9. “Keep development, staging, and production as similar as possible” - http://12factor.net/ Text Dev/Prod Parity Concept Friday, 4 October 13
10. Snowflake Servers http://martinfowler.com/bliki/SnowflakeServer.html Friday, 4 October 13
11. Past and Present problems •Not straightforward. • Uniqueness. • Switching between projects is difficult. • Local dev environments differ from production. Friday, 4 October 13
12. How do we solve these problems ? http://www.flickr.com/photos/83633410@N07/7658225516/ Friday, 4 October 13

14. “Every so often, you encounter software that immediately strikes you with its combination of clarity, simplicity, power, and usefulness.” - Jeff Sussna Ingineering.IT in the foreward of Vagrant up and running by Mitchell Hashimoto Friday, 4 October 13
15. What is the Vagrant Concept? “A tool to transparently manage all the complex parts of modern development within a virtual environment without affecting the everyday workflow of the developer too much.” - http://www.vagrantup.com Friday, 4 October 13
16. $ vagrant Usage: vagrant [-v] [-h] command [<args>] -v, --version Print the version and exit. -h, --help Print this help. Available subcommands: box destroy halt help init package plugin provision reload resume ssh ssh-config status suspend up For help on any individual command run `vagrant COMMAND -h` Vagrant is a command line tool Friday, 4 October 13
17. Provider - virtualisation Building Blocks of Vagrant Vagrant Provisioner Friday, 4 October 13
18. Vagrant Workflow • When you done with the dev environment vagrant destroy [vn-name] • To access the virtual machine via ssh vagrant ssh • When you finished work for the day vagrant halt vagrant up • Once Configured one command to bring up you vagrant dev environment Friday, 4 October 13
19. Lets build a vagrant environment •Download Virtual Box http://download.virtualbox.org/virtualbox •Download Vagrant Installer http://downloads.vagrantup.com Friday, 4 October 13
20. Generate a VagrantFile $ vagrant init precise64 Box name http://files.vagrantup.com/precise64.box Box Friday, 4 October 13
21. Generated VagrantFile Vagrant.configure("2") do |config| config.vm.box = "precise64" config.vm.box_url = "http://files.vagrantup.com/precise64.box" end Box name Box location $ vagrant up Friday, 4 October 13
22. Box Files •Every Vagrant development environment needs a box file to build off. •Box files are specific to the type of provider. http://docs.vagrantup.com/v2/boxes.html $ vagrant box add name url Friday, 4 October 13
23. Four methods to create a box file •Download a box file from http://www.vagrantbox.es •Using the instructions off - (not recommended) http://docs-v1.vagrantup.com/v1/docs/base_boxes.html •VeeWee https://github.com/jedi4ever/veewee •Packer http://www.packer.io/docs/builders/virtualbox.html In a future version of vagrant packer will be integrated. Friday, 4 October 13
24. Generated VagrantFile Vagrant.configure("2") do |config| config.vm.box = "precise64" config.vm.box_url = "http://files.vagrantup.com/precise64.box" end $ vagrant init precise64 http://files.vagrantup.com/precise64.box $ vagrant up Friday, 4 October 13
25. Provisioning your vagrant machine •Need a configuration management tool. •Main benefits are ease of use, repeatability, automation and improving parity between development and production. Friday, 4 October 13
26. Puppet Chef Ansible Shell Vagrant out the box supports Friday, 4 October 13
27. Chef Puppet Puppet and Chef Puppet Apply Stand Alone Chef Client Client Server model Chef Solo Stand Alone Puppet Agent Client Server model Friday, 4 October 13
28. Puppet and Chef Stand Alone Stand Alone •Built by Puppetlabs. •Written in ruby you describe the system as a set of resources using a resource abstraction language. Puppet Puppet Apply •Built by Opscode. •Written in ruby uses a domain specific language (DSL). Chef Chef Solo Friday, 4 October 13
29. •In your Chef(cookbooks and recipes) or Puppet (modules and manifests) •What software is installed. •How the software is configured. •What services are running. Chef Solo Puppet Apply Friday, 4 October 13
