Puppet users - Jul 2012 - create_resources function and puppet enc

Hi,

I am trying to create multiple users using puppet. I have created a ENC and 
trying to use class wrapped defined types with create_resources function. 
For some reason things are falling apart. I would really appreciate some 
help on these

Here are the details about my classes and configuration

There are at least three kinds of problems there:

   1. resource names in resource references should be capitalized.  For 
   example:
   
   "require => [ User[$uname] ]"
   
   2. you are trying to pass parameters (jeckman, saga, sandipb, and 
   vartika) to non-parametrized class ''users''.
   3. your class ''users'' is passing a previously-undefined
variable $users
   to the create_resources function

The quickest fix to get this working would probably be to add a parameter 
$users to class users, and to update your ENC to wrap the individual user 
hashes (''jeckman'', etc.) in an outer hash
''users'':

classes:
  users:
    users:
      jeckman:
        comment: Jack
        gid: 100

[...]

That says class "users" should be assigned to the node, and the value
of
its parameter "users" should be the specified hash of hashes.

With that said, I have to add that you probably should not be fiddling with 
an ENC as you first start out.  Small sites rarely get much advantage from 
an ENC, and few indeed are the sites that will benefit from a custom-built 
one.  Additionally, I generally advise everyone to avoid parametrized 
classes.  They introduce pitfalls that newbies generally are not equipped 
to recognize or appreciate.

If you want to define data, such as user properties, outside your Puppet 
manifests then do look into adding Hiera to your puppetmaster.  That''s 
Puppetlabs chosen direction.  With hiera you use a Puppet function to load 
your data instead of feeding it in via a parameter.  (Puppet 3 will allow 
you to combine class parameters with data lookup, but it''s not quite
ready
for release yet.)
