    http://docs.puppetlabs.com/references/latest/type  【puppet 资源类型】

    Every resource has a type, a title, and a set of attributes:

    general form of a resource declaration is:

        The resource type, in lower-case
        An opening curly brace
        The title, which is a string
        A colon
        Optionally, any number of attribute and value pairs, each of which consists of:
            An attribute name, which is a bare word
            A => (arrow, fat comma, or hash rocket)
            A value, which can be any data type, depending on what the attribute requires
            A trailing comma (note that the comma is optional after the final attribute/value pair)
        Optionally, a semicolon, followed by another title, colon, and attribute block
        A closing curly brace



    core of the Puppet language is declaring resources;
    Groups of resources can be organized into classes;

    catalog will be in memory as a Ruby object, transmitted as JSON, and persisted to disk as YAML;

    case $operatingsystem {
          centos, redhat: { $service_name = 'ntpd' }
          debian, ubuntu: { $service_name = 'ntp' }
        }
    
        package { 'ntp':
          ensure => installed,
        }
    
        service { 'ntp':
          name      => $service_name,
          ensure    => running,
          enable    => true,
          subscribe => File['ntp.conf'],
        }
    
        file { 'ntp.conf':
          path    => '/etc/ntp.conf',
          ensure  => file,
          require => Package['ntp'],
          source  => "puppet:///modules/ntp/ntp.conf",
          # This source file would be located on the puppet master at
          # /etc/puppetlabs/puppet/modules/ntp/files/ntp.conf (in Puppet Enterprise)
          # or
          # /etc/puppet/modules/ntp/files/ntp.conf (in open source Puppet)
        }
