 Hi list,

 When declaring multiple resources at once with an array like this:

 Is there a way to access the current array element so as to pass this

 foo and bar with a parameter value bar?
 
 
 I think what you want is to use $name. it corresponds to the resource
 name that is currently being worked on.
 
 file { [ foo, bar ]: path = /blah/${name}.txt, ... }
 

Close, but no cigar.

You need to wrap the file in a define like:

define my_file() {
  file { $name:
owner = $name,
mode  = 640,
  }
}

Then you can just use

$array = [ ... ]
my_file { $array: }

Regards,
Felix

RE: [Puppet Users] use current array element when declaring multiple resources using an array

2010-11-10 Thread Matthew Black 
What you are looking for is a loop which does not exist in puppet, except
for templates. 

I've never tried it but I've speculated it could be possible to create a
manifest template and then use puppet to generate that manifest file in a
similar fashion you are looking to do.

Subject: [Puppet Users] use current array element when declaring multiple
resources using an array

Hi list,

When declaring multiple resources at once with an array like this:

file { [ foo, bar ]: ... }

Is there a way to access the current array element so as to pass this
value as a parameter? So the foo resource has a parameter value
foo and bar with a parameter value bar?

This is a broken example showing that Puppet looks to be evaluating
owner = $array1 in it's entirety (and perhaps only taking the first
element for a File resource?):

  $array1 = [ /tmp/one, /tmp/two, /tmp/three ]
  file { $array1:
ensure = present,
owner = $array1,
  }

err: /Stage[main]/Test/File[/tmp/three]: Could not evaluate: Could not
find user /tmp/one
err: /Stage[main]/Test/File[/tmp/two]: Could not evaluate: Could not
find user /tmp/one
err: /Stage[main]/Test/File[/tmp/one]: Could not evaluate: Could not
find user /tmp/one

What I want to see is:

err: /Stage[main]/Test/File[/tmp/three]: Could not evaluate: Could not
find user /tmp/three
err: /Stage[main]/Test/File[/tmp/two]: Could not evaluate: Could not
find user /tmp/two
err: /Stage[main]/Test/File[/tmp/one]: Could not evaluate: Could not
find user /tmp/one

Is there an equivalent of Perl's $_ variable? Perhaps with some
inline_template Ruby magic? This would make some config I'm trying to
write a great deal more concise.
