Supermarket Belongs to the Community

Supermarket belongs to the community. While Chef has the responsibility to keep it running and be stewards of its functionality, what it does and how it works is driven by the community. The chef/supermarket repository will continue to be where development of the Supermarket application takes place. Come be part of shaping the direction of Supermarket by opening issues and pull requests or by joining us on the Chef Mailing List.

notifying-action

Build Status

This Chef cookbook simplifies creating resource providers that enclose other resources and need to
notify their subscribers based on the notifications received from all or a subset of these
enclosed resources. This is based on the approach of wrapping all sub-resources used in a resource
in a sub-run-context and examining the results of running that sub-run-context. The implementation
is influenced by the following sources:

Opscode Community page: http://community.opscode.com/cookbooks/notifying-action.

Example

Suppose you are implementing a resource that installs a service
and creates a configuration file for it. Then, you want to restart the service if either a new
version was installed, or the configuration file changed.

In your providers/package_and_conf.rb you would have:

action :install do
  notifying_action_wrapper do
    package 'my_service' do
      action :install
    end

    template '/etc/my_service/config.yml'
      source 'config.yml.erb'
    end
  end
end

You will then be able to use this LWRP in recipes as follows:

my_cookbook_package_and_conf 'my_service' do
  action :install
  notifies :restart, 'service[my_service]', :immediately
end

service 'my_service' do
  action :nothing
end
