Overview

Minikube is a tool that installs Kubernetes locally. Minikube runs a single-node Kubernetes cluster inside a VM on the local development machine. To install it, it requires virtualization extensions enabled in your system's BIOS.

Installation

Latest Version

https://github.com/kubernetes/minikube/tags

Mac

https://minikube.sigs.k8s.io/docs/start/

brew install minikube

The installation will automatically add a "minikube" context.

Uninstallation

brew uninstall minikube

Note that uninstallation does not clean the context.

Linux
