How to Install Minikube on Ubuntu 20.04

Minikube is a tool that makes it easy to run Kubernetes locally. It runs a single-node Kubernetes cluster inside a virtual machine on your computer, allowing you to develop and test your Kubernetes applications without needing a full-blown Kubernetes cluster. In this article, we will guide you through the process of installing Minikube on Ubuntu 20.04.


Before starting the installation process, you must have the following prerequisites:

  • A system running Ubuntu 20.04
  • A user account with sudo privileges
  • VirtualBox installed on your system

Step 1: Install curl and kubectl

Before installing Minikube, you need to install curl and kubectl. You can do this by running the following commands:

sudo apt update
sudo apt install curl
curl -LO "$(curl -L -s"
sudo install -o root -g root -m 0755 kubectl /usr/local/bin/kubectl
kubectl version --client

Step 2: Install Minikube

Once you have installed curl and kubectl, you can install Minikube by running the following commands:

curl -LO
sudo install minikube-linux-amd64 /usr

Step 3: Start Minikube

To start Minikube, run the following command:

minikube start

This will download the necessary ISO file and start a virtual machine with a Kubernetes cluster running inside it. The first time you run this command, it may take a few minutes to complete.

Step 4: Verify Installation

To verify that Minikube is installed and running correctly, you can run the following command:

kubectl get nodes

This command should output information about the Minikube node that is running.

Step 5: Deploy an Application

Now that you have Minikube up and running, you can deploy a sample application to test it out. Here's an example deployment YAML file that you can use:

apiVersion: apps/v1
kind: Deployment
name: nginx-deployment
app: nginx
replicas: 1
app: nginx
- name: nginx
image: nginx:1.17.6
- containerPort: 80

Save this as nginx-deployment.yaml and then run the following command to deploy it:

kubectl apply -f nginx-deployment.yaml

This will create a deployment and start a container running the nginx web server.

Step 6: Access the Application

To access the nginx web server that you just deployed, you need to expose it as a service. You can do this by running the following command:

kubectl expose deployment nginx-deployment --type=NodePort --port=80

This will create a service that maps the container port 80 to a random port on the host machine. You can now access the nginx web server by opening a web browser and navigating to http://<minikube ip>:<nodeport> where <minikube ip> is the IP address of the Minikube node (which you can get by running minikube ip) and <nodeport> is the random port that was assigned to the nginx service.
