This has been moved into the official Chef docs:

12.5 style custom resources

This is by far the most recommended way of writing resources for all users. There are two gotchas which we're working through:

1. For helper functions that you used to write in your provider code or used to mixin to your provider code, you have to use an action_class do ... end block.

Prerequisites

You'll need to have a system running that is accessible through a DNS record. It should have access to the public Habitat depot, https://app.habitat.sh so it can download the required packages.

You'll need to register an OAuth application for GitHub. You need the client ID and client secret that are created for the application later in this guide. Your system needs to have access to https://github.com so that it can authenticate.

Your system also needs to have an FQDN that can be resolved, for example depot.example.com. This will be used in your OAuth application's "Authorization Callback URL." For this example, use http://depot.example.com/#/sign-in. The /#/sign-in is required.

Notifications from Resources "Bubble Up"

Release in Chef 12.9.41 via PR #4741 core chef now has a feature which has been available in Poise for awhile, which is that notifications from within resources will now notify resources in outer run contexts. This means you can write a recipe with a service resource and send a notification to it from a resource that you write.

Notifications will bubble up from arbitrarily nested resources, so users that write resources that wrap resources which wrap your resource will still find the service resource in your default recipe.

At the same time the resources collection #find() and #lookup methods and the more commonly-used DSL method resources("service[ntpd]") has been changed to also match

Freezer cgroup FTW

In a terminal start a server.

$ python -m SimpleHTTPServer 8000

In another terminal set up the cgroups freezer.
