+How to Install MiniKube on RHEL 8/Rocky Linux 8/AlmaLinux 8
+======
+
+In this post, we will cover how to install minikube on RHEL 8, Rocky Linux 8 or AlmaLinux 8 step by step.
+
+Minikubeis a cross-platform and open-source tool that makes it possible for you to deploy a single-node Kubernetes cluster on your local machine.
+
+Kubernetes, also known as k8sor simply as Kube, is an open-source container orchestration platform used for the automation scaling and deployment of containers.Minikube cluster helps developers and admins to build their test environment in minikube cluster.
+
+##### Prerequisites of MiniKube
+
+- Minimal Installed RHEL 8 or Rocky Linux 8 or AlmaLinux 8
+- Locally Configured Repo or Subscription for RHEL 8.
+- Minimum of 2 GB RAM and 2 vCPUs
+- 20 GB hard disk space
+- Sudo User with admin
+- A stable internet connection
+- Docker or virtual machine manager like VirtualBox, KVM,and VMware etc.
+
+In this post, we will be using docker as driver for minikube. 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. You are welcome to share your feedback and comments in below comments section.
