[Puppet Users] get a hash from multiple levels(with the same keys but different values) with hiera

Hello,

I have this configuration:

File: comon.yaml

SSH:
 ConfigFolder: "/etc/ssh/"
 sshd_config:
  Protocol: "1,2"
  SyslogFacility: "AUTHPRIV"
  *PermitRootLogin*: "no"
  PasswordAuthentication: "yes"
  ChallengeResponseAuthentication: "no"
  GSSAPIAuthentication: "yes"
  GSSAPICleanupCredentials: "yes"
  UsePAM: "yes"
  *ClientAliveInterval*: "100"

File test_env.yaml [same keys as in comon.yaml but with different values] :

SSH
 sshd_config:
  *PermitRootLogin*: "yes"
  *ClientAliveInterval*: "80"


File hiera.yaml:

---
:backend:
  - yaml
:hierarchy:
  - %{environment}
  - comon

:yaml:
# datadir is empty here, so hiera uses its defaults:
# - /var/lib/hiera on *nix
# - %CommonAppData%\PuppetLabs\hiera\var on Windows
# When specifying a datadir, make sure the directory exists.
  :datadir: /etc/puppet/hieradata

In puppet code:
 $ssh_data = hiera_hash(''SSH'')
 $sshd_config = $ssh_data(''sshd_config'')


If a node has %{environment} == test_env I want to retrieve a hash 
(in sshd_config) like:

  Protocol: "1,2"
  SyslogFacility: "AUTHPRIV"
*  PermitRootLogin: "yes"*
  PasswordAuthentication: "yes"
  ChallengeResponseAuthentication: "no"
  GSSAPIAuthentication: "yes"
  GSSAPICleanupCredentials: "yes"
  UsePAM: "yes"
*  ClientAliveInterval: "80"*

if environment != test_env then I want to retrieve :

  Protocol: "1,2"
  SyslogFacility: "AUTHPRIV"
  *PermitRootLogin: "no"*
  PasswordAuthentication: "yes"
  ChallengeResponseAuthentication: "no"
  GSSAPIAuthentication: "yes"
  GSSAPICleanupCredentials: "yes"
  UsePAM: "yes"
  *ClientAliveInterval: "100"*



In my setup for the first care i get (it reads only test_env.yaml - that is 
not what I want):
  *PermitRootLogin*: "yes"
  *ClientAliveInterval*: "80"

and for the second (reads only comon.yaml - is ok) :

  Protocol: "1,2"
  SyslogFacility: "AUTHPRIV"
  *PermitRootLogin*: "no"
  PasswordAuthentication: "yes"
  ChallengeResponseAuthentication: "no"
  GSSAPIAuthentication: "yes"
  GSSAPICleanupCredentials: "yes"
  UsePAM: "yes"
  *ClientAliveInterval*: "100"

Is this possible with my Hiera definition?


Thank you,
Alex

[Puppet Users] Re: get a hash from multiple levels(with the same keys but different values) with hiera

the hiera() call bails out the first time it finds an answer. Assuming 
you''re calling something like hiera(''sshd_config''),
you''re getting that
first answer and nothing else. You need to replace the hiera() call with 
hiera_hash(), which will merge a hash at all levels of the hierarchy, 
preferring more specific answers.

Re: [Puppet Users] get a hash from multiple levels(with the same keys but different values) with hiera

The reason it doesn''t work is that hiera_hash() only does a shallow
merge,
not a deep merge of the hashes within the hash.

There should be support for deep merging in hiera 1.2.0-rc1 though:
