Vagrantfile with Puppet config example

Following is a sample Vagrantfile that will start 4 vagrant box and assigning each an public ipaddress and puppet class, where we can define what all need to deployed on there box. Over here I have provided one vagrant_box image, but if you want you can provide each host with different vagrant_box_image.



$cat Vagrantfile


VAGRANTFILE_API_VERSION = "2"
Vagrant.configure(VAGRANTFILE_API_VERSION) do |config|

  config.vm.define "vg2" do |vg2|
    vg2.vm.box = "my_vagrant_image"
    vg2.vm.hostname = "vg2"
    vg2.vm.network "public_network", :bridge => 'wlan0', :ip => "192.168.0.32"
  end

  config.vm.define "vg3" do |vg3|
    vg3.vm.box = "my_vagrant_image"
    vg3.vm.hostname = "vg3"
    vg3.vm.network "public_network", :bridge => 'wlan0', :ip => "192.168.0.33"
  end


  config.vm.define "vg4" do |vg4|
    vg4.vm.box = "my_vagrant_image.box"
    vg4.vm.hostname = "vg4"
    vg4.vm.network "public_network", :bridge => 'wlan0', :ip => "192.168.0.34"
  end

  config.vm.define "vg5" do |vg5|
    vg5.vm.box = "my_vagrant_image.box"
    vg5.vm.hostname = "vg5"
    vg5.vm.network "public_network", :bridge => 'wlan0', :ip => "192.168.0.35"
  end

  config.vm.provision :puppet do |puppet|
    puppet.manifests_path = "puppet/manifests"
    puppet.manifest_file  = "default.pp"
    puppet.options = ['--verbose']
  end



explanation of puppet class:

Note: even if we have lots of different vagrant box defined in a single Vagrantfile, we just need to have only one puppet class, that should be enough for all of the vagrant box.

    puppet.manifests_path = "puppet/manifests"

The above line says what is the path where we have the manifests file. [ Relative to the location where we have the Vagrantfile. ]

     puppet.manifest_file  = "default.pp"

The above line says which is the manifest file.


Example of the manifest.pp:

$ cat puppet/manifests/default.pp
Exec { path => [ "/bin/", "/sbin/" , "/usr/bin/", "/usr/sbin/" ] }

class system-update {
  exec { 'apt-get update':
    command => 'apt-get update',
  }

  $sysPackages = [ "build-essential" ]
  package { $sysPackages:
    ensure => "installed",
    require => Exec['apt-get update'],
  }
}

class apache {
  package { "apache2":
    ensure  => present,
    require => Class["system-update"],
  }

  service { "apache2":
    ensure  => "running",
    require => Package["apache2"],
  }

}

class iotop {
  package { "iotop":
    ensure  => present,
    require => Class["system-update"],
  }
}



include apache
include system-update
include iotop


NOTE: you have to use the include lines for deploying those package to these instance. Note: Example the iotop class also have a require => Class, pointing to the system-update class. If you don't what to have the system-update class run at your system then, you can comment these line [with # ] and comment the following include line too.
