Vagrant is a command-line  tool for building and managing virtual machine environments. By default,  Vagrant can provision machines on top of VirtualBox, Hyper-V, and  Docker. Other providers such as Libvirt (KVM), VMware and AWS can be  installed via the Vagrant plugin system.

Vagrant is typically used by developers to set up a development environment that matches the production environment.

In  this tutorial, we’ll show you how to install Vagrant on an Ubuntu 18.04  machine. We’ll be using the VirtualBox provider, which is the default  provider for Vagrant. The same steps can be used for Ubuntu 16.04 Xenial  Xerus.

Prerequisites

Before continuing with this tutorial, make sure you are logged in as a user with sudo privileges.

Install Vagrant on Ubuntu

To install Vagrant on your Ubuntu system, follow these steps:

1. Installing VirtualBox

As  mentioned in the introduction, we will provision the machines on top of  VirtualBox, so the first step is to [install the VirtualBox package]  which is available in the Ubuntu’s repositories:

sudo apt install virtualbox

If you want to install the latest VirtualBox version from the Oracle repositories, check this tutorial.

2. Installing Vagrant

The  Vagrant package, which is available in Ubuntu’s repositories, is pretty  outdated. We’ll download and install the latest version of Vagrant from  the official Vagrant site.

At the time of writing this article,  the latest stable version of Vagrant is version 2.2.6. Before continuing  with the next steps, check the Vagrant Download page to see if a newer version is available.

Start by updating the package list with:

sudo apt update

Download the Vagrant package using the following curl command:

curl -O https://releases.hashicorp.com/vagrant/2.2.6/vagrant_2.2.6_x86_64.deb

Once the .deb file is downloaded, install it by typing:

sudo apt install ./vagrant_2.2.6_x86_64.deb

3. Verify Vagrant installation

To verify that the installation was successful, run the following command which prints the Vagrant version:

vagrant --version

The output should look something like this:

Vagrant 2.2.6

Getting Started with Vagrant

Now that Vagrant is installed on your Ubuntu system let’s create a development environment.

The  first step is to create a directory which will be the project root  directory and hold the Vagrantfile file. Vagrantfile is a Ruby file that  describes how to configure and provision the virtual machine.

Create the project directory and switch to it with:

mkdir ~/my-first-vagrant-project

Next, initialize a new Vagrantfile using the vagrant init command and specify the box you want to use.

Boxes  are the package format for the Vagrant environments and are  provider-specific. You can find a list of publicly available Vagrant  Boxes on the Vagrant box catalog page.

In this example, we will use the centos/7 box. Run the following command to initialize a new Vagrantfile:

vagrant init centos/7
A `Vagrantfile` has been placed in this directory. You are now
ready to `vagrant up` your first virtual environment! Please read
the comments in the Vagrantfile as well as documentation on
`vagrantup.com` for more information on using Vagrant.

You can open the Vagrantfile, read the comments and make adjustment according to your needs.

Run the vagrant up command to create and configure the virtual machine as specified in the Vagrantfile:

vagrant up
==> default: Configuring and enabling network interfaces...
    default: SSH address: 192.168.121.74:22
    default: SSH username: vagrant
    default: SSH auth method: private key
==> default: Rsyncing folder: /home/black/Vagrant/my-first-vagrant-project/ => /vagrant

Vagrant also mounts the project directory at /vagrant in the virtual machine which allows you to work on your project’s files on your host machine.

To ssh into the virtual machine, run:

vagrant ssh

You can stop the virtual machine with the following command:

vagrant halt

The following command stops the machine if it is running, and destroys all resources created during the creation of the machine:

vagrant destroy

Conclusion

You  have learned how to install and use Vagrant on your Ubuntu 18.04  machine. We have also shown you how to create a basic development  environment.
