Puppet multi_epp source function

The multi_epp puppet function allows you to list multiple Embedded Puppet (EPP) template files and use the first one that exists.

The most common usage is to declare multiple files, most specific to least specific, and the values that should be passed to the template for use inside it.

class ssh::config {

  file { '/etc/ssh/sshd_config':
    ensure  => present,
    mode    => '0600',
    content => multi_epp( [
                            "ssh/${::fqdn}.epp",
                            "ssh/${::domain}.epp",
                            'ssh/default_sshdconfig.epp',
                          ], {
                                'port'          => 22222,
                                'ListenAddress' => '0.0.0.0',
                          }),
  }

}

It's worth noting that the template file names must be called as an array of multiple files. While this is a little unwieldy it's required due to the way Puppet handles repeated parameters and anything following them in an invocation.

Supported versions

This function was written using the Puppet 4 function API and so will not run on Puppet 3 unless the future parser is enabled.
