Kubernetes: running Minikube on Arch Linux

Minikube — a utility to run a Kubernetes cluster locally on your PC.

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.

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

🏄 Done! Thank you for using minikube!

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)
CLIENT VALUES:
client_address=172.17.0.1
command=GET
real path=/
query=nil
request_version=1.1
request_uri=http://192.168.99.100:8080/
SERVER VALUES:
server_version=nginx: 1.10.0 — lua: 10001
HEADERS RECEIVED:
accept=*/*
host=192.168.99.100:31345
user-agent=curl/7.64.0
BODY:
-no body in request-

After you’ll finish — stop and delete VMs, pods, and services:

$ minikube stop
✋ Stopping “minikube” in virtualbox …
🛑 “minikube” stopped.

Done.
