❏Lowers development environment setup time

❏Development - Production parity

❏No more “Works on my machine” excuses

Why Vagrant❏Easy to configure

❏Reproducible and portable

❏Single consistent workflow

❏Industry-standard tools integration

Benefits of Vagrant❏Isolate dependencies and their configuration❏A single disposable, consistent environment❏Creates a single Vagrantfile for a project and share with other

configured for work.

Let us create a VM❏ Ubuntu Server 14.04 (trusty64)

❏ Git

❏ LAMP Stack

❏ Composer

❏ Node

❏ Redis

❏ Memcached

❏ Beanstalkd

❏ Supervisor

❏ PHPMyAdmin

❏ The Web Application:

➭ A laravel installation

➭ A mysql database for the application

Initializing Vagrant

9

❏ mkdir vagrant-test

❏ cd vagrant-test

❏ laravel new testvagrant

A fresh laravel will be installed in testvagrant directory.

❏ vagrant init

A new Vagrantfile will be placed in the vagrant-test directory.

❏ vagrant up

❏ Ansible

❏ Salt

❏ Docker

An open platform for distributed applications for developers and sysadminsBuild, Ship, Run

13

What Docker is❏High level

❏ A lightweight VM

❏ Own process space

❏ Own network interface

❏ Can run stuff as root

14

❏ Low level❏ Container = isolated

processes

❏ Share kernel with host

❏ <<application container>>

Why Docker❏Run everywhere

❏ Regardless of kernel version

❏ Regardless of host distro

❏ Physical or virtual, cloud or not

❏ Container and host architecture must match...

15

❏Run anything

❏ If it can run on the host, it can run in the container

❏ If it can run on a Linux kernel, it can run

VMs vs. Containers

16

Why Container are Lightweight

17

Install Docker❏Go to https://docs.docker.com/engine/installation/
