Get value from hiera hash in Puppet

  • 772

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.

  1. Best Answer

    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 2nd 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.

  2. 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

    Regards.
