Kubernetes: running Minikube on Arch Linux

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 configure 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:

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)
