hiera specifying content as template?

[Jakov Sosic]

I'm looking at this code:


define logstash::configfile(
$content = undef,
$source = undef,
$order = 10
) {

file_fragment { $name:
tag => "LS_CONFIG_${::fqdn}",
content => $content,
source => $source,
order => $order,
before => [ File_concat['ls-config'] ]
}
}


Now, I'm doing a create_resource on that one:

$logstash_configs = hiera_hash('logstash::configfiles', {})
create_resources(::Logstash::Configfile, $logstash_configs)


Problem is I cannot force a content to be an erb template....

Whatever I write in hiera, it is interpreted as text, for example:


logstash::configfiles:
'input_apache':
content: "template('adriatic/logstash/input_apache.erb')"
order: '10'


Just writes text:
template('adriatic/logstash/input_apache.erb')

into logstash config file, while I expect it to parse a template.

What am I doing wrong? Is there a way to force Hiera to pass the value
as a code and not as clear text?

Thank you

Hiera isn't running the function for you. No worries. You can change it like this:

logstash::configfiles:
  'input_apache':
    content: 'adriatic/logstash/input_apache.erb'

    order:   '10'

define logstash::configfile(
  $content = undef,
  $source = undef,
  $order = 10
) {

  file_fragment { $name:
    tag     => "LS_CONFIG_${::fqdn}",

    content => template($content),

    source  => $source,
    order   => $order,
    before  => [ File_concat['ls-config'] ]
  }
}

What you're doing with specifying both a source and a content... I'm not sure what you're going for there. Generally you use just one. Calling template on an undefined string might cause you issues, so you might have to add some error checking. I would recommend removing the source functionality from this defined type.

Thanks,

Spencer
