MiniKube as Docker Desktop replacement

Important

This step is not executed as part of the tutorial it's only a reciepes how to replace Docker for Desktop

Minikube is local Kubernetes, focusing on making it easy to learn and develop for Kubernetes.

All you need is Docker (or similarly compatible) container or a Virtual Machine environment

  • Well documented
  • Can use many container Runtime (get rid of Docker !)

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

Install Docker CLI

brew install docker

Install Minikube

OsX Install
curl -LO https://storage.googleapis.com/minikube/releases/latest/minikube-darwin-amd64
sudo install minikube-darwin-amd64 /usr/local/bin/minikube
Linux Install
curl -LO https://storage.googleapis.com/minikube/releases/latest/minikube-linux-amd64
sudo install minikube-linux-amd64 /usr/local/bin/minikube
Windows Install
New-Item -Path 'c:\' -Name 'minikube' -ItemType Directory -Force
Invoke-WebRequest -OutFile 'c:\minikube\minikube.exe' -Uri 'https://github.com/kubernetes/minikube/releases/latest/download/minikube-windows-amd64.exe' -UseBasicParsing

Install Matrix

Refer to the Installation Matrix to get the right command, like installing on Arm64 CPU.

Start Docker with HyperKit (https://minikube.sigs.k8s.io/docs/drivers/hyperkit/)

minikube start --driver hyperkit # will be auto-detected

Point Docker CLI to Docker Engine inside Minikube VM

minikube docker-env
eval $(minikube docker-env)

Show Cluster info

kubectl cluster-info

  • All k8s contexts

We can check the current Kubernetes context using kubectl:

k config  get-contexts
