Hi Puppet users,
I've been using Hiera's deep merge feature on class parameters for months,
however when I try to pair it with the create_resources function things get
ugly.
Situation:
I want to deploy a set of Unix users on all my machines. They have standard
rights by default and get access to the wheel group on a per-server basis
depending on their needs.
In my module I have:
manifests/user.pp
> class environment::users ( $users = hiera_hash('user_list') {
> create_resources('user', $users)
> }
>
And in Hiera:
hiera/common.yaml
> ---
> user_list:
> foo:
> ensure: present
> uid: '1001'
> gid: '1001'
> groups: []
> comment: Doctor Foo
> bar:
> ensure: present
> uid: '1002'
> gid: '1002'
> groups: []
> comment: Mister Bar
>
*It works great so far.* All my users are deployed on all machines.
Now I try to add the user foo to the wheel group on dev_server:
hiera/dev_server.example.com.yaml
> ---
> user_list:
> foo:
> groups: wheel
>
Since the deeper
<http://docs.puppetlabs.com/hiera/1/lookup_types.html#deep-merging-in-hiera--120>
merge bahavior is enabled this should merge my user list just fine.
But... BANG! It all breaks apart:
> *Error: Could not retrieve catalog from remote server: Error 400 on
> SERVER: Must pass uid to User[foo] on node *
>
> *dev_server.example.comWarning: Not using cache on failed catalogError:
> Could not retrieve catalog; skipping run*
>
However, if I query Hiera from the shell, it returns the expected user hash:
$ hiera --hash user_list ::clientcert=dev_server.example.com
>
> {"foo"=>
> {"ensure"=>"present",
> "gid"=>"1001",
> "groups"=>"wheel",
> "comment"=>"Mister Foo",
> "uid"=>"1001"},
> "bar"=>
> {"ensure"=>"present",
> "gid"=>"1002",
> "groups"=>"[]",
> "comment"=>"Doctor Bar",
> "uid"=>"1002"}}
>
Corruption? Madness? Did I miss something crucial when reading through the
documentation?
Thank you in advance for the hints :)
