3. CHANGEOVERTIME
“How long does it take you
to set up a new XYZ project?”

4. COLLABORATION
How do you share projects with colleagues?

5. YOU BUILD IT –YOU RUN IT!
“But it worked on my machine!”

6. How canVagrant help you?
• Set up ANY projects in minutes
• Have it “to go”
• Share it with others
• Have a “copy” of your production server

7. Technology Stack
VirtualBox
Free Open SourceVirtualizationTool
Chef
Configuration Management
Framework
Vagrant
“Remote Control” forVirtualBox

8. What isVagrant?
• Building tool for portable dev environments
• Tool for distributing work environments
• Written in Ruby
• Open Source
• Build upon well-established tools

9. Vagrant Components
• Vagrant Box
• Vagrantfile
• Provisioners
• Providers

10. Vagrant Boxes
• Basically a “tweaked” virtual machine Image
• Used as base layer for all further provisioning
• Many pre-installed boxes available online:

12. $ vagrant box add {title} {url}
$ vagrant init {title}
$ vagrant up

14. Provisioners
• „Where the magic happens“
– Installing packages and software
– Configuration and starting of services
– E.g. creating vhost, database, ...
• Run once the box is booted inVirtualBox

15. What is Chef?
• Configuration Management automation tool
• Written in Ruby
– Provides easy-to-learn (?) DSL
• „Infrastructure as code“
– Use versioning
– Use tests, Continuous Integration & Delivery

17. ChefTools
• Chef Client
• Chef Server
• Knife
• …too many

18. Chef Components
• Cookbooks, Recipes, Resources
• Attributes
• Templates
• Roles
• and many more…

19. └── cookbook_name
├── attributes
│ └── default.rb
├── recipes
│ └── default.rb
├── templates
│ └── default
│ └── template.erb
└── metadata.rb

22. Provisioning
Run Chef in yourVagrantBox
sudo chef-solo –c solo.rb -j config.json

23. chef run
vagrant up
import image
provision projects
mount cookbooks

24. Your ownVagrant Box
• The “Playbook-to-Cookbook-Algorithm”
– Write installation steps in a text document
– Follow steps yourself, refine document
– Give document to someone else, refine again
– No changes in document  start writing
cookbooks

25. GenericWebProject
Cookbook
1. Install Packages for Apache, MySQL, PHP
2. Provision Webspace(s) and vhost(s)
3. Provision MySQL Database(s)
4. DownloadTYPO3 sources (or use Composer)
5. Clone your Git project

26. Next Step
• Provisioning of hosting servers with Chef
• BuildingVagrant Boxes on CI Server
• Vagrant Boxes for customers
• Codecoon

27. Summary
• Vagrant is a great tool for portable boxes
• Chef can help you manage your configuration
• „Infrastructure as Code“
• Same environment on dev and production
• DevOps brings devs and admins together
