How to Install Minikube on CentOS 7

Minikube is a powerful tool that allows developers to run Kubernetes clusters locally for testing and development purposes. If you're working on CentOS 7 and want to set up Minikube, you're in the right place. In this guide, we'll walk you through the step-by-step process of installing Minikube on CentOS 7.

Step 1: Prerequisites

Before we dive into the installation process, make sure your CentOS 7 system meets the following prerequisites:

  • A CentOS 7 machine with internet access.
  • A user account with sudo privileges.

Step 2: Update System Packages

It's always a good practice to ensure that your system packages are up-to-date. Open a terminal and run the following commands:

sudo yum update

Step 3: Install Hypervisor (Optional)

Minikube requires a hypervisor to create virtual machines. While it's optional, using a hypervisor such as VirtualBox or KVM is recommended. Install your preferred hypervisor using the following commands:

For VirtualBox:

sudo yum install VirtualBox

For KVM:

sudo yum install @virt

Step 4: Install kubectl

Minikube also requires kubectl, the command-line tool for interacting with Kubernetes clusters. Install it with the following command:

sudo yum install kubectl

Step 5: Install Minikube

Now, let's install Minikube. Open a terminal and run the following commands:

curl -LO
sudo rpm -Uvh minikube-latest.x86_64.rpm

Step 6: Start Minikube Cluster

With Minikube installed, you can start a Kubernetes cluster by running:

minikube start

This command will download the necessary ISO and set up a single-node Kubernetes cluster on your CentOS 7 machine.

Step 7: Verify Minikube Installation

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

minikube status

This command will display the status of your Minikube cluster.

Step 8: Interact with Minikube Cluster

Now that Minikube is up and running, you can interact with the Kubernetes cluster using kubectl. For example, check the nodes in your cluster:

kubectl get nodes

Step 9: Stop and Delete Minikube Cluster

To stop and delete the Minikube cluster, use the following command:

minikube stop && minikube delete

Congratulations! You've successfully installed Minikube on CentOS 7 and created a local Kubernetes cluster for your development and testing needs.
