Vagrant - Getting Started

15 Jan 2016

Vagrant Logo

Vagrant is a tool for managing virtual machines. It provides easy to configure, reproducible and portable work environments.

Machines are provisioned on top of :

  • VirtualBox
  • VMWare
  • AWS etc.

Vagrant helps to isolate dependencies and their configuration within a single disposable, consistent environment.

Up and Running

mkdir vagrant_getting_started
cd vagrant_getting_started

#Create Vagrant File
vagrant init <boxname>

#Start Vagrant Box
vagrant up

#Connecting to Vagrant Box
vagrant ssh

Using Boxes

Vagrant.configure("2") do |config|
  config.vm.box = "hashicorp/precise32"
end

Vagrant.configure("2") do |config|
  config.vm.box = "hashicorp/precise32"
  config.vm.provision :shell, path: "bootstrap.sh"
end

#!/bin/bash

sudo apt-get upgrade
sudo apt-get -y install build-essential
sudo apt-get -y install nodejs npm node-semver
sudo apt-get -y install git
sudo apt-get -y install openjdk-7-jdk

Vagrant.configure("2") do |config|
  config.vm.box = "hashicorp/precise32"
  config.vm.provision :shell, path: "bootstrap.sh"
  config.vm.network :forwarded_port, guest: 80, host: 4567
  config.vm.network :forwarded_port, guest: 5000, host: 5000
end
