1. Vagrant, Puppet, Fabric and Magento Sitting in a Tree
2. Vagrant, Puppet, Fabric and Magento Sitting in a Tree
3. Let’s build a virtual development environment
4. Let’s build a virtual development environment(!)
5. …Why?
6. Lots of reasons “It works on my machine” Improve set up time Simplify deployment Fun Consistency Testing infrastructure Less tech support
7. Vagrant
8. Step 1:
 Install
10. Step 2:
 Choose an OS
11. Vagrant Cloud is your friend
14. Step 3: Get it going
15. vagrant init chef/centos-6.5
16. vagrant up
17. vagrant ssh
18. [vagrant@localhost ~]$
19. Step 4:
 Networking
20. Port forwarding
21. localhost:8008
 ➝ vagrant:80
22. config.vm.network “forwarded_port", guest: 80, host: 8008
23. I dislike port numbers
24. Private IP adresses
25. 10.3.118.121
26. config.vm.network "private_network", 
 ip: "10.3.118.121"

27. Much better
28. SSH for Git?
29. [vagrant@localhost ~]$ ssh -t git@bitbucket.org Permission denied (publickey).
30. Use your own SSH key
31. config.ssh.forward_agent = true
32. [vagrant@localhost ~]$ ssh -t git@bitbucket.org logged in as maxbucknell. ! You can use git or hg to connect to Bitbucket. Shell access is disabled. Connection to bitbucket.org closed.
33. Easy
34. Step 5:
 Provisioning
35. Shell Provisioning
36. To Install puppet
37. sudo rpm -ivh [puppet repository] sudo yum install -y puppet
38. config.vm.provision "shell", path: "shell_provision.sh"
39. Puppet

40. Say what you want
41. Let Puppet work out the rest
42. Everything is a resource
43. Lots of resource types
45. Most useful:
 Package, File, Service, Exec

46. Package
 Installing software

47. /** * Nginx * Version 1.4.4 */ ! package { 'nginx': ensure => '1.4.4-1.el6.ngx', notify => File['/etc/nginx/nginx.conf'], }
48. Providers
 Where the software comes from.
 yum, pip, gem, etc.
49. /** * Compass */ ! package { 'compass': provider => 'gem', ensure => '0.12.7', }
50. File
 Copy something to a place;
 perfect for config files
51. /** * Nginx configuration, optimised for Magento. */ ! file { '/etc/nginx/nginx.conf': ensure => 'present', source => '/vagrant/server_config/etc/nginx/ nginx.conf', notify => Service['nginx'], }
52. Service
 Start, stop and restart services

53. service { 'nginx': ensure => 'running', }
54. Exec
 Run a command

55. /** * Composer */ ! exec { 'curl -sS https://getcomposer.org/installer | php': cwd => '/usr/local/bin', creates => '/usr/local/bin/composer.phar', path => '/usr/local/bin:/usr/bin', }
56. Metaparameters Or, how Puppet doesn’t go from top to bottom
57. Problem: Puppet tries to start PHP-FPM before it installs it
58. Solution: Metaparameters
59. package { 'php-fpm': ensure => 'installed', notify => Service['php-fpm'], }
60. Do this thing…
61. …Then try that thing again
62. Tell Vagrant about Puppet
63. config.vm.provision "puppet" do |puppet| puppet.manifest_file = "base.pp" end
64. Fabric

65. SSH scripts for deployment
66. Python
 It’s definitely worth adding another runtime
67. Fabric (& Python)
 crash course
68. @task def clean_up(): """Clear out installed files""" local('/bin/rm -rf %s' % magento_root) local('/bin/rm -rf %s/vendor' % project_root)
69. [vagrant@localhost ~]$ fab clean_up
70. @task
 def get_database_dump(): """Get a database dump from the server.""" db_filename = random_filename('sql') db_location = os.path.join(config['tmp_dir'], db_filename) with cd(config['magento_root']): run('%s db:dump -f %s --strip="@development"' % (config['magerun'], db_location)) get(remote_path=db_location, local_path='/tmp') with lcd(magento_root): local('n98-magerun.phar db:import %s' % '/tmp/' + db_filename)

71. How to run fabric
72. vagrant ssh --command="fab get_db_dump"
73. #! /bin/bash ! vagrant ssh --command="fab $1"
74. Done
75. Next steps
76. Vanilla Magento
77. Vagrant Share
78. Deployment
