3. What to expect from this talk 1)Vagrant overview 2)What's New: 1.5 and 1.6 3)Provisioner Tasting: Ansible, Puppet and Chef 4)ProTips 5)Useful Resources
5. Why Vagrant?
6. “It works on my machine” - every developer, ever.
7. Why Vagrant? • Reproducible and portable development environment • Enables easier code collaboration • Backend env tests / benchmark • Automation Tools learning and testing
9. Some Terms • Boxes • Provider / Provisioner • Host / Guest • Vagrantfile • Synced Folder
10. The simplest thing that does something Vagrant.configure("2") do |config| config.vm.box = "hashicorp/precise64" config.vm.provision "shell", inline: "echo Hello World!" end
12. Commands • up • reload • provision • suspend • resume • destroy [ --provision ] [ --provision ]
13. DEMO
14. Another Vagrantfile Vagrant.configure("2") do |config| config.vm.box = "hashicorp/precise64" config.vm.network :private_network, ip: "192.168.33.101" config.vm.provision "ansible" do |ansible| ansible.playbook = "playbook.yml" end config.vm.synced_folder "./", "/vagrant", :nfs => true end
15. What's New
16. Recent new features Vagrant 1.5 • Vagrant Cloud / boxes 2.0 • Vagrant Share • Rsync • SMB Vagrant 1.6 • Global Status and Control • Windows as Guest • Docker Provider • Post-up Message
17. Vagrant Cloud (1.5)
18. Vagrant Share (1.5)
19. Post-up message (1.6)
20. Global status and control (1.6)
22. 1. Ansible • Tasks, Playbooks, Roles • Tasks are defined with YAML • 3rd most used • Modules Directory: Ansible Galaxy • Requires installation of Ansible in the Host
23. 1.1 A Task - name: Install Nginx apt: pkg=nginx state=latest
24. 1.1 A Task - name: Install Nginx apt: pkg=nginx state=latest - name: Install PHP Packages apt: pkg={{ item }} state=latest with_items: - php5-fpm - php5-cli
25. 1.2 A Playbook # playbook.yml --- - hosts: all sudo: true tasks: - name: Update apt-cache apt: update_cache=yes - name: Install Nginx and php5-fpm apt: pkg={{ item }} state=latest with_items: - nginx - php5-fpm
26. 1.3 A Role . ├── playbook.yml └── roles ├── init │ └── tasks │ └── main.yml └── nginxphp ├── tasks │ └── main.yml └── templates └── vhost.tpl #playbook.yml --- - hosts: all sudo: true vars: doc_root: /vagrant/web roles: - init - nginxphp
27. 1.4 Vagrantfile Vagrant.configure("2") do |config| config.vm.box = "hashicorp/precise64" config.vm.provision "ansible" do |ansible| ansible.playbook = "playbook.yml" end end
29. 2. Puppet (puppet-apply) • Resources, Manifests, Modules • Non-sequential execution order • Custom language based on Ruby • 1st most used • Modules Directory: Puppet Forge
30. 2.1 A Resource package { 'nginx': ensure => 'installed' }
31. 2.1 A Resource package { 'nginx': ensure => 'installed' } package { ['php5-fpm', 'php5-cli']: ensure => 'installed' }
32. 2.2 A Manifest # manifests/default.pp exec { 'apt-get update': command => 'apt-get update' } package { ['nginx', 'php5-fpm']: ensure => 'installed', require => Exec['apt-get update'] }
33. 2.3 A Module . ├── manifests │ └── default.pp └── modules └── nginxphp ├── manifests │ └── init.pp └── templates └── vhost.erb # manifests/default.pp exec { 'apt-get update': command => 'apt-get update', before => Class['nginxphp'], } class { 'nginxphp': doc_root => '/vagrant/web', }
34. 2.4 Vagrantfile Vagrant.configure("2") do |config| config.vm.box = "hashicorp/precise64" config.vm.provision :puppet do |puppet| puppet.module_path = "modules" end end
36. 3. Chef (chef_solo) • Resources, Recipes, Cookbooks • Resources defined with Ruby • 2nd most used, 1st with Ruby devs • Modules Directory: Cookbooks • Complex but very powerful
37. 3.1 A Resource apt_package "nginx" do action :install end
38. 3.1 A Resource apt_package "nginx" do action :install end ["nginx", "php5-fpm"].each do |p| apt_package p do action :install end end
39. 3.2 A Recipe # cookbooks/main/recipes/default.rb execute "apt-get update" do command "apt-get update" end ["nginx", "php5-fpm"].each do |p| apt_package p do action :install end end
40. 3.3 A Cookbook . └── cookbooks ├── main │ └── recipes │ └── default.rb └── nginxphp ├── recipes │ └── default.rb └── templates └── default └── vhost.erb # cookbooks/main/recipes/default.rb execute "apt-get update" do command "apt-get update" end include_recipe 'nginxphp'
41. 3.4 Vagrantfile Vagrant.configure("2") do |config| config.vm.box = "hashicorp/precise64" config.vm.provision "chef_solo" do |chef| chef.add_recipe "main" end end
44. 6.1 Debugging • Unknown Vagrant error – Use VirtualBox / Vmware GUI • Unknown Provisioner error – Increase provisioner verbosity • Not working as expected – Login, fix, automate
45. 6.2 Sync Folder Performance • Synchronization has a cost • Framework cache/logs – Too much writing operations on disk – We don't need this in our synced folder
49. Useful Resources
52. Examples on GitHub • Basic examples • Comparing Provisioners – PHP5 + Nginx example https://github.com/erikaheidi/nomad-vagrant
