Day 3(15th October): Journey To Devops Pro — Vagrant Installation and Setup

What is Vagrant?

Vagrant is a tool for building and managing virtual machine environments in a single workflow. It makes life easier by lowering development environment setup time and increasing productivity.

Now let us understand this using a diagram

Managing various VM and configuring it is quite tedious. So using vagrant we can able to manage, configure and run multiple VM using a file known as “Vagrant File”.

A Vagrant file can keep the configuration of the VM such as OS, RAM, storage, and so on. when we run vagrant up command in a terminal, vagrant reads through the vagrant file and starts executing and creating VM according to the configuration.

How to Install and Setup CentOS using Vagrant?

Pre-requisite: Download Virtual Box
