ZendCon Europe | Building a LAMP environment with Vagrant & Puppet

Do you work in more than one project or with more than one person in or per project? If yes, this workshop is for you.

One of the tasks where developers usually spend lots of time is in the configuration of the project development environment. What if you configure it by running a simple command? Without to have to hurry about product versions, without install anything in your machine?

This workshop will introduce you to Vagrant and Puppet. You will build your own dev environment step-by-step and at the end you will know how to share it and how you can reproduce and customize it for other projects.

8. http://www.vagrantup.com/ !8
9. va•grant (ˈveɪ grənt) Noun: ! a person without a settled home or regular work who wanders from place to place and lives by begging !9
10. • Manage virtual machines (such as Virtual Box, VMware, AWS, and others) • Define the configuration in code with a single file • Provision the VM with Shell scripts, Puppet, Chef and other tools !10 What is Vagrant?
11. !11 example of a Vagrantfile
12. !12 # /path/to/Vagrantfile ! Vagrant.configure("2") do |config| ! # define base box config.vm.box = "precise64" config.vm.box_url = "http://files.vagrantup.com/precise64.box" ! # port forwarding config.vm.network :forwarded_port, guest: 80, host: 8080 ! # setup a private network with a static IP Address config.vm.network :private_network, ip: "10.5.0.2" ! # sharing folders config.vm.synced_folder ".", "/vagrant" ! end
13. !13 $ cd /path/to/my/project ! $ vagrant up ! $ vagrant ssh Running it
14. Workflow of vagrant up Vagrantfile Provision manifest has provisioning manifest and it’s first time? yes start provisioning the VM VM is running vagrant up downloads the box if needed, loads the vagrant configuration (share folders, port forwarding, etc) and starts the VM !14
15. vagrant init vagrant up vagrant halt vagrant reload vagrant provision vagrant package vagrant plugin vagrant ssh vagrant ssh-config vagrant suspend vagrant resume vagrant destroy vagrant commands !15
16. Multi Machines Ability to replicate your system's architecture http://docs.vagrantup.com/v2/multi-machine/index.html !16
17. !17 # /path/to/Vagrantfile ! Vagrant.configure("2") do |config| ! config.vm.define "web" do |web| web.vm.box = "apache" # ... end ! config.vm.define "db" do |db| db.vm.box = "mysql" # ... end ! end
18. Plugins https://github.com/mitchellh/vagrant/wiki/Available-Vagrant-Plugins vagrant plugin install vagrant-example-plugin vagrant plugin list vagrant plugin uninstall vagrant-example-plugin Installing a plugin Uninstalling a plugin Listing installed plugin !18
19. Debugging ! $ set VAGRANT_LOG=debug $ vagrant up ... http://docs.vagrantup.com/v2/debugging.html !19
20. Providers !20
21. and others… https://github.com/mitchellh/vagrant/wiki/Available-Vagrant-Plugins#providers !21
22. Customize the Provider !22
23. !23 # /path/to/Vagrantfile ! Vagrant.configure("2") do |config| ! config.vm.provider :virtualbox do |vb| vb.customize [ "modifyvm", :id, '--chipset', 'ich9', '--natdnshostresolver1', 'on', '--memory', 1024 ] end ! end
24. Provision !24
25. !25 Shell scripts Ansible
26. http://puppetlabs.com/ http://docs.puppetlabs.com/references/latest/type.html !26
27. • IT automation software • Language inspired by Nagios • Declarative language !27 What is Puppet?
28. Basic concepts • Resources types • Classes, modules, templates • Variables, Facts and Conditionals • Ordering and chaining !28
29. Built-in Resources Types • File • Exec • Package • Cron • Host • Service • …. !29
30. File example file { "mod_actions_conf": path => "/etc/apache2/mods-enabled/actions.conf", ensure => "link", target => "/etc/apache2/mods-available/actions.conf" } !30
31. Classes • Named blocks • Defining a class does not evaluate the code • Declaring evaluates the code (include) !31 Modules • module name == folder name • specific folder structure
32. Class example class my_class { notify {"This actually did something":} } ! include my_class !32
33. Ordering & chaining • No loading order • before and require • notify and subscribe • arrow chaining ( -> to require and ~> to notify) !33
34. Ordering example class apt { exec { "apt-update": unless => "test -f /home/vagrant/.apt-update", command => "apt-get update -y", path => ["/bin", "/usr/bin"], notify => File["/home/vagrant/.apt-update"], } ! file { "/home/vagrant/.apt-update": ensure => file, force => true } } !34
35. What are we going to build? ! • Provider: Virtual box 4.3 • OS: Ubuntu 12.04 x64 ! • PHP 5.4 • Apache 2.2 • MySQL 5.5 !35
36. let’s get started !36
37. Distributing and sharing • Use (D)VCS (Git, SVN, Mercurial, etc.) ! • Add the Vagrantfile and provisioning files (puppet, chef, shell scripts, etc) to your repository ! • Add .vagrant folder to your repository ignore file or your global ignore file. !37
38. Tips and Tricks • When working in multiple projects use port forwarding and networks carefully • Avoid port collision by adding auto_correct: true for each port forwarding • Use --debug on your provision options when something is wrong • Have guest additions always up to date • Improve share folders performance by enabling nfs (is not available on windows) • If you are using Puppet modules, don't forget to add the module dependencies as well !38
39. Librarian Puppet • Helps manage the modules • https://github.com/rodjek/librarian-puppet !39
