8. va•grant (ˈveɪ grənt) Noun: ! a person without a settled home or regular work who wanders from place to place and lives by begging 8
9. • 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, Ansible, Chef and other tools 9 What is Vagrant?
10. 10 example of a Vagrantfile
11. 11 # /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
12. 12 $ cd /path/to/my/project ! $ vagrant up ! $ vagrant ssh Running it
13. 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 13
14. 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 14
15. Multi Machines Ability to replicate your system's architecture http://docs.vagrantup.com/v2/multi-machine/index.html 15
16. 16 # /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
17. 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 17
18. Debugging ! $ set VAGRANT_LOG=debug $ vagrant up ... http://docs.vagrantup.com/v2/debugging.html 18
19. Providers 19
20. and others… https://github.com/mitchellh/vagrant/wiki/Available-Vagrant-Plugins#providers 20
21. Customize the Provider 21
22. 22 # /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
23. Provision 23
24. 24 Shell scripts
25. http://puppetlabs.com/ http://docs.puppetlabs.com/references/latest/type.html 25
26. • IT automation software • Language inspired by Nagios • Declarative language 26 What is Puppet?
27. Basic concepts • Resources types • Classes, modules, templates • Variables, Facts and Conditionals • Ordering and chaining 27
28. Built-in Resources Types • File • Exec • Package • Cron • Host • Service • …. 28
29. File example file { "mod_actions_conf": path => "/etc/apache2/mods-enabled/actions.conf", ensure => "link", target => "/etc/apache2/mods-available/actions.conf" } 29
30. Classes • Named blocks • Defining a class does not evaluate the code • Declaring evaluates the code (include) 30 Modules • module name == folder name • specific folder structure
31. Class example class my_class { notify {"This actually did something":} } ! include my_class 31
32. Ordering & chaining • No loading order • before and require • notify and subscribe • arrow chaining ( -> to require and ~> to notify) 32
33. 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 } } 33
34. http://www.ansible.com/home http://docs.ansible.com/ 34
35. • IT natural automation language • Agentless 35 What is Ansible?
36. Basic concepts • Inventory • Playbook • Tasks • Roles • Handlers • Modules 36
37. File example - name: Install custom repo yum: name=http://mirror.webtatic.com/yum/el6/latest.rpm state=present sudo: yes ! - name: Install common packages yum: name={{ item }} state=present sudo: yes with_items: - htop - vim 37
38. Inventory 38 Modules • module name == folder name • specific folder structure # /path/to/hosts [vagrant] 10.0.30.5 host1 ansible_ssh_port=5555 ansible_ssh_host=10.0.30.5
39. Class example class my_class { notify {"This actually did something":} } ! include my_class 39
40. Ordering & chaining • No loading order • before and require • notify and subscribe • arrow chaining ( -> to require and ~> to notify) 40
41. 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 } } 41
42. 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 42
43. let’s get started 43
44. 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. 44
45. 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 45
46. Librarian Puppet • Helps manage the modules • https://github.com/rodjek/librarian-puppet 46
