Puppet

Puppet programs are called ‘manifests’, and they use the .pp file extension.

The place to find and share modules for Puppet: http://forge.puppetlabs.com/ :: Home | Puppet Module Repository | Puppet Labs

The Facter is a lightweight library for retrieving simple operating system facts, like operating system, linux distribution, or MAC address. It’s standalone utility (bundled in Vagrant with Puppet) that can be invoked by typing facter.

Great example of Development Environment:

Learning:

# /root/learning-manifests/break_ssh.pp
package { 'openssh-server':
  ensure => present,
  before => File['/etc/ssh/sshd_config'],
}

file { '/etc/ssh/sshd_config':
  ensure => file,
  mode   => 600,
  source => '/root/learning-manifests/sshd_config',
}

service { 'sshd':
  ensure     => running,
  enable     => true,
  hasrestart => true,
  hasstatus  => true,
  subscribe  => File['/etc/ssh/sshd_config'],
}

Symlinking /var/www to /vagrant does what you wanted without having to dive into httpd.conf:

file { ‘/var/www’: ensure => link, target => ‘/vagrant’, force => true, require => Package[‘apache2’] }

Learning

Good example of using command/unless Puppet pattern: Magento-Vagrant-Puppet.

Why .erb files? Ruby Template Files - Because they can contain variables. ERB is part of the Ruby standard library. You do not need to install any other software to use it. An Introduction to ERB Templating Using Puppet Templates — Documentation — Puppet Labs

Variables in JSON files: pperezrubio/puppet-vagrant-template JSON Parser is in stdlib module.

I don’t understand why this Vagrant plug-in(vagrant-puppetconf) is made. I allows you to update some puppet variables directy from Vagrantfile. I think that this can be achieved without extra module - with Facter, as shown in this example. It’s documented here.

The main idea and logic was taken from: dirkaholic/vagrant-php-dev-box benlumley/VagrantPuppet · GitHub

I could need a following modules.

My devbox

  • site.pp: first file that the Puppet parses
  • templates.pp: defines all template classes
  • nodes.pp: defines all the nodes. All nodes must have a name equal to their hostname. If you create a node named default, the node configuration for default will be used if no other node matches are found. nodes

Problems & solutions

Message: No LSB modules are available

This message is issued by Facter. It simply states that there are no LSB facts available. It’s simple to fix - not really a fix, because it’s intentionally missing from the base install. Anyway, there is an easy way to enable LSB facts via Puppet)

Vagrant Startup Warning: No LSB modules are available.

There is no way to fix this ‘noise’. The message is from lsb_release command in terminal.

Testing the Puppet

When in VM (don’t forget sudo):

puppet apply --noop --modulepath=../modules/ site.pp
puppet apply --noop --debug --verbose --modulepath=../modules/ site.pp

--Noop switch is here to forbid any real operation on system.

In Vagrant, this is the executed line:

cd /tmp/vagrant-puppet/manifests &&
FACTER__ip_main='192.168.7.70' FACTER__ip_node='192.168.7.71'
puppet apply --modulepath '/tmp/vagrant-puppet/modules-0' /tmp/vagrant-puppet/manifests/site.pp
