====================================================
Additional puppet notes after books and presentation
====================================================

At some point, I'm going to have to consolidate all the notes into
one document; but, just to keep the new shit segregted from the old
shit...

Taking the free puppet courses available at https://puppetlabs.com/learn/library

Classes:
========

Just ran through the exercise.  Interestingly, didn't have to create a site.pp
file.  Just include the module at the end of the module definition: ::

    class motd {
      file { '/etc/motd':
        ensure  => file,
        owner   => 'root',
        group   => 'root', 
        content => 'Hellow, world!  Puppet is AWESOME!!',
      }
    }
    include motd
    
Then run ``puppet apply motd.pp`` and it works...

Autoloading:
============

${module}->lib directory contains custom facts and custom resource types?

$confdir = 

    *   /etc/puppet (open source)
    *   /etc/puppetlabs (puppet enterprise)

``puppet config print modulepath`` to display the modulepath.

autoloading = puppet run, -> catalog compile -> find/compile the modules.

Relationship:
=============

before: Causes a resource to be applied before the target resource

require: Causes a resource to be applied after the target resource

notify: Causes the notified resource to refresh if the notifying resource 
changes

subscribe: subscribing resource will refresh if the target resource changes.

chto gets applied first::

    class chto {
        before => some_other
    }

chto gets applied after::

    chass chto {
        require => some_other
    }

Hiera:
======

Hiera is for providing config data in the form of variables

ENCs are for providing node configuration.

Facter IDs system information such as OS, IP, etc. Sends facts to puppet
