  • 1. Vagrant for Developers
  • 2. Presenter - Technology Architect at Accenture - 10+ years Enterprise Java Developmentg - Areas of work: - Open Source activist - DevOps evangelist - Technical and OO Trainer - Cloud and PaaS development http://www.linkedin.com/in/antonskranga
  • 3. Motivation Basic Vagrant Usage Provisioning with Cookbooks Base Images Creation Agenda
  • 4. Motivation Basic Vagrant Usage Provisioning with Cookbooks Base Images Creation Agenda
  • 5. How do you manage your Dev Env?
  • 6. Low or no automation at all Long error-prone install guides Painful maintenance or recovery Painful rollback No team collaboration Host everything natviely
  • 7. Master Image contains: - All software installed - All configuration Hosted typically in project File Server Often maintained by one Person No team collaboration Master Image
  • 8. Master Image: Problems Hard to distribute in big teams Maintenance process is manual Hard to maintain in parallel Cannot use Version Control System
  • 9. Just Enough Operating System
  • 10. - Written declaratively (just enough ruby DSL) - Repeatable - OS agnostic - Source control - Help from Community - Testable JEOS Naked OS Configuration
  • 11. V for Vagrant www.vagrantup.com Off Site www.vagrantbox.es VM Images https://github.com/opscode/bento VM Images from Chef Useful Links:
  • 12. Vagrant - Vagrant will mange VM for you - Can create whole stack of VMs - Describe VM resources in Configuration - Can put configuration in Source Control - Easy to distribute and update
  • 13. Motivation Basic Vagrant Usage Provisioning with Cookbooks Base Images Creation Agenda
  • 14. Quick start shell $ vagrant up Vagrantfile Vagrant.configure "2" do |config| config.vm.box = "vagrant-1" config.vm.box_url = "http://files.vagrantup.com/precise64.box" end
  • 15. Quick start v2 shell $ vagrant box add NAME http://files.vagrantup.com/precise64.box $ vagrant init # modify Vagrantfile until you happy $ vagrant up
  • 16. Most useful commands shell $ vagrant ssh # Connect to VM $ vagrant reload # Connect to VM $ vagrant halt # Stop VM $ vagrant destroy # delete VM $ vagrant package # Create snapshot (.box file)
  • 17. Modifying scripts Vagrantfile Vagrant.configure "2" do |config| config.vm.box = "vagrant-1" config.vm.box_url = "http://files.vagrantup.com/precise64.box" end
  • 18. Modifying scripts Vagrantfile Vagrant.configure "2" do |config| config.vm.box = "vagrant-1" config.vm.box_url = "http://files.vagrantup.com/precise64.box" config.vm.hostname = “vmhost" end
  • 19. Modifying scripts Vagrantfile Vagrant.configure "2" do |config| config.vm.box = "vagrant-1" config.vm.box_url = "http://files.vagrantup.com/precise64.box" config.vm.hostname = “vmhost" config.vm.network :forwarded_port, guest: 80, host: 1080 end

  • 24. Motivation Basic Vagrant Usage Provisioning with Cookbooks Base Images Creation Agenda
  • 25. - You declare what software you want - Chef will provision it for you - Over 1300 cookbooks Chef
  • 26. Before you start shell # install Chef plugin $ vagrant plugin install vagrant-omnibus # install Berkshelf plugin $ vagrant plugin install vagrant-berkshelf # Kind of apt-cache for Vagrant $ vagrant plugin install vagrant-cachier
  • 27. Update configuration Vagrantfile Vagrant.configure "2" do |config| config.vm.box = "vagrant-5" config.vm.box_url = "http://files.vagrantup.com/precise64.box" config.vm.hostname = “localhost" config.vm.network :forwarded_port, guest: 80, host: 1080 config.vm.synced_folder “webapp/", "/var/www“ config.omnibus.chef_version = :latest config.berkshelf.enabled = true config.cache.auto_detect = true end
  • 28. Update configuration Vagrantfile Vagrant.configure "2" do |config| config.vm.box = "vagrant-5" config.vm.box_url = "http://files.vagrantup.com/precise64.box" config.vm.hostname = “localhost" config.vm.network :forwarded_port, guest: 80, host: 1080 config.vm.synced_folder “webapp/", "/var/www“ config.omnibus.chef_version = :latest config.berkshelf.enabled = true config.cache.auto_detect = true config.vm.provision :chef_solo do |chef| chef.add_recipe “apache2“ end end
  • 29. Create berkshelf configuration Berksfile site :opscode metadata cookbook "apache2"
  • 30. Provisioning commands shell # to provision for first time just enough $ vagrant up # to restart VM $ vagrant reload --provision # to provision without restart $ vagrant provision
  • 31. Demo
  • 32. Create berkshelf configuration Berksfile site :opscode metadata cookbook 'apt' cookbook 'git' cookbook 'tomcat', git: "https://github.com/opscode-cookbooks/tomcat.git" cookbook 'maven' cookbook 'mongodb' # cookbook 'mycookbook', :path => "cookbooks/mycookbook"

  • 36. Motivation Basic Vagrant Usage Provisioning with Cookbooks Base Images Creation Agenda
  • 37. Motivation Custom project specifics OS-level patching Produce Stemcells (preinstalled images) True Infra-as-code
  • 38. Tools we need “Packer is a tool for creating identical machine images for multiple platforms…” - Off Site: packer.io - Written in Go - Must be installed to ~/pakcer “Bento is set of Packer templates for building Vagrant baseboxes” - Off Site: opscode.github.io/bento/ - Maintained by Chef
  • 39. Shell $ git clone https://github.com/opscode/bento.git $ cd bento/packer bento/packer $ packer build ubuntu-13.10-amd64.json Quick start with Packer
  • 40. Shell $ git clone https://github.com/opscode/bento.git $ cd bento/packer bento/packer $ packer build ubuntu-13.10-amd64.json Quick start with Packer
  • 41. Shell bento/packer $ packer build -only=virtualbox-iso ubuntu-13.10-amd64.json Little bit more tuning
  • 42. Shell bento/packer $ packer build -only=virtualbox -var-file=variables.json ubuntu-13.10-amd64.json Little bit more tuning variables.json { "chef_version": "latest", "mirror": "../builds/iso/" }
