Get value from hiera hash in Puppet

Question

I have this structure in my hiera file that create some rules in my smb.conf.

samba::shares:
  PDF:
    - comment = "PDF"
    - path = /home/smb/pdf
    - browseable = yes
    - hide dot files = yes
    - read only = no
    - public = yes
    - writable = yes
    - create mode = 0775
    - printable = no
  Partage:
   - comment= "Partage"
   - path = /home/smb/Partage
   - browseable = yes
   - hide dot files = yes
   - read only = no
   - public = yes
   - writable = yes
   - create mode = 0775
   - printable = no

I want to access the path of each share for create automatically the folder with the right persmissions.

I tried many solutions with hiera_hash() but I can not find the right setting. :

define create_folder{
  # I want to loop on PDF, Partage, etc. and extract path 
  # for each one (/home/smb/pdf, /home/smb/Partage, etc.).
  $path = hiera_hash('path') 

  file{"$path":
    path => $path,
    ensure => diretory,
    owner => "smb",
    group => "smb",
    require => File["/home/smb/"],
    mode => '775',
  }
}

Can you help me please ?

Regards.

This is an application for the create_resources method.

In your case, you would not fetch the hash from inside the resource, but from outside:

# puppet/site.pp
create_resources(create_folder, hiera_hash('samba::shares', {}))

# puppet/modules/...
define create_folder(
  $comment,
  $path,
  $browseable,
  $hide_dot_files,
  $read_only,
  $public,
  $writable,
  $create mode,
  $printable,
){
  file{"$path":
    path => $path,
    ensure => diretory,
    owner => "smb",
    group => "smb",
    require => File["/home/smb/"],
    mode => '775',
  }
}

The 2^nd argument to hiera_hash is a default value. I prefer to always keep an empty Hash there in order to be able to load the resource on all machines, even if only certain machines have the values defined.

Note that the keys in your YAML files would have to be renamed: Puppet won't like keys with spaces in them. I replaced spaces with underscores there. – François Beausoleil Apr 24 '15 at 14:01
See [How to instantiate multiple instances of the same resource using Hiera](https://serverfault.com/questions/648584/how-to-instantiate-multiple-instances-of-the-same-resource-using-hiera/648613#648613) for my own question on the subject, and [Puppet hiera and create_resource issue](http://stackoverflow.com/questions/24911151/puppet-hiera-and-create-resource-issue) for the definitive answer. – François Beausoleil Apr 24 '15 at 14:02
Thank you, I have found another solution but I keep yours for future developments. ;) Have a nice day. – Oyabi Apr 24 '15 at 14:39

Finally, I add one script who's run everty time puppet run :

#!/bin/bash
folders=($(cat /etc/samba/smb.conf | grep path | cut -d" "  -f3))

for folder in "${folders[@]}" ; do
  if [ ! -d "$folder" ]; then
    mkdir -p "$dossier"
    chown -R smb:smb "$folder"
    chmod -R 775 "$folder"
  fi
done
