Installing Minikube on Linux

Install Minikube on Linux , Ubuntu, and Server

Overview

Before learning about Minikube, we should at least know about Kubernetes, because Minikube is one kind of Kubernetes that is commonly used.

Kubernetes is a portable, extensible, open source platform for managing containerized workloads and services, that facilitates both declarative configuration and automation. In other words, Kubernetes is a container manager that manages several containers to serve at one end and prevents the service from being down or overloaded by weighing all loads and balancing them throughout all containers at the same time. Put simply, Kubernetes is a multi-service manager.

Minikube is a lightweight Kubernetes implementation that creates a VM on your local machine and deploys a simple cluster containing only one node (node = machine/server). Minikube is available for Linux, macOS, and Windows systems. Minikube is the simplest and easiest-to-use type of Kubernetes if you have only one single server to run.

Prerequisites

• A server running on one of the following operating systems: Ubuntu 22.04, 20.04, 18.04, 16.04 or any other Debian-based distribution like Linux
• It’s recommended that you use a freshly installed OS to prevent any unexpected issues
• Access to the root user

Installation Steps

1. Installing Docker

In this article, we will be using Docker container as a base for Minikube. In case Docker is not installed

sudo apt-get install docker.io -y 
sudo usermod -aG docker $USER && newgrp docker

2. Updating system packages and installing Minikube dependencies

sudo apt update & sudo apt upgrade 
 sudo apt install -y curl wget apt-transport-https

3. Installing Minikube

Use the following curl command to download the latest Minikube binary:

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

Once the binary is downloaded, copy it to the path /usr/local/bin and set the executable permissions on it

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

Verify the minikube version

minikube version
 #output
minikube version: v1.32.0
commit: 8220a6eb95f0a4d75f7f2d7b14cef975f050512d

Note: At the time of writing this tutorial, the latest version of minikube was v1.32.0

4. Installing kubectl utility

kubectl is a command line used to interact with Kubernetes cluster. It is used for managing deployments, replica sets, services, etc. Use the following command to download the latest version of kubectl.

curl -LO https://storage.googleapis.com/kubernetes-release/release/$(curl -s https://storage.googleapis.com/kubernetes-release/release/stable.txt)/bin/linux/amd64/kubectl

Once Kubectl is downloaded, set the executable permissions on the Kubectl binary and move it to the path /usr/local/bin.

chmod +x kubectl
sudo mv kubectl /usr/local/bin/

Now verify the kubectl version

kubectl version -o yaml

5.Start minikube

As we stated in the beginning, we would be using docker as base for minikue, so start Minikue with the docker driver and run

minikube start --driver=docker

Perfect! The above picture confirms that the Minikube cluster has been confluenced and started successfully.

6. Verifying Installation

Run the below minikube command to check the status.

minikube status
 #output
minikube
type: Control Plane
host: Running
kubelet: Running
apiserver: Running
kubeconfig: Configured 

Run the following kubectl command to verify the Kubernetes version, node status, and cluster info.

 kubectl cluster-info

Kubernetes control plane is running at https://192.168.49.2:8443
CoreDNS is running at https://192.168.49.2:8443/api/v1/namespaces/kube-system/services/kube-dns:dns/proxy

To further debug and diagnose cluster problems, use 'kubectl cluster-info dump'.

kubectl get nodes
NAME       STATUS   ROLES           AGE     VERSION
minikube   Ready    control-plane   3m27s   v1.30.0

7. Managing Addons on minikube

By default, only a couple of addons are enabled during minikube installation. To see the addons in Minikube, run the below command.

minikube addons list

If you wish to enable any addons, run the below minikube command.

minikube addons enable metrics-server

Let’s assume we want to enable and access the Kubernetes dashboard. Run

 minikube dashboard

Use localhost output

Server use this commands

minikube dashboard --url

Follow next order

Run the command in background

kubectl proxy --address='0.0.0.0' --disable-filter=true &
  #output 
W0423 04:59:24.539492   15291 proxy.go:177] Request filter disabled, your proxy is vulnerable to XSRF attacks, please be cautious
Starting to serve on [::]:8001

Follow next order

Use server IP and port [::]:8001 and use url /api/v1/namespaces/kubernetes-dashboard/services/http:kubernetes-dashboard:/proxy/

http://server_ip:8001/api/v1/namespaces/kubernetes-dashboard/services/http:kubernetes-dashboard:/proxy/#/workloads?namespace=default
