clear-notifications.rb

# I'm not sure if this is a good approach as I've not been working heavily with chef recently.
# However this was an approach that we used to clear notifications from cookbooks when
# using wrapper cookbooks. (worked in Chef 11)
#
# There are now probably better approaches for writing re-usable cookbooks:

## cookbook1::example.rb
#

# Here we define a template with an immediate restart
template '/some/example/template.conf' do
  source 'template.conf.erb'
  notifies :restart, 'service[example]', :immediately
end


## cookbook2::default.rb
# This is our 'wrapper' cookbook
#


include_recipe 'cookbook1::example'

# Load the template resource
our_template = resources('template[/some/example/template.conf]')

# Clear the immediate_notifications from the resource 
# (there may also be delayed_notifications, you'd need to check the code)
our_template.immediate_notifications.clear

# Then add any new notifications you may want.
our_template.notifies :restart, 'service[some_other_service]', :delayed
