install-all

	echo "signing vmmon module"
	sudo /usr/src/linux-headers-`uname -r`/scripts/sign-file sha256 ./MOK.priv ./MOK.der $(modinfo -n vmmon)

	echo "signing vmnet module"
	sudo /usr/src/linux-headers-`uname -r`/scripts/sign-file sha256 ./MOK.priv ./MOK.der $(modinfo -n vmnet)

	echo "importing MOK cert"

	sudo: required

	language: ruby

	services:
	- docker

	before_install:
	- echo "Testing Docker Hub credentials"
	- docker login -e=$DOCKER_EMAIL -u=$DOCKER_USERNAME -p=$DOCKER_PASSWORD

	[includeIf "gitdir:~/workspace/work/"]
	path = .gitconfig-work
	[includeIf "gitdir:~/workspace/personal/"]
	path = .gitconfig-personal

	private <T> T factory(Class<T> clazz ){
	try {
	return clazz.newInstance();
	} catch (InstantiationException e) {
	e.printStackTrace();
	} catch (IllegalAccessException e) {
	e.printStackTrace();
	}
