Puppet users - Aug 2011 - Distributing a PHP file as template fails

Hi all,

I''m trying to distribute a PHP file as a template. 
The problem I''m running into is that each variable in the PHP file is
recognized as a Puppet or ERB variable.

Take this snippet for instance:

# cat include/init.php
<?php
    $dbhost = ''<%= app_dbhost %>'';
    $dbname = ''<%= app_dbname %>'';
    $dbuser = ''<%= app_dbuser %>'';
    $dbpass = ''<%= app_dbpass %>'';
?>

When running this in Puppet I get the following error:

info: Applying configuration version ''1311757652''
err: /Stage[main]/app::Config/File[/var/www/app/include/init.php]: Could not
evaluate: Cannot find file: Invalid path ''$dbhost =
''localhost'';
$dbname = ''app_db'';
$dbuser = ''user1'';
$dbpass = ''spoofed'';'' Could not retrieve file
metadata for $dbhost = ''localhost'';
$dbname = ''app_db'';
$dbuser = ''user1'';
$dbpass = ''spoofed'';: Cannot find file: Invalid path
''$dbhost = ''localhost'';
$dbname = ''app_db'';
$dbuser = ''user1'';
$dbpass = ''spoofed'';'' at
/etc/puppet/modules/app/manifests/init.pp:64

As you can see the actual ERB parts are filled in nicely but it fails on
PHP''s variables.
I''ve tried escaping the variables and equation marks. I''ve
also renamed the php file not to end with *.erb. To no avail.

Is there a way to avoid this behavior?

Kind regards,
TomDV

That is pretty strange.  So, I tested this to be sure, and I can
manage create a file using that template just fine.

Well, it isn''t expected behaviour, so you *should* be just fine.
Obviously, though, not so much.

Can you post the actual declaration that creates the file, and the
cached YAML catalog from the node that fails?  Keep in mind that
includes all the configuration data, so if you have passwords or
whatever you might not want to do that.

Thanks,

Surely you mean (note the dash (-) ):

<?php
     $dbhost = ''<%= app_dbhost -%>'';
     $dbname = ''<%= app_dbname -%>'';
     $dbuser = ''<%= app_dbuser -%>'';
     $dbpass = ''<%= app_dbpass -%>'';
?>

I''ve always used the one without the dash.
Anyways, I do get the same error using -%>.

I''m pretty sure it does contain passwords and other sensitive
information.
Is there any other way?

The file declaration isn''t anything out of the ordinary:

file {
	"/var/www/app/include":
		ensure => directory;

	"/var/www/app/include/init.php":
		ensure => present,
		source => template ("app/init.php.erb");
}

I''ve tried Vagn Scott''s suggestion to use "<%= var
-%>" instead of  "<%= var %>" and it still dies with the
same error (below).
The file really is there and if it wasn''t it should be created anyhow.
Heck I''ve just tested with "/tmp": instead just to be sure.

If you use source, it evaluates the template, then looks for a file with 
that name.  I''ve been bitten by that many times as I change things from
files to templates.

That seemed to fix it right away.
Thanks!
