#file-exsistance-test-on-puppet-master

TODO: Add error checking and possibly tests.

Installation

put this script in your puppet module under:

  $your_module/lib/puppet/parser/exists.rb

Usage

You can use this to determine if a file exsists on the puppet master. This is extreamly useful if you need to access templates or files from a hierarchy.

  i.e. $your_module/templates/domains/domain1.com/database.yml
       vs.
       $your_module/templates/domains/domain2.com/database.yml

Here is an example of how you would call it in a manifest file.

   if exists("/etc/puppet/environments/${environment}/modules/$your_module/templates/${domain}/${environment}/database.yml"){
    file { "database.yml":
      path    => "/data/${application}/shared/config/database.yml",
      owner   => 'deploy',
      group   => 'deploy',
      content => template("$your_module/${domain}/${environment}/database.yml"),
    }
  }

Here, you can see that the file method will only be called if the template exists. Otherwise it will ignore the template.
