[chef] Re: How to add/modify the default template provided by cookbook but without editing the given template?

Ohai!

maybe this is what you are looking for:

https://github.com/opscode-cookbooks/chef_handler 

AFAICT the chef_handler LWRP takes care of managing your handlers. I don't know whether it would write through to the client.rb though. See the example here:

chef_gem "chef-handler-mail"
gem "chef-handler-mail"

chef_handler "MailHandler" do
   source 'chef/handler/mail'
   arguments :to_address => "root"
   action :nothing
end.run_action(:enable)

I guess you would have to create a separate cookbook (e.g. 'my-handlers') where you define the handlers as shown above in the default recipe.

HTH,

Torben

P.S.:  It would be cool if you could manage the handlers via a databag - has someone done this already?

Ohai chefs!

e.g.

Following is the snippet from the 'chef-client::config' recipe.

    template "#{node["chef_client"]["conf_dir"]}/client.rb" do
      source "client.rb.erb"
      owner "root"
      group root_group
      mode 0644
      variables :chef_node_name => chef_node_name
      notifies :create, "ruby_block[reload_client_config]"
    end

Its values can be overridden to customize it.
But what if I to edit the template itself or how to put the modified template in my cookbook to get rendered instead of editing the default template provided by the cookbook itself?

e.g.
 
Now I want to use  `https://github.com/kisoku/chef-handler-mail`.
For this to work beside downloading, uploading to chef-server and using in roles/other-recipes, I've to add

    #Using /etc/chef/config.rb

    require 'rubygems'
    require 'chef/handler/mail'

    mail_handler = MailHandler.new
    report_handlers << mail_handler
    exception_handlers << mail_handler

to the template itself.

Now how to just override the default template provided by chef-client at `templates/default/client.rb.erb` only with the additional chef-handler-mail code appended to it?
