I'm looking at building a simple ensurable custom type that itself
uses Puppet resources to manage a group of files and users. Because
of the multi-dimensional data structures I'm dealing with, dropping
into Ruby seems to be the best way to go. I have a feeling that using
file resources is the right way to do this but I'm having trouble with
providers. First, I'm just trying to get it to run without exceptions
using the following type and provider:
require 'puppet/type'
Puppet::Type.newtype(:foobar) do
@doc = "foobar"
newparam(:name, :namevar => true) do
desc "foobar name."
end
ensurable do
self.defaultvalues
defaultto :present
end
end
require 'puppet/resource'
require 'puppet/resource/catalog'
require 'puppet/type'
require 'puppet/type/file'
require 'puppet/type/user'
Puppet::Type.type(:foobar).provide(:posix) do
desc "foobar"
defaultfor :operatingsystem => :debian
def create
Puppet.notice :create
catalog = Puppet::Resource::Catalog.new
catalog.add_resource Puppet::Resource.new(:user, "demo", :ensure => :absent)
catalog.apply
end
def destroy
Puppet.warn "DevStructure users should never need to be destroyed."
end
def exists?
Puppet.notice :exists?
false
end
end
The error is: "err: Got an uncaught exception of type NoMethodError:
undefined method `provider' for #<Puppet::Resource:0x7f1f8f724b78>"
(Full output below.)
The probem seems to be in setting/inheriting the default provider for
the user resource. How does the main catalog set/inherit default
providers? Is this use of resources advisable/supported or would I be
best off not using a catalog or not using resources altogether?
Thanks for any help you can provide,
Richard
