What you’ll need 📃

In this blog we can see, How to run Minikube using Docker.

Requirements: ⬇️

  • Install Docker-engine

Note: Minikube run as ordinary user not root.

Step 1: Set Up Docker Environment 1️⃣

sudo yum remove -y docker \
                  docker-client \
                  docker-client-latest \
                  docker-common \
                  docker-latest \
                  docker-latest-logrotate \
                  docker-logrotate \
                  docker-engine

Set-up Repo:

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

Install and start Docker Engine:

  • Use docker 18.09 or higher (20.10 or higher is recommended)
#Install Docker.io
sudo yum install docker-ce docker-ce-cli containerd.io docker-buildx-plugin docker-compose-plugin

# Start and Enable docker at boot
sudo systemctl enable docker && sudo systemctl start docker

Step 2: Installing Minikube 2️⃣

#Download Minikube 
wget https://storage.googleapis.com/minikube/releases/latest/minikube-linux-amd64

#Provide Exeute permission
chmod +x minikube-linux-amd64

#Make as internal command
sudo mv minikube-linux-amd64 /bin/minikube

#check minikube version
minikube version

Step 3: Start Minikube 3️⃣

Run the below command to start Minikube.

Note: Minikube initialization it will sometime, please wait and don’t interrupt

minikube start - driver=docker

Step 4: Set kubectl command 4️⃣

minikube kubectl -- get pods -A

Let’s make a change.

alias kubectl='minikube kubectl --'
alias k='minikube kubectl --'

#Set up in bashrc for permanent 
echo "alias kubectl='minikube kubectl --'"   >> ~/.bashrc
echo "alias k='minikube kubectl --'" >> ~/.bashrc

Set docker driver as default 🤝

To set a docker driver default, run the below commands.

minikube config set driver docker
