Vagrant - Getting Started | Install ＞ Setup ＞ Use

Step 1 - Install Vagrant

https://www.vagrantup.com/downloads

Check Vagrant is installed using

vagrant --version

Step 2 - Select a VM Provider. Vagrant has direct support for VirtualBox, Hyper-V, Docker Install VirtualBox

https://www.virtualbox.org/wiki/Downl...

Step 3 - Create a new folder for Vagrant project

Step 4 - On terminal or command line navigate to the folder and initiate the vagrant project using

vagrant init

This will create a new Vagrantfile in the folder.

Vagrantfile is a configuration file that defines the settings for your virtual machine

Step 5 - Choose a box to use

https://app.vagrantup.com/boxes/search

A box is a pre-configured virtual machine image that you can use as a starting point for your virtual machine

Step 6 - Add the configuration of the box in the vagrant file.

For example, you could use the "ubuntu/bionic64" box by adding the following line to your

Vagrantfile : config.vm.box = "ubuntu/bionic64"

We can also directly add configuration for the virtual machine using the following commands

vagrant init centos/7 - (if vagrant file does not already exists)

vagrant box add centos/7 - will add box to vagrant, but will not create a Vagrant file)

Step 7 - Start the virtual machine using the command

vagrant up

This will create a new virtual machine using the box you selected and start it. The first time, Vagrant will download the box from the internet

Step 8 - SSH into the virtual machine

vagrant ssh

Vagrant Box - 7 Commands

1. vagrant box add - Adds a box to your local box repository

Example : vagrant box add ubuntu/focal64

2. vagrant box list - Lists all boxes in your local box repository

3. vagrant box outdated - Checks if any boxes in your local box repository are outdated

4. vagrant box update - Updates a box to a new version

Example : vagrant box update ubuntu/focal64

5. vagrant box repackage - Repackages a box with a new name and metadata

Example : vagrant box repackage ubuntu/focal64 --name my-new-box

6. vagrant box prune -Removes outdated boxes from your local box repository

7. vagrant box remove - Removes a box from your local box repository

vagrant box remove ubuntu/focal64

Location of VM boxes

Mac OS X and Linux: ~/.vagrant.d/boxes

Windows: C:/Users/USERNAME/.vagrant.d/boxes
