How to Install Minikube on Ubuntu

Minikube is a lightweight, portable, and easy-to-use way to run Kubernetes on your laptop. As a developer, you can use Minikube to test, develop, and deploy Kubernetes applications locally, without the need for a full-fledged Kubernetes cluster. This approach enables you to accelerate your development cycle, reduce costs, and increase productivity.

Minikube provides a rapid development cycle, enabling you to iterate quickly, experiment with new ideas, and validate your code. It supports various Kubernetes features, including Deployments, Services, and Persistent Volumes. With Minikube, you can create a Kubernetes cluster in minutes, deploy your application, and start testing it immediately. This streamlined approach ensures that you can focus on writing code rather than managing infrastructure.

To set up a local Kubernetes development environment, you need to install Minikube on your Ubuntu machine. This guide will walk you through the installation process, covering the prerequisites, installation steps, and troubleshooting tips. By the end of this guide, you will have a fully functional Minikube installation on your Ubuntu machine, ready to power your Kubernetes development.

Method 1: Installing Minikube using dpkg on Ubuntu

To Minikube install Ubuntu, you’ll need to download the Minikube package and then install it using the dpkg package manager.

Step 1: Downloading the Minikube Package

First, you need to download the Minikube package from the official Minikube repository. You can do this using the following command:

curl -LO https://storage.googleapis.com/minikube/releases/latest/minikube_latest_amd64.deb
desktop-curl

Here’s what this command does:

  • curl is a command-line tool for transferring data to and from a web server using HTTP, HTTPS, SCP, SFTP, TFTP, and more.
  • -LO are options used with curl. -L stands for –location, which tells curl to follow redirects. -O stands for –output, which specifies the output file name. In this case, the output file name is not specified, so curl will use the last part of the URL as the file name, which is minikube_latest_amd64.deb.
  • The URL points to the latest version of Minikube for 64-bit AMD architectures (which includes most modern computers).

When you run this command, curl will download the Minikube installation package to your current working directory.

Step 2: Installing the Minikube Package

Once the package is downloaded, you can install it using the following command:

sudo dpkg -i minikube_latest_amd64.deb
desktop-sudo

Here’s what this command does:

  • sudo is a command to run the subsequent command with superuser privileges. This is necessary because installing packages requires administrative access.
  • dpkg is the package manager for Debian-based systems (such as Ubuntu). dpkg is used to install, remove, and manage packages.
  • -i is the option to install a package.
  • minikube_latest_amd64.deb is the package file that was downloaded in the previous step.

When you run this command, dpkg will install the Minikube package, which will make Minikube available on your system.

Step 3: Verifying Minikube Installation

After installing Minikube, you can verify that it’s working correctly by running the following command:

minikube version
minikube-version

When you run the command, it displays the version of Minikube installed on your system, along with the commit information. 

The commit hash is a unique identifier that corresponds to a specific commit in the Minikube Git repository. It’s a way to identify the exact code changes that are included in the Minikube version.

Here’s why the commit hash is important:

  • Reproducibility: By including the commit hash, you can reproduce the same version of Minikube, even if you’re working on a different machine or environment.
  • Debugging: If you encounter issues with Minikube, the commit hash can help the Minikube team or other developers identify the specific code changes that might be causing the problem.
  • Tracking changes: The commit hash allows you to track changes in the Minikube codebase and to see what’s new in each version.

Method 2: Installing Minkube using Snap on Ubuntu

This guide walks you through installing Minikube using the Snap package manager, a popular way to distribute software on Linux systems.

Step 1: Installing Snap

First, you need to make sure that snap is already installed which you can do by executing the below command:

sudo apt update && sudo apt install snapd
apt-install

This command updates system packages and installs the snap package manager if it isn’t already installed.  

Step 2: Installing Minikube 

Next, execute the below command to download and install Minikube Ubuntu:

sudo snap install minikube
snap-install

Step 3: Verifying Minikube Installation

Lastly, you can verify if Minikube has been installed correctly by displaying its version using the below command:

snap run minikube version
snap-run

The first method is more reliable as its installing the latest version compared to the second method.

What is Minikube?

Minikube is a single-node Kubernetes cluster that runs on your laptop or workstation. It provides a self-contained environment for developing, testing, and deploying Kubernetes applications. Minikube supports various Kubernetes features, including:

  • Multi-container pods: Run multiple containers within a pod to create complex applications.
  • Persistent Volumes: Store data persistently across pod restarts and deployments.
  • Services: Expose applications to the outside world using services.
  • Ingress: Route traffic to multiple services using ingress resources.

Benefits of Using Minikube

Minikube offers several benefits for local Kubernetes development:

  • Faster Development: Iterate quickly on your application code without waiting for a remote cluster to spin up.
  • Easy Testing: Test your application locally before deploying it to a production cluster.
  • Cost-Effective: Reduce costs by using local resources instead of a cloud-based cluster.

Use Cases for Minikube

Minikube is useful in various scenarios:

Development: Use Minikube to develop and test Kubernetes applications locally before deploying them to a production cluster.

  • Testing: Leverage Minikube to create a local test environment for your Kubernetes applications.
  • CI/CD Pipelines: Integrate Minikube into your CI/CD pipelines to automate the testing and deployment of Kubernetes applications.
  • Training and Education: Use Minikube to learn Kubernetes concepts and practices without setting up a full-fledged cluster.
