How To Install Vagrant on Ubuntu 20.04

Introduction

In this tutorial, we learn how to install Vagrant on Ubuntu 20.04. Vagrant is a command line utility for managing the life cycle of virtual machine. We can use vagrant to provision virtual machine on our computer / laptop using virtualization like VirtualBox, VMWare, Hyper-V or Libvirt (KVM) and also on cloud providers like Amazon Web Services (AWS). For this tutorial we will use Vagrant with VirtualBox

Prerequisites

Install Vagrant on Ubuntu 20.04

First, let’s add Hashicorp GPG key. This key will be used by apt to verify that the package we’re downloading is the Vagrant package created and published by Hashicorp.

curl -fsSL http<span class="hljs-variable">s:</span>//apt.releases.hashicorp.<span class="hljs-keyword">com</span>/gpg | sudo apt-key <span class="hljs-built_in">add</span> -

It should provide output OK. If it provides any error message you have to fix the error first before continue to the next step.

Secondly, add the vagrant apt repository using the command below.

sudo apt-<span class="hljs-keyword">add</span><span class="bash">-repository <span class="hljs-string">"deb [arch=amd64] https://apt.releases.hashicorp.com <span class="hljs-variable">$(lsb_release -cs)</span> main"</span></span>

After adding repository configuration, we need to update apt database using the command below.

sudo apt-<span class="hljs-built_in">get</span> <span class="hljs-keyword">update</span>

Now we can install Vagrant using the command below.

sudo apt-<span class="hljs-keyword">get</span> install vagrant

The output will be similar to below.

Check Vagrant version

Now vagrant is installed we can check installed vagrant version using the command below.

$ vagrant <span class="hljs-built_in">version</span>
Installed Version: <span class="hljs-number">2.2</span><span class="hljs-number">.17</span>
Latest Version: <span class="hljs-number">2.2</span><span class="hljs-number">.17</span>

You're <span class="hljs-built_in">running</span> an up-<span class="hljs-keyword">to</span>-<span class="hljs-built_in">date</span> <span class="hljs-built_in">version</span> <span class="hljs-keyword">of</span> Vagrant!

Using Vagrant

In this section we will use the installed Vagrant to spawn Ubuntu 20.06 virtual machine.

<span class="hljs-built_in">mkdir</span> focal64
<span class="hljs-built_in">cd</span> focal

Creating Vagrantfile for Ubuntu 20.04

To create new Vagrantfile for Ubuntu 20.04 we use vagrant init command.

<span class="hljs-attribute">vagrant</span> init ubuntu/focal64

The output will be similar to below.

A `Vagrantfile` has been placed <span class="hljs-keyword">in</span> this <span class="hljs-built_in">directory</span>. You are now
ready <span class="hljs-built_in">to</span> `vagrant up` your <span class="hljs-keyword">first</span> virtual environment! Please <span class="hljs-built_in">read</span>

Starting VirtualBox virtual machine with Vagrant

To start the virtualmachine, we can use the command below

<span class="hljs-attribute">vagrant up</span>

Since this is the first time we start Ubuntu 20.04 virtual machine, we will get output similar to output below:

SSH to vagrant box

To access the vagrant box we can use the command below:

<span class="hljs-attribute">vagrant ssh</span>

We will be greeted as if we are accessing an Ubuntu machine via SSH

$ vagrant ssh

To exit from the virtual machine you can type exit or press CTRL+D.

Destroying Vagrant Virtual Machine

To destroy the Vagrant managed virtual machine, we can use the command below

<span class="hljs-attribute">vagrant destroy</span>

Vagrant will prompt to ensure we want to destroy the virtual machine.

   <span class="hljs-keyword">default</span>: Are you sure you want <span class="hljs-keyword">to</span> destroy the <span class="hljs-string">'default'</span> VM? [y/N]

Enter Y

Summary

In this tutorial we learn how to install Vagrant on Ubuntu 20.04. We also learn the basic usage of Vagrant, from creating a Vagrantfile, starting up the instane, accessing the instance through SSH and destroying the instance.
