With all the prerequisites met, it’s time now to roll up our sleeves and get our hands dirty. + +### Step 1) Enable Official Docker Repository + +To enable docker official repository run, + +``` +$ sudo dnf config-manager --add-repo=https://download.docker.com/linux/centos/docker-ce.repo +$ sudo dnf repolist +``` + +### Step 2) Install Docker CE (Community Edition) + +Run the following dnf command to install docker and its dependencies, + +``` +$ sudo dnf install docker-ce docker-ce-cli containerd.io -y +``` + +output, + +Once docker is installed the start and enable it’s service, run following systemctl commands, + +``` +$ sudo systemctl start docker +$ sudo systemctl start docker +``` + +Allow your local user to run docker commands without sudo, run + +``` +$ sudo usermod -aG docker $USER +$ newgrp docker +``` + +### Step 3) Install Kubectl Binary + +Kubectl is a command-line tool which interacts with Kubernetes cluster via APIs. Using kubectl we deploy our applications as deployment. By default, kubectl is not included in RHEL 8 , Rocky Linux 8 or AlmaLinux 8 package repositories. Therefore, we are going to manually install it using beneath commands, + +``` +$ curl -LO "https://dl.k8s.io/release/$(curl -L -s https://dl.k8s.io/release/stable.txt)/bin/linux/amd64/kubectl" +$ sudo cp kubectl /usr/local/bin/ && sudo chmod +x /usr/local/bin/kubectl +$ kubectl version --client +``` + +Output of above commands would be something like below, + +### Step 4) Download MiniKube Binary and Start Cluster + +After installing the kubectl, let’s download and install minikube binary using the following commands, + +``` +$ curl -LO https://storage.googleapis.com/minikube/releases/latest/minikube-linux-amd64 +$ sudo install minikube-linux-amd64 /usr/local/bin/minikube +``` + +Now start minikube cluster using the beneath command, + +``` +$ minikube start --driver docker +``` + +Output above confirms that minikube command has started the single node Kubernetes cluster using docker as driver. + +Run below minikube command to verify the status of your local Kubernetes cluster, + +``` +[[email protected] ~]$ minikube status +minikube +type: Control Plane +host: Running +kubelet: Running +apiserver: Running +kubeconfig: Configured +[[email protected] ~]$ +[[email protected] ~]$ minikube ip +192.168.49.2 +[[email protected] ~]$ +``` + +To stop stop the minikube cluster, execute, + +``` +$ minikube stop +``` + +Execute the “kubectl” commands to view cluster and node information + +``` +$ kubectl cluster-info +$ kubectl get nodes +``` + +### Step 5) Test and Verify Kubernetes Cluster + +To test Kubernetes cluster, let try to create k8s deployment using echo server image, it is equivalent to http web server and expose it as a service on port 8080, + +``` +[[email protected] ~]$ kubectl create deployment test-minikube --image=k8s.gcr.io/echoserver:1.10 +deployment.apps/test-minikube created +[[email protected] ~]$ +``` + +To access test-minikube deployment, expose it as service, run the following command, + +``` +[[email protected] ~]$ kubectl expose deployment test-minikube --type=NodePort --port=8080 +service/test-minikube exposed +[[email protected] ~]$ +``` + +Run below kubectl command to get deployment,pods and service  information for above created deployment, + +``` +$ kubectl get deployment,pods,svc +``` + +To access service, get its url by running the beneath command. + +``` +[[email protected] ~]$ minikube service test-minikube --url +http://192.168.49.2:32291 +[[email protected] ~]$ +[[email protected] ~]$ curl http://192.168.49.2:32291/ +``` + +Great, it means our Kubernetes cluster is working fine as we are able to access our sample application. + +##### Step 6) Enable MiniKube Addons + +Minikube offers addons which can add additional functionality to our clusters. To list all available addons run, + +``` +$ minikube addons list +``` + +Kubernetes ships with a dashboard that allows you to manage your cluster. In Minikube, dashboard has been added as an addons. So to enable it, run + +``` +$ minikube addons enable dashboard +``` + +Also to enable nginx ingress controller, run + +``` +$ minikube addons enable ingress +``` + +To access the dashboard, run + +``` +$ minikube dashbaord --url +``` + +This will start the dashboard in your systems’s web vrowser. + +And that’s just about it. We have managed to successfully install Kubernetes with Minikube on RHEL 8, Rocky Linux 8 or AlmaLinux 8.
