How to Install Minikube on CentOS 7

How to Install Minikube on CentOS 7

Minikube is an open-source tool that enables you to run and manage Kubernetes clusters on your local machine. If you're looking to test Kubernetes deployments, you can easily set up a local Kubernetes cluster with Minikube on CentOS 7.

In this tutorial, we will guide you through the process of installing Minikube on CentOS 7 step-by-step.

Let's get started.


Before you begin, you need to make sure that you have the following prerequisites in place:

  • A CentOS 7 server with sudo privileges
  • A terminal or command-line interface

Step 1: Install KVM

Minikube requires a hypervisor to run on your machine. KVM (Kernel-based Virtual Machine) is a popular hypervisor that works well with Minikube.

To install KVM, run the following commands:

sudo yum install epel-release -y
sudo yum install qemu-kvm libvirt libvirt-python libguestfs-tools virt-install -y
sudo systemctl start libvirtd
sudo systemctl enable libvirtd
sudo systemctl status libvirtd

Step 2: Install kubectl

kubectl is a command-line tool for managing Kubernetes clusters. You will need to install kubectl to interact with your Minikube cluster.

To install kubectl, run the following command:

sudo yum install kubernetes-client -y

Step 3: Install Minikube

To install Minikube, run the following command:

curl -LO https://storage.googleapis.com/minikube/releases/latest/minikube-linux-amd64
sudo install minikube-linux-amd64 /usr

Step 4: Start Minikube

To start Minikube, run the following command:

minikube start --vm-driver=kvm2

This command will download and install the required Kubernetes components and start a local Kubernetes cluster using KVM as the hypervisor.

Step 5: Verify the Installation

To verify that Minikube is installed correctly, run the following command:

kubectl version

If everything is installed correctly, you should see the version information for both the client and server components.

Step 6: Deploy an Application

Now that your Minikube cluster is up and running, you can deploy a sample application to test it.

Create a file named hello-minikube.yaml with the following contents:

apiVersion: apps/v1
kind: Deployment
name: hello-minikube
app: hello-minikube
replicas: 1
app: hello-minikube
- name: hello-minikube
image: k8s.gcr.io/echoserver:1.4
- containerPort: 8080

Then, run the following command to deploy the application:

kubectl apply -f hello-minikube.yaml

Step 7: Verify the Application

To verify that the application is deployed and running correctly, run the following command:

kubectl get pods

You should see a pod named hello-minikube with a status of Running.

Step 8: Access the Application

To access the application, run the following command to get the URL:

minikube service hello-minikube --url

Copy the URL and paste it into your web browser. You should see a message that says "Echo server is running".
