How to install Minikube on CentOS 7 and 8

In this tutorial, we will learn How to install Minikube on CentOS 7 and 8. Minikube is free software that lets you set up a small Kubernetes cluster with a single computer. The software starts up a virtual machine and runs a Kubernetes cluster inside of it. This lets you test directly in a Kubernetes environment.

Prerequisites​

  • A normal user with SUDO privileges or Super user
  • Yum repositories configured to install packages in your CentOS server.

Steps to install Minikube on Centos​

Step 1: Update your machine

yum -y update

Step 2: Install EPEL repositories using below command.

 yum -y install epel-release

Step 3: Install libvirt packages, dependencies to run Minikube

yum -y install libvirt qemu-kvm virt-install virt-top libguestfs-tools bridge-utils

Step 4: Now run, enable and check the status of libvirt daemon to ensure it is running and installed successfully.

systemctl enable --now libvirtd
systemctl status libvirtd

Step 5: Now, add your any normal user to libvirt group by using usermod command.

usermod -a -G libvirt <normal-username>
usermod -a -G libvirt prabhu      # my normal user

Step 6: Now, append the below mentioned details to the below file.

vi /etc/libvirt/libvirtd.conf

Append contend to above file::

unix_sock_group = "libvirt"

unix_sock_rw_perms = "0770"

Step 7: Restart the libvirtd daemon/ service to reflcet the changes.

systemctl restart libvirtd.service

Download Minikube binary​

Step 8: Download and install the minikube binary using the curl and install command as shown below.

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

Step 9: Check the version installed of your minikube.

Download Kubectl binary and installed it​

Step 10: Download the latest kubectl binary using the below command

curl -LO https://storage.googleapis.com/kubernetes-release/release/`curl -s https://storage.googleapis.com/kubernetes-release/release/stable.txt`/bin/linux/amd64/kubectl

Step 11: Now, make the binary executable, so the it can be run

chmod +x kubectl

Step 12: Move the binary to /usr/loca/bin directory so that it can be run from anywhere of your machine.

mv kubectl /usr/local/bin

Step 13: Check the version installed on your centos machine

kubectl version --client -o json

Version of installed kubectl

Install Docker container​

Step 14: Now, without, docker environment, you cannot run minikube. Therefore, run the below command to add the repolist to your machine to install Docker.

 yum install -y yum-utils
 yum-config-manager --add-repo https://download.docker.com/linux/centos/docker-ce.repo

Step 15: Install the docker related dependencies to run your minikube.

yum install docker-ce docker-ce-cli containerd.io docker-buildx-plugin docker-compose-plugin

Step 16: Now, run the below command to enable and start the docker service instantly

systemctl enable --now docker

Step 17: Check the docker running version.

docker version

Docker installed on Centos

Step 18: Now, add your normal user( user which is added to libvirt group in earlier step) to the docker group as well.

usermod -aG docker prabhu

Step 19: Now, switch to that user and run the minikube with driver docker as a default driver.

su - prabhu 
minikube start --driver=docker
