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: }

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", ... }

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