    Provision
    manifest
    has provisioning
    manifest
    and it’s first time?
    yes
    start provisioning the VM
    VM is running
    vagrant up

    loads the vagrant configuration
    (share folders, port forwarding, etc)
    and starts the VM

    What is Puppet?
    

    View Slide

27. Basic concepts
    • Resources types
    • Classes, modules, templates
    • Variables, Facts and Conditionals
    • Ordering and chaining
    27
    

    View Slide

28. Built-in Resources Types
    • File
    • Exec
    • Package
    • Cron
    • Host
    • Service
    • ….

29. File example
    file { "mod_actions_conf":
    path => "/etc/apache2/mods-enabled/actions.conf",
    ensure => "link",
    target => "/etc/apache2/mods-available/actions.conf"
    }

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
    

    View Slide

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
    }

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.

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
