How To Install Minikube on Manjaro

Kubernetes has become a cornerstone in modern software development, enabling developers to manage containerized applications efficiently. For those looking to experiment with Kubernetes locally, Minikube serves as an invaluable tool. This article will guide you through the process of installing Minikube on Manjaro, a popular Arch-based Linux distribution. By the end of this guide, you’ll have a fully functional local Kubernetes cluster ready for development and testing.

Understanding Minikube

Minikube is a lightweight Kubernetes implementation that creates a virtual machine on your local machine, allowing you to run Kubernetes clusters for testing and development purposes. It simplifies the process of setting up a Kubernetes environment, making it accessible even to those who are new to container orchestration.

Some of the benefits of using Minikube include:

• Easy setup and configuration for local development.
• Support for multiple drivers, including Docker and KVM.
• The ability to test applications in a Kubernetes environment without needing a cloud provider.

Before proceeding with the installation, ensure your system meets the following requirements:

• A minimum of 2 GB RAM (4 GB recommended).
• At least 20 GB of free disk space.
• A compatible CPU with virtualization support (Intel VT-x or AMD-V).

Prerequisites for Installation

Hardware Requirements

To run Minikube effectively on Manjaro, your hardware should meet the following specifications:

• CPU: A dual-core processor is recommended.
• RAM: At least 2 GB of RAM is necessary; however, 4 GB or more will provide better performance.
• Disk Space: Ensure you have at least 20 GB of free disk space for the Minikube installation and its components.

Software Requirements

You will need to install several software packages before setting up Minikube. These include:

• Docker: A platform for developing, shipping, and running applications in containers.
• Kubectl: The command-line tool for interacting with Kubernetes clusters.
• KVM (Kernel-based Virtual Machine): A virtualization solution for running virtual machines on Linux.

You can check whether these packages are already installed by running the following commands in your terminal:

docker --version
kubectl version --client
virsh --version

Step 1: Update Your System

The first step in preparing your Manjaro system for Minikube is to ensure that all packages are up-to-date. Keeping your system updated helps avoid compatibility issues during installation. Open your terminal and execute the following command:

sudo pacman -Syu

This command will synchronize your package database and update all installed packages to their latest versions. After completing this step, reboot your system if prompted.

Step 2: Install Required Dependencies

Installing Docker

Docker is essential for running containers in Minikube. To install Docker on Manjaro, use the following command:

sudo pacman -Sy docker

Once installed, start and enable the Docker service so that it runs automatically on boot:

sudo systemctl start docker
sudo systemctl enable docker

You can verify that Docker is running by executing:

sudo systemctl status docker

Installing KVM and Other Dependencies

KVM is required for virtualization when using Minikube. Install KVM and other necessary packages with the following command:

sudo pacman -Sy qemu libvirt dnsmasq

Add your user to the `libvirt` group to manage virtual machines without root privileges:

sudo usermod -aG libvirt $(whoami)

You will need to log out and log back in for this change to take effect. After logging back in, start the necessary services with these commands:

sudo systemctl start libvirtd
sudo systemctl enable libvirtd
sudo systemctl start dnsmasq
sudo systemctl enable dnsmasq

Step 3: Install Minikube

Using AUR (Arch User Repository)

The easiest way to install Minikube on Manjaro is through the Arch User Repository (AUR). If you don’t have an AUR helper like `yay`, install it first by following these steps:

sudo pacman -S yay

Now you can install Minikube using `yay`:

yay -Sy minikube-bin

This command will download and install the latest version of Minikube from AUR. Once installed, verify that Minikube is set up correctly by checking its version:

minikube version

Step 4: Configure Minikube

The next step involves configuring Minikube to use KVM as its driver. This configuration allows Minikube to create virtual machines efficiently. Execute the following command in your terminal:

minikube config set driver kvm2

This command sets KVM as the default driver for running Minikube instances. You can also check your current configuration at any time using:

minikube config view

Step 5: Start Your Minikube Cluster

You are now ready to start your Minikube cluster. Run the following command in your terminal:

minikube start --driver=kvm2

This command initiates the process of downloading the necessary ISO images and creating a virtual machine. The startup process may take several minutes depending on your internet speed and system performance.

Step 6: Verify the Cluster Status

A successful startup will display several messages indicating that components are being created. To verify that your cluster is running correctly, use these commands:

minikube status
kubectl cluster-info

The output should confirm that both the control plane and other components are up and running. If you encounter any issues, common troubleshooting steps include checking Docker service status or ensuring KVM is properly configured.

Step 7: Accessing the Kubernetes Dashboard

The Kubernetes dashboard provides a web-based interface for managing your cluster. To enable and access it, run this command:

minikube dashboard

This command will automatically open a new browser window displaying the dashboard interface, where you can view cluster resources, manage deployments, and monitor application performance.

Troubleshooting Common Issues

If you encounter problems during installation or while starting your cluster, consider these troubleshooting tips:

• Error: “KVM not found”: Ensure that virtualization is enabled in your BIOS settings and that KVM modules are loaded correctly.
• Error: “Minikube start failed”: Check if Docker is running properly by executing `sudo systemctl status docker`.
• Error: “Unable to connect to the server”: Verify that kubectl is configured correctly by running `kubectl config view`.
• Error: “Permission denied”: Make sure your user is part of the `libvirt` group as mentioned earlier.
