Introduction
 
Minikube is an open source tool that allows you to set up a single-node Kubernetes cluster on your local machine. The cluster is run inside a virtual machine and includes Docker, allowing you to run containers inside the node.
 
  
This is an excellent way to test in a Kubernetes environment locally, without using up too much resources.

How to install Miikube on Ubuntu.
 
Prerequisites
 
A system running Ubuntu 18.04 Bionic Beaver or Ubuntu 20.04
 
A user account with sudo privileges
 
 
 
Access to a terminal window / command line (Ctrl+Alt+T, search > terminal)
 
 
 
How to Install Minikube on Ubuntu
 
To install Minikube on Ubuntu, follow the steps outlined below. Besides installation instructions, you can also find some basic commands for working inside your local single-node cluster.
 
 
 
Step 1: Update System and Install Required Packages
 
Before installing any software, you need to update and upgrade the system you are working on. To do so, run the commands:
 
  
 
  sudo apt-get update -y
 
  sudo apt-get update -y
 
  sudo apt-get upgrade -y
 
  sudo apt-get upgrade -y
 
Updating the software package list on Ubuntu.
 
Also, make sure to install (or check whether you already have) the following required packages:
 
 
 
  sudo apt -y install curl apt-transport-https
 
  sudo apt -y install curl apt-transport-https
 +
sudo apt -y install virtualbox virtualbox-ext-pack
  
In the image below, the output informs that the packages are already installed.

Install dependencies for installing Minikube.
 
Step 2: Install VirtualBox Hypervisor
 
As mentioned above, you need a virtual machine in which you can set up your single node cluster with Minikube. Depending on your preference, you can use VirtualBox or KVM.
 
 
 
This guide will show you how to install Minikube with VirtualBox.
 
 
 
1. To install VirtualBox on Ubuntu, run the command:
 
 
 
sudo apt install virtualbox virtualbox-ext-pack
 
Terminal VirtualBox installation process in the Linux terminal.
 
 
 
2. Confirm the installation with y and hit Enter.
 
 
 
3. Next, the licence agreement appears on the screen. Press Tab and then Enter to continue.
 
 
 
VirtualBox licence agreement.
 
 
 
4. The installer asks you to agree with the terms of the VirtualBox PUEL license by selecting Yes.
 
 
 
Setting up virtualbox-ext-pack.
 
 
 
5. Wait for the installation to complete and then move on to the next step.
 
 
 
Note: For the VirtualBox hypervisor to work, hardware virtualization must be enabled in your system BIOS.
 
 
 
Step 3: Install Minikube
 
With VirtualBox set up, move on to installing Minikube on your Ubuntu system.
 
 
 
1. First, download the latest Minikube binary using the wget command:
 
  
 
  sudo su
 
  sudo su
 
  cd /usr/local/src/
 
  cd /usr/local/src/
 
  wget https://storage.googleapis.com/minikube/releases/latest/minikube-linux-amd64
 
  wget https://storage.googleapis.com/minikube/releases/latest/minikube-linux-amd64
 
Downloading the Minikube binary to install Minikube on Ubuntu 18.04.
 
2. Copy the downloaded file and store it into the /usr/local/bin/minikube directory with:
 
  
 
  sudo cp minikube-linux-amd64 /usr/local/bin/minikube
 
  sudo cp minikube-linux-amd64 /usr/local/bin/minikube
 
 
3. Next, give the file executive permission using the chmod command:
 
 
 
  sudo chmod 755 /usr/local/bin/minikube
 
  sudo chmod 755 /usr/local/bin/minikube
 
 
4. Finally, verify you have successfully installed Minikube by checking the version of the software:
 
 
 
  minikube version
 
  minikube version
  
The output should display the version number of the software, as in the image below.
+
==Install Kubectl==
 
 
Check Minikube version.
 
Step 4: Install Kubectl
 
To deploy and manage clusters, you need to install kubectl, the official command line tool for Kubernetes.
 
 
 
1. Download kubectl
 
  
 
  sudo su
 
  sudo su
Line 92: Line 27:
 
  cd /usr/local/src
 
  cd /usr/local/src
 
  curl -LO https://storage.googleapis.com/kubernetes-release/release/`curl -s https://storage.googleapis.com/kubernetes-release/release/stable.txt`/bin/linux/amd64/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
 
2. Make the binary executable by typing:
 
  
 
  chmod +x ./kubectl
 
  chmod +x ./kubectl
 
3. Then, move the binary into your path with the command:
 
 
 
  sudo mv ./kubectl /usr/local/bin/kubectl
 
  sudo mv ./kubectl /usr/local/bin/kubectl
 
4. Verify the installation by checking the version of your kubectl instance:
 
 
 
  kubectl version -o json
 
  kubectl version -o json
  
Step 5: Start Minikube
+
==Operasikan Minikube==
Once you have set up all the required software, you are ready to start Minikube.

Access Minikube Dashboard
 
Minikube comes with a dashboard add-on by default. The web dashboard provides a way to manage your Kubernetes cluster without actually running commands in the terminal.
 
 
 
To enable and access the Minikube dashboard via terminal, run the following command:
 
  
 
  minikube dashboard
 
  minikube dashboard
 
Enabling and accessing the Minikube dashboard.
 
Once you exit the terminal, the process will end and the Minikube dashboard will shut down.
 
 
Alternatively, you can access the dashboard directly via browser.
 
 
To do so, acquire the dashboard’s IP address:
 
 
 
  minikube dashboard --url
 
  minikube dashboard --url
 
Terminal command to get the Minikube dashboard URL for accessing it via browser.
 
Access your Minikube dashboard by browsing to your dashboard’s IP address.
 
 
Conclusion
 
By following this article, you should have successfully installed and configured Minikube on Ubuntu 18.04 or 20.04. You can now test and master the art of Kubernetes on your local machine with the help of a single Minikube node.
