Vagrant is an open source tool that allows users to create and manage virtual machine environments. It provides a command line interface to define VMs using a Vagrantfile configuration file and control their lifecycle. Vagrant aims to simplify setting up reproducible development environments by automating the configuration of VMs and removing the need to install software locally. It supports provisioning VMs automatically through scripts and managing multiple coordinated VMs through a single configuration.

● Synced Folder - Allows vagrant to share files
between Host computer and the vagrant box
● Provisioning – Allows to automatically run
some script after virtual machine is installed
● Multi machine – Allows to create multiple VM
with same Vagrantfile

13. Demo 2

Multiple machines are defined within
the same project Vagrantfile
Via config.vm.define

17. Deployed 4 vagrant boxes in less

18. Creating your own boxes
● vewee - Automated way of creating virtualboxes
● It also supports Virtualbox,VMWare fusion

19. Whats next?

20. ● Currently I am working on combining Vagrant
with Virtual LTSP server
● Vagrant advantage is easy and quick to deploy
● LTSP allows computers of a LAN to boot
through network from a single server
● Combining these 2 would definitely be a cool
project
