[Puppet Users] How to use create_resources with a define

I have not used the create_resources function before, looks like
exactly what I need indeed.

How do I use it with a define.. my ENC outputs something like:

  nfs_mounts:
        - mount_point: "/data"
          mount_device:
"fas3319-518.example.com:/vol/onecrddb_data/test"
        - mount_point: "/data2"
          mount_device:
"fas3319-518.example.com:/vol/onecrddb_data/test2"


Then in my manifests:


class gu_misc {
...

  define mount_nfs_shares(
        $mount_point,
        $mount_device) {

        file{ $mout_point: ensure => directory }
        mount { $mount_point:
            device => $mount_device,
            name => $mount_point,
            require => File[$mount_point],
        }
    }

    create_resources(gu_misc::mount_nfs_shares, $nfs_mounts)

}

I get error: undefined method `[]'' for nil:NilClass


Thanks a lot,
Mohamed.

Re: [Puppet Users] How to use create_resources with a define

I would do something like this:
** In your YAML file
---
nfs_mounts
  mount1:
    mount_point    : ''/data''
    mount_device : "fas3319-518.example.com:/vol/onecrddb_data/test"
  mount2:
    mount_point     : "/data2"
     mount_device : "fas3319-518.example.com:/vol/onecrddb_data/test2"

** In site.pp

$nfs_mounts = hiera_hash(''nfs_mounts'')
 create_resources(gu_misc::mount_nfs_shares, $nfs_mounts)

I''m pretty new to puppet, but a (more experienced) coworker and I just
ran into something nearly identical with hiera/YAML a couple days ago.

I believe the issue is that your ENC is outputting an array, not a hash,
and create_resources works on hashes.

If you can get your ENC to output a hash, you''ll likely have better
luck.

Re: [Puppet Users] How to use create_resources with a define

Thanks guys. The hash thing sounds like my problem... but I still get
the same error!!

undefined method `[]'' for nil:NilClass at
/etc/puppet/environments/production_ml623/modules/gu_misc/manifests/init.pp:81
on node onecrddb-test-1

where line 81 is:

    create_resources(mount_nfs_shares, $nfs_mounts)

I tried, with same error:

create_resources(gu_misc::mount_nfs_shares, $nfs_mounts)


What else am I missing ?

Thanks a lot,
Mohamed.

Re: [Puppet Users] How to use create_resources with a define

Ooops... My yaml was wrong.. it said:

nfs_mounts:
       -  mount1:
            mount_point: "/data"
            mount_device:
"fas3319-518.example.com:/vol/onecrddb_data/test"
       -  mount2:
            mount_point: "/data2"
            mount_device:
"fas3319-518.example.com:/vol/onecrddb_data/test2"


Instead of:

nfs_mounts:
        mount1:
            mount_point: "/data"
            mount_device:
"fas3319-518.example.com:/vol/onecrddb_data/test"
        mount2:
            mount_point: "/data2"
            mount_device:
"fas3319-518.example.com:/vol/onecrddb_data/test2"

Thanks all,
Mohamed.
