Introduction

Minikube is a lightweight Kubernetes implementation that creates a VM on your local machine and deploys a simple cluster containing only one node. This is ideal for developers who want to try out Kubernetes or develop with it daily. Installing Minikube on Ubuntu 22.04 and 20.04 is straightforward, and this guide will show you how.

Prerequisites

Before we begin, ensure you have the following:

  • A machine running Ubuntu 22.04 or 20.04
  • At least 2GB of RAM and 20GB of disk space available
  • A user account with sudo privileges
  • Internet access

Step 1: Update Your System

First, it's always a good idea to update your system to ensure all existing packages are up-to-date. Open your terminal and run the following commands:

sudo apt update sudo apt upgrade -y

Step 2: Install Required Packages

Minikube requires a few packages to be installed on your system. These include curl, conntrack, and apt-transport-https. Install them with the following command:

sudo apt install -y curl apt-transport-https ca-certificates software-properties-common

Step 3: Install Docker

Minikube supports multiple container runtimes, but Docker is the most commonly used. To install Docker, follow these steps:

  1. Add Docker’s official GPG key:

    curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo gpg --dearmor -o /usr/share/keyrings/docker-archive-keyring.gpg

  2. Set up the stable repository:

    echo "deb [arch=$(dpkg --print-architecture) signed-by=/usr/share/keyrings/docker-archive-keyring.gpg] https://download.docker.com/linux/ubuntu $(lsb_release -cs) stable" | sudo tee /etc/apt/sources.list.d/docker.list > /dev/null

  3. Install Docker Engine:

    sudo apt update sudo apt install -y docker-ce docker-ce-cli containerd.io

  4. Verify Docker Installation:

    sudo systemctl status docker

Step 4: Install kubectl

kubectl is the command-line tool for interacting with Kubernetes clusters. Install kubectl by following these steps:

  1. Download the latest release:

    curl -LO "https://dl.k8s.io/release/$(curl -L -s https://dl.k8s.io/release/stable.txt)/bin/linux/amd64/kubectl"

  2. Install kubectl:

    sudo install -o root -g root -m 0755 kubectl /usr/local/bin/kubectl

  3. Verify kubectl installation:

    kubectl version --client

Step 5: Install Minikube

Now it's time to install Minikube. Follow these steps:

  1. Download the latest Minikube release:

    curl -LO https://storage.googleapis.com/minikube/releases/latest/minikube-linux-amd64

  2. Install Minikube:

    sudo install minikube-linux-amd64 /usr/local/bin/minikube

  3. Verify Minikube installation:

    minikube version

Step 6: Start Minikube

With Minikube installed, you can now start your Kubernetes cluster. Use the following command to start Minikube with Docker as the driver:

minikube start --driver=docker

Minikube will download the necessary images and set up the cluster. This might take a few minutes.

Step 7: Verify Minikube Installation

To ensure Minikube is running correctly, check the status of the cluster:

minikube status

You should see output indicating that the cluster is running. Additionally, you can run a test deployment to confirm everything is working:

  1. Create a deployment:

    kubectl create deployment hello-minikube --image=k8s.gcr.io/echoserver:1.4

  2. Expose the deployment:

    kubectl expose deployment hello-minikube --type=NodePort --port=8080

  3. Get the URL to access the service:

    minikube service hello-minikube --url

  4. Open the URL in your browser:

    curl $(minikube service hello-minikube --url)

You should see a response from the echo server, indicating that your Minikube cluster is functioning correctly.

Conclusion

Installing Minikube on Ubuntu 22.04 and 20.04 is a straightforward process if you follow these steps. By setting up Minikube, you now have a powerful tool to develop, test, and experiment with Kubernetes locally. Enjoy exploring Kubernetes and building your containerized applications!

Compelling Summary: Minikube installation on Ubuntu 22.04 | 20.04 enables a local Kubernetes cluster setup, perfect for development and testing. Follow these steps to get started efficiently.
