Puppet passing an array to a define to move directories

[mickael avedissian]

Hi,

I'm trying to use puppet to move some folders from one directory to another in Windows.

That being said I have a parameterized define which looks like that:

define module_name::move ($dir_name, $arg2){

$dir_origin = "c:/${dir_name}"

$dir_destination = "c:/tmp/${arg2}"

file { $dir_destination:

  ensure => 'directory',

  mode => '755',

}

exec { $backup_folder :

    command => "cmd.exe /c move $dir_origin $dir_destination",

    path => 'c:\windows\system32;c:\windows',

}

}

and I call the define as follow:

  module_name::move { 'folder_name': 

    dir_name => ['dir1','dir2','dir3'],

    arg2 => blah,

  }

when I execute this code, puppet concatenate the value of $dir_name as dir1dir2dir3 instead of running my define 3 separate times.

I would greatly appreciate getting some help on how I could reach my purpose.

Thanks,

Mike

You are passing an array (dir_name) into a single resource. Instead you
want to create three separate resources:

module_name::move { [ dir1, dir2, dir3 ]: ... }


Also, I feel compelled to point out that having verbs or actions as names
of resources is a big red warning flag, that you're doing something outside
the intended design of puppet. e.g. are you aware that your define will try
to move the directories every time you run the agent with this?

Thank you for your answer Dave.

This is the intended purpose of having the puppet agent move those folders every time it is called.

Would it be an easier (more proper) way of doing it?

Thanks,

Without knowing your actual requirements, a possible solution might
involve adding a scheduler task that will move the directories every 30
minutes. This would be much more explicit than "whenever puppet is
running", which might be much more often (when
developing/testing/deploying) or much longer (when there's a problem on
the puppet master for example).
