How to install kubernetes

Before we start, please make sure you read the kubernetes-101 first.
This article will not cover installation on Windows system.

Verify virtualization

Before you start, make sure that VT-x/AMD-v virtualization is enabled. Minikube requires it! A simple check can help you figure out if virtualization is already enabled.

Linux

cat /proc/cpuinfo | egrep 'vmx|svm' | wc -l

OS X

sysctl -a | grep machdep.cpu.features | grep VMX | wc -l

If the output number is greater than zero, you all set!

Install a Hypervisor

A hypervisor is a program that would enable you to host virtual machines on a single hardware.

Linux

VirtualBox or kvm

OS X

VirtualBox or hyperkit

Installing kubectl
