Hi Chef users email distribution list,
An update on this item: if I set load_default_config to false my template renders correctly. Therefore, I conclude that the observed behavior is a consequence of Chef’s resource cloning.
The only change from the pastebin below is that I tried defining and explicitly passing in the variable that I have manipulated in my wrapper logic:
nagios_contactgroups = Nagios.instance.contactgroups
begin
t = resources(:template => “#{node[‘nagios’][‘config_dir’]}/contacts.cfg”)
t.source "contacts.cfg.erb"
t.cookbook "sm-nagios"
t.variables(:nagios_contactgroups => Nagios.instance.contactgroups)
#rescue Chef::Exceptions::ResourceNotFound
Chef::Log.warn “could not find template #{node[‘nagios’][‘config_dir’]/contacts.cfg to modify”
End
Can anyone shed light on why the cloned resource is superseding my attempt to open back up the object and re-render it?
I am going to turn off load_default_config and copy in all of the logic, adding in my logic to manipulate the arrays – I’d love to understand where I went wrong with the wrapper method here though, I won’t be able to use wrappers if the behavior isn’t intelligible to me.
Any assistance anyone can offer is greatly appreciated.
Thanks all,
Joseph Hammerman

Subject: [chef] Using the wrapper cookbook development method to remove the pager duty contact from the Nagios Cookbook
Hi Chef users email distribution list,
I’m trying to use the wrapper development method to change the values written out for the contactgroups in the Nagios cookbook. As you all may or may not know, this cookbook makes heavy use of definitions, resources and LWRPs. Within the users_helper.rb definition file, the following block of code exists:
def return_user_contacts
contacts = []
# add base contacts from nagios_users data bag
@users.each do |s|
contacts << s['id']
end
# add pagerduty user if enabled
contacts << 'pagerduty' unless @node['nagios']['pagerduty']['key'].empty?
contacts
end
I personally like to have an email only contactgroup.
I attempted this (which manipulates the arrays correctly):
My reasoning was that I have updated the information in the class members that are referenced when the file is rendered, so if I rerender the file, if the arrays contain the correct members, the file should be rendered with the content that I desire.
However, during the Chef run, I see this output:
Recipe: sm-nagios::_load_default_config
- nagios_contactgroup[admins] action create (up to date)
- nagios_contactgroup[admins-sms] action create (up to date)
I’m thinking I could be encountering the resource cloning that Chef does?
Can anyone assist in better understanding the method / process I should be using here?
Thanks all,
Joseph Hammerman
