Installing minikube on CentOS

In this blog post, I’ll show you how to install Minikube on CentOS. Minikube is a platform you can use to test kubernetes clusters on your local machine or in a virtual machine.

Let’s start off with a fresh Install of CentoOS 7 on a virtual machine using a minimal install. If you need some help getting a Linux VM us, check out my Pluralsight course here to help you with that. You will want to ensure this virtual machine has the resource you want to run the container/pods scenarios you’d like to worth with. My configuration is dual vCPU with 10GB of RAM. 

Since we’re running a hypervisor inside a VM, you will need to enable nested virtualization in your virtual machine configuration. Cloud friends, this will not apply to you as most cloud providers do not have this enabled. 

Let’s get started with some prerequisites!

SSH into your virtual machine. I don’t have DNS internally…so I am using the IP address of the virtual machine

demo:~ aen$ ssh aen@

First, install a hypervisor on CentOS, I’m going to use KVM. Installing KVM on RHEL based Linux distributions is most easily done by using a yum group install. This will install all of the packages included in that group for you in one command. Minikube will run inside your virtual machine as a KVM virtual machine. Minikube can use other hypervisors such as Virtual Box and VMware Fusion/Workstation.

sudo yum group install “Virtualization Host”

Once the installation is complete, confirm the KVM kernel module is loaded by listing the running kernel modules with lsmod then grepping for the string kvm.

lsmod | grep kvm

kvm_intel             183720  0 

kvm                   578558  1 kvm_intel

irqbypass              13503  1 kvm

Next we’ll install the KVM2 Driver Plugin for minikube

curl -Lo docker-machine-driver-kvm2 \

 && chmod +x docker-machine-driver-kvm2 \

 && sudo cp docker-machine-driver-kvm2 /usr/local/bin/ \

 && rm docker-machine-driver-kvm2

Now, that we have the prep work out of the way, let’s install kubectl. This is the command line utility you will use to interact with your Kubernetes cluster.

sudo yum install kubernetes-client

Next we’ll Install Minikube on our VM

sudo curl -Lo minikube \

 && chmod +x minikube \

 && sudo cp minikube /usr/local/bin/ \

 && rm minikube

With everything installed, let’s launch minikube – this will download the Minicube ISO, which is a virtual machine containing the minikube cluster.

[aen@k8s1 ~]$ minikube start –vm-driver kvm2

Kubectl is now configured to use the cluster.

Finally lets check on your cluster configuration to ensure everything is online.

[aen@k8s1 ~]$ kubectl cluster-info

CoreDNS is running at


To further debug and diagnose cluster problems, use ‘kubectl cluster-info dump’.

With that, you have a functioning Kubernetes cluster inside your virtual machine which you can use for testing and development of your Kubernetes based solutions.
