Minikube – a utility to run a Kubernetes cluster locally on your PC.
It can use Virtualbox, VMware, Hyper-V etc hypervisors which will be used to create a virtual machine with a Kubernetes cluster.
Minikube is a great tool for developers or DevOps engineers to test deployments/services etc without the need to create and conigure a real cluster.
In the post below – a quick HowTo install it and run a Kubernetes pod using the Minikube.
In Arch Linux can be installed from AUR:
$ yaourt -S minikube
If you haven’t Virtualbox yet – install it, here it will be used for Minikube:
$ sudo pacman -S virtualbox
minikube will work with Kubernetes via kubectl – install it as well:
$ yaourt -S kubectl
Now check it.
Start Minikube itself:
$ minikube start

Check Virtualbox VMs running:
$ VBoxManage list runningvms
"minikube" {37da5f2d-c486-4419-a152-eb5dcedde6f3}
Create a new pod:
$ kubectl run hello-minikube --image=gcr.io/google_containers/echoserver:1.4 --port=8080
kubectl run --generator=deployment/apps.v1 is DEPRECATED and will be removed in a future version. Use kubectl run --generator=run-pod/v1 or kubectl create instead.
deployment.apps/hello-minikube created
Run the service:
$ kubectl expose deployment hello-minikube --type=NodePort
service "hello-minikube" exposed
List pods:
$ kubectl get pod
NAME READY STATUS RESTARTS AGE
hello-minikube-5857d96c67-x46nk 1/1 Running 0 74s
And check the service itself:
$ curl $(minikube service hello-minikube --url)

After you’ll finish – stop and delete VMs, pods, and services:
$ minikube stop
[✋] Stopping "minikube" in virtualbox ...
[🛑] "minikube" stopped.
Done.

Well done... I prefer to run the minikube with Podman engine, kinda full open source solution and get up faster than with VB.
