Puppet users - Nov 2011 - Fetching puppet files and templates from Maven

How would one go about fetching a template from Maven? For example, the
normal way of using a file resource for an application config file might be:

file { "/etc/app/app.xml":
    mode    => "0755",
    owner   => "appuser",
    group   => "appuser",
    content => template("app/app.xml.erb"), # retrieved from
modules/app/templates/app.xml
    notify  => Service[app],
    require => Package[app];
}

However, what if app.xml.erb is in a separate Maven repository on some
other server? How would you go about retrieving and evaluating the template?

How might you go about this for a normal file, i.e. instead of source =>
"puppet://..." ?

I guess you could use an exec resource for a normal file but probably not
for a template since Puppet needs to evaluate the code in the template file.

Thoughts?

What you need is a custom function that can retrieve the file and
process it as a template. I would look at the inline_template function
and create something like remote_template where you retrieve the file
from a remote location and process it.

Thanks,

Ah, cool. So something like this if I understand custom functions:

module Puppet::Parser::Functions
  newfunction(:remote_template, :url) do |args|
    Puppet::Parser::Functions.autoloader.loadall

    # TODO fetch the template from its remote source
    # TODO and save locally as a temporary template file
    # TODO referenced by the variable temp_template

    function_template(temp_template)
  end
end
