Steps to install Kubernetes Cluster with minikube

You must be asking a question "How do I setup Kubernetes Cluster?" and you may end up getting different answers from different search results and it can be overwhelming for beginners. Kubernetes is a sophisticated system, and getting it installed and managing it well isn't an easy task.

However, as the Kubernetes community has expanded and matured, more and more user-friendly tools have emerged. As of today, based on your requirements, there are a lot of options to choose from:

  • If you are using physical (bare-metal) servers or virtual machines (VMs), Kubeadm is a good fit.
  • If you're running on cloud environments, kops and Kubespray can ease Kubernetes installation, as well as integration with the cloud providers.
  • If you want to drop the burden of managing the Kubernetes control plane, almost all cloud providers have their Kubernetes managed services, such as Google Kubernetes Engine (GKE), Amazon Elastic Kubernetes Service (EKS), Azure Kubernetes Service (AKS), and IBM Kubernetes Service (IKS).
  • If you just want a playground to study Kubernetes , Minikube and Kind can help you spin up a Kubernetes cluster in minutes.


So, as you see you have a bunch of options to choose from to deploy your first Kubernetes Cluster. In this Kubernetes Tutorial I will cover the steps to install kubernetes cluster on CentOS 8 using Minikube.


Overview on Minikube

Minikube is a tool that can be used to set up a single-node cluster, and it provides handy commands and parameters to configure the cluster. It primarily aims to provide a local testing environment. It packs a VM containing all the core components of Kubernetes that get installed onto your host machine, all at once. This allows it to support any operating system, as long as there is a virtualization tool (also known as a Hypervisor) pre-installed.


Minikube Architecture

As we learned in our previous tutorial, a Kubernetes cluster consists of a controller and worker node where both node types have their own set of components. But since Minikube is a single node cluster, it will contain all the cluster components inside this single node, which would look something like following:

The minimum resource requirement for your physical host:

  • 2 CPUs or more
  • Minimum 2GB of free memory
  • Minimum 20GB of free disk space

Additionally your host must have:

  • Working internet connection
  • Virtualization technology must be enabled in BIOS to support hypervisor
  • Anyone of the supported hypervisor

The following are the most common Hypervisors supported by Minikube:

  • VirtualBox (works for all operating systems)
  • KVM (Linux-specific)
  • Hyperkit (macOS-specific)
  • Hyper-V (Windows-specific)


Lab Environment

I will use my Laptop which is installed with Windows 10 and Oracle VirtualBox to setup Minikube.


Install Oracle VirtualBox

You may also choose to install different hypervisor based on your environment, we will use Oracle VirtualBox as I already use this for writing most of my tutorials.

Download VirtualBox software from their official repository. I have written another article to install Oracle Virtual Box, which is quiet straight forward on Windows. Just double click the downloaded software and follow the instructions, leave all the settings to default.


Download and install kubectl

The Kubernetes command-line tool, kubectl, allows you to run commands against Kubernetes clusters. You can use kubectl to deploy applications, inspect and manage cluster resources, and view logs.

  • If you are using a different platform other than Windows then you can follow official guide to download the kubectl for your platform
  • I have created a folder inside my C drive "C:\Kubernetes" where I will be storing these software.
  • As the time of writing this tutorial, kubectl 1.19 was the latest stable release available at this link.
  • Or if you have curl installed, use this command:
curl -LO
C:\Kubernetes>kubectl version --client

Output from my setup:

Download and install Minikube

  • You can follow the official guide to get the latest available minikube package for your respective platform. For Windows you can download the latest available minikube from
  • I have downloaded minikube and placed it inside C:\Kubernetes folder which I created in the previous step.
  • Next you can double click on the downloaded installer and just follow the on screen instructions to install the software.
  • Once installed, open a command prompt and enter "minikube version" to make sure it is working as expected.

Build and start your minikube cluster

Next we will deploy our Kubernetes Cluster for which we will execute "minikube start". This command will download the minikube ISO image and deploy a new Virtual Machine using Oracle VirtualBox which will take some time depending upon your network speed.

You don't need to create any VM, this step itself will create and deploy a new VM on Oracle VirtualBox. Moving forward after you shutdown your VM, you should again use minikube start to start the cluster services before you can access it.

minikube has successfully deployed our single node cluster, you can verify the same on your Oracle VirtualBox where you should have a new VM in running state.

Interact with your cluster

The following commands should help establish that the Kubernetes cluster that was started by Minikube is running properly.

C:\Kubernetes>minikube status
type: Control Plane
host: Running
kubelet: Running
apiserver: Running
kubeconfig: Configured

Now, let's look at the version of the kubectl client and Kubernetes server:

C:\Kubernetes>kubectl version --short
Client Version: v1.19.0
Server Version: v1.19.2

To check the machines comprise the cluster and get some basic information about them:

C:\Kubernetes>kubectl get node
minikube   Ready    master   112m   v1.19.2

Now you should have Minikube set up with a single-node Kubernetes cluster.


Deploy applications

Now that our cluster node is UP and running, we can create our first Pod (which is basically a container), but before that verify if there is already any pod available on the minikube cluster:

C:\Kubernetes>kubectl get pods
No resources found in default namespace.

Since the cluster is freshly installed, we did not had any pods. I will create a new pod "hello-minikube"

C:\Kubernetes>kubectl create deployment hello-minikube
pod/hello-minikube created

Now verify the available pods, currently the status shows as "ContainerCreating"

C:\Kubernetes>kubectl get pods
NAME                              READY   STATUS              RESTARTS   AGE
hello-minikube-6ddfcc9757-gtr9s   1/1     ContainerCreating   1          19h

Wait for sometime and execute the same command, now the status of the pod shows as running:

C:\Kubernetes>kubectl get pods
NAME                              READY   STATUS    RESTARTS   AGE
hello-minikube-6ddfcc9757-gtr9s   1/1     Running   1          3m2s

This is basically a webserver and to be able to access it we need to execute following command:

C:\Kubernetes>kubectl expose deployment hello-minikube --type=NodePort --port=8080
service/hello-minikube exposed

To get the URL of the web server

C:\Kubernetes>minikube service hello-minikube --url

Now we can use this URL to access our application

We are done with this demonstration so I will delete the deployment

C:\Kubernetes>kubectl delete deployment hello-minikube
deployment.apps "hello-minikube" deleted

Now we don't have any more pods running:

C:\Kubernetes>kubectl get pods
No resources found in default namespace.


Manage your cluster

To pause Kubernetes without impacting deployed applications use:

minikube pause

Lastly I will stop my minikube cluster which will power off the virtual machine:

C:\Kubernetes>minikube stop
* Stopping node "minikube"  ...
* 1 nodes stopped.

To delete all the minikube clusters

minikube delete --all



Minikube is mostly used to setup (Proof-of-Concept) POC environment to learn Kubernetes Cluster. Although I would be using kubeadm to setup multi-node Kubernetes Cluster in my next article which I will use to demonstrate the entire Kubernetes Tutorial. In this article, you learned the steps to deploy a cluster using minikube on your WIndows host machine, similarly you can deploy cluster on any other host environment such as Ubuntu, CentOS etc.
