What is minikube?
Minikube is a tool that quickly sets up a local Kubernetes cluster on macOS, Linux, and Windows. It can deploy as a VM, a container, or on bare metal.
Minikube is a pared-down version of Kubernetes that gives you all the benefits of Kubernetes with a lot less effort.
This makes it an interesting option for users who are new to containers, and also for projects in the world of edge computing and the Internet of Things
Features of minikube:
Supports the latest Kubernetes release (+6 previous minor versions)
Cross-platform (Linux, macOS, Windows)
Deploy as a VM, a container, or on bare-metal
Multiple container runtimes (CRI-O, containers, docker)
Direct API endpoint for blazing-fast image load and build
Advanced features such as LoadBalancer, filesystem mounts, FeatureGates, and network policy
Addons for easily installed Kubernetes applications
Supports common CI environments
