Documentation of how you can install and use Vagrant right away

Here,
I'll document my a simple process of spinning up three Ubuntu vm in your machine using Vagrant.

Vagrant is quite popular tool developed by Hashicorp. It's quite useful of quickly creating virtual machine and test them. You can easily delete them with vagrant destroy

Step 1: Install Vagrant (https://developer.hashicorp.com/vagrant/install) (use official documentation, chatgpt/gemini if you have no idea)

step 2: Install Oracle VM virtualbox (https://www.virtualbox.org/wiki/Downloads)

step 3: Install git bash (I prefer it for some reason. You can use powershell/terminal as well), run mkdir ubuntu, cd ubuntu and type vagrant init and enter

step 4: I'm goint to spin up three vm named first, second and third

vagrant uses boxes (think of them as pre-packaged virtual machine) to spin up your VM. you can find your favourite boxes at (https://app.vagrantup.com/)

Being a Gen-z engineer, I generated a vagrantfile with above description using Google Gemini and edited it to Vagrantfile ( yes it don't have any extension).

Step 4: Now run vagrant up

Now it should start creating your three ubuntu vm machines like:

Now you can ssh to your vm using vagrant ssh {name of your vm}) like below. I'll use vagrant ssh first for now.

Done. Now you've successfully ssh'ed to your newly created Ubuntu virtual machine.

PS : learn to configure further changes as per your requirement by editing Vagrantfile. You can pre-install packages, open ports, create users/group and many more. Start learning them, you'll be Vagrant pro in no time.
