8. Coming up • What vagrant really is • How you can start using vagrant today (or tomorrow if you don’t want to miss the other awesome talks) • Some neat tricks • The downside of vagrant
9. The dark times
10. The dark times Word, Outlook, “nice” GUI “Compatible with work” Host Sourcecode, IDE, Stack “Development” VM
11. The dark times Sourcecode, IDE localhost Synced Folder Apache, PHP, MYSQL Remote VM Sync Sourcecode Run commands
12. The dark cloud times
13. Enter vagrant
14. Enter vagrant • Configuration: Vagrantfile • Boxes: Exported Virtual Machines + metadata • Providers: VirtualBox • Synced folders: Folders from the host which are dublicated inside the VM • Provisioners: Shell / ansible / Chef / Puppet • Plugins: Way to extend Vagrant with additional Providers, Provisioners and other stuff
15. The Vagrantfile Vagrant.configure("2") do |config| config.vm.network "private_network", ip: "10.61.6.2" config.vm.hostname = "drupal" config.vm.box = "precise64" config.vm.box_url = "http://files.vagrantup.com/precise64.box" config.vm.synced_folder "../project", "/var/www/project" config.vm.provision shell, inline: "sudo apt-get update" end
16. Configuration Vagrant.configure("2") do |config| config.vm.network "private_network", ip: "10.61.6.2" config.vm.hostname = "drupal" config.vm.box = "precise64" config.vm.box_url = "http://files.vagrantup.com/precise64.box" config.vm.synced_folder "../project", "/var/www/project" config.vm.provision shell, inline: "sudo apt-get update" end
17. The boxes Vagrant.configure("2") do |config| config.vm.network "private_network", ip: "10.61.6.2" config.vm.hostname = "drupal" config.vm.box = "precise64" config.vm.box_url = "http://files.vagrantup.com/precise64.box" config.vm.synced_folder "../project", "/var/www/project" config.vm.provision shell, inline: "sudo apt-get update" end
18. Providers
19. Synced folders Vagrant.configure("2") do |config| config.vm.network "private_network", ip: "10.61.6.2" config.vm.hostname = "drupal" config.vm.box = "precise64" config.vm.box_url = "http://files.vagrantup.com/precise64.box" config.vm.synced_folder "../project", "/var/www/project" config.vm.provision shell, inline: "sudo apt-get update" end
20. Provisioning Vagrant.configure("2") do |config| config.vm.network "private_network", ip: "10.61.6.2" config.vm.hostname = "drupal" config.vm.box = "precise64" config.vm.box_url = "http://files.vagrantup.com/precise64.box" config.vm.synced_folder "../project", "/var/www/project" config.vm.provision shell, inline: "sudo apt-get update" end
21. Shell Provisioning Vagrant.configure("2") do |config| # … config.vm.provision "shell", inline: $script config.vm.provision “shell”, path: "provision.sh" end $script = <<SCRIPT apt-get update apt-get install -y python-software-properties SCRIPT
22. Ansible Provisioning --- tasks: - name: Install nginx apt: pkg=nginx state=latest - name: Copy nginx config copy: src=nginx.conf dest=/etc/nginx/nginx.conf - name: Install mongodb pecl module command: pecl install -f mongo
23. Chef Provisioning package "nginx" do action :install end template "/etc/nginx/nginx.conf" do source "nginx.conf.erb" action :create end execute "pecl install -f mongo" do action :run end
24. Puppet Provisioning package { nginx: ensure => installed } file { "/etc/nginx/nginx.conf": source => "nginx.conf" } exec { "install mongo from pecl": command => 'pecl install -f mongo', }
25. Plugins # AWS provider $ vagrant plugin install vagrant-aws # Boxen provisioner $ vagrant plugin install ventriloquist # Manage host files $ vagrant plugin install vagrant-hostmanager # Make screenshots of your VM $ vagrant plugin install vagrant-camera # … many more!
26. A sample workflow Repository Vagrantfile Provisiong files … $ git clone git@github.com:vagrantLover/awesomeVm.git $ cd awesomeVm $ vagrant up # this may take a while $ vagrant ssh

31. Real world vagrant Yet Another Tool?
32. Real world vagrant Which provider? Which base box? Which provisioner? How should I start? How to best solve X? Do I need many vms? How should I switch? What if anything goes wrong?
