2. Introduction
• What is Vagrant?
• Created by Mitchell Hasimoto
• Provisioning Tools for Dev, Production & Test Environments
• Syntactic sugar around VMs and Containers
• Syntactic sugar around provisioning
• Why use Vagrant?
• Quick
• Easily replicate production on a Dev box
• Easily go production from a Dev box
• Mature, stable, proven

3. Step 1: Install Vagrant
• http://www.vagrantup.com/downloads.html
• Mac OSX
• Windows
• Debian/Ubuntu
• CentosOS/Redhat/Fedora

4. Step 2: Project Setup
$ mkdir vagrant_getting_started
$ cd vagrant_getting_started
$ vagrant init

5. Step 3: Select a Box
• http://www.vagrantbox.es
• Ubuntu, OpenSuse, OpenBSD, CentOS, Debian..
• Select Provider (VM or Container)

6. Step 4: Show/Edit Vagrantfile
VAGRANTFILE_API_VERSION = "2"
Vagrant.configure(VAGRANTFILE_API_VERSION) do |config|
config.vm.box = "precise64"
config.vb.box_url = "http://bit.ly/1gLmNF0"
end

7. Step 5: Up!
$ vagrant up
Step 6: Connect!
$ vagrant ssh

8. More Commands
• status : status of the machine
• halt : stop machine
• suspend : suspend machine
• reload : restar machine (load new vagrantfile)
• resume : resume suspended machine
• provision : force provisionning machine
• destroy : stop and delete machine
• box : manages boxes
• …

9. More Providers
(native or plugin)
• VMs:
• VirtualBox, KVM, Hyper-V, VMware, libvirt
• Containers:
• lxc, docker
• Services:
• AWS, DigitalOcean, HP Cloud, Joyent,
Rackspace, OpenStack, CloudStack, vSphere…

10. Customize
• config.vm.box* : Box information
• config.vm.network* : Network
• config.ssh* : SSH connection
• config.vm.synced_folder : Share folder
• config.vm.provider* : Custom provider settings
• config.vm.provision* : Provisioning (Puppet, Chef, Docker,
Shell…)

11. Provisioning?
• Automatically install software, alter configuration and more
• Shell Scripts
• File
• Puppet (Standalone & Agent)
• Chef (Solo & Client)
• Ansible
• Salt
• Docker!!!

12. • Open-Source Container for Dummies
• Create lightweight, portable, self-sufficient container from any
app.
• Build once… run anywhere
• Configure once… run anything
• Ecosystems! OS, VM’s, PaaS, IaaS…
• Base: LXC, OpenVZ, systemd-nspawn, libvirt-lxc, libvirt-sandbox,
qemu/kvm, Jails, Solaris Zones, chroot (0.9*)

13. Vagrant and Docker
• BOX = Machine
• Docker = Container (App package inside the Box)
• Functions: Pull, Build, Run
• Allow others provisioning (Shell, Puppet, Chef)

14. Docker in Vagrantfile
Vagrant.configure("2") do |config|
v = config.vm
v.box = "precise64"
v.box_url = "http://bit.ly/1gLmNF0"
v.network "forwarded_port", guest: 8080, host: 9292
v.provision "docker", images: ["parana/web-xe-ubuntu"]
v.provision "docker" do |d|
d.run "parana/web-xe-ubuntu", args: "-p 9292:8080"
end
end

15. Up!
$ vagrant up
Connect!

16. YES !!
