Re: Base directory with File

[Mark Roggenkamp]

Actually, I think a definition will work.

define file_with_base($base_dir) {

  file {"$base_dir/$name":

    ...

  }

}

file_with_base($bars:

  base_dir => $base_dir

}

I didn't think about the $name coming from an array used when creating the file_with_base definition. I was only thinking about the parameters specified in the define, which probably comes from me continuing to think of it like a function which is wrong.

Hi all,

I'd like to specify a base_directory and a list of directories (as variables that may be pulled via hiera later) that will be created under that base directory.

base_dir = "/home/base"

bars = ["a", "b", "c"]

bars will be used to create the folders under base and also part of the information going into building a template so I don't want to store them as ["$base_dir/a", "$base_dir/b", "$base_dir/c"]. 

What's the best way to create the bar directories under the base_dir? I'd love to just give File the bars array and specify the base_dir as a property. Should I make a prepend function that would prepend base_dir to each bar and then pass that to File? 

I tried a definition but then to loop I have to generate a single loop-able structure to call the definition with that contains both bars and base_dir. I looked at create_resources but that seems like it'd force me to make more things variables than I wanted and duplicate more than I would like.

Thanks,

Mark

If you don't want to use a define here you can use the way how the regsubst
function works on arrays: It will apply the substition on all elements and
will then return an array with the same length. So this does also work:

$base_dir = '/home/base'
$bars = ['a', 'b', 'c']

# prefix all bars with base_dir
$dirs = regsubst($bars, '(.*)', "${base_dir}/\\1")

file { $dirs:
ensure => directory,
}

Even better. Thank you, sir.
