I'm not convinced that Justin wasn't correct about this being a bug. I'm
having a similar issue
class myclass (...) {
# some extra stuff here
$file_list = [ 'a', 'b' ..., 'n' ]
file { $file_list :
ensure => 'file',
source => "puppet://modules/myclass/$title",
path => "/tmp/$title"
}
results in the "cannot alias file [a] to [/tmp/myclass]". For some reason
the resource title in my file is resolving to the class name rather than
the file name.
The solution provided above seems to change the semantics. myclass becomes
a defined type instead and the list of files is moved outside and passed in
as multiple instances are created. That's a work around.
Another would be to not use a list and simply define each file separately
in the class, that avoids having to use the $title to abstract the
definition into a single resource definition. I can do that quite easily
but in my case I have about 100 files so it makes this much less readable.
Found someone had already explained the issue here:
http://www.nico.schottelius.org/blog/puppet-name-is-not-as-expected-but-classname/.
Does anyone have an answer as to why $title in this case is resolving to
the class title rather than the resource title? Is that expected and is
there a variable I could use instead that would resolve to the name of the
resource I'm declaring rather than the class or defined type I'm declaring
it in?
I also tested this and it's not to do with the list, if I use put in each
file individually and use $title or $name it still resolves to the class
name
thanks
