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 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 Minikube==
−
 
 
−
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.
