#register(client_name = node_name, config = Chef::Config) ⇒ Chef::ServerAPI
This method is part of a private API. You should avoid using this method if possible, as it may be removed or be changed in the future.
Determine our private key and set up the connection to the Chef server.
Skips registration and fires the skipping_registration
event if
Chef::Config.client_key is unspecified or already exists.
If Chef::Config.client_key does not exist, we register the client with the Chef server and fire the registration_start and registration_completed events.

Standard rest object for talking to the Chef Server
FIXME: Can we drop this and only use the rest_clean object? Did I add rest_clean only out of some cant-break-a-minor-version paranoia?

A rest object with validate_utf8 set to false. This will not throw exceptions on non-UTF8 strings in JSON but will sanitize them so that e.g. POSTs will never fail. Cannot be configured on a request-by-request basis, so we carry around another rest object for it.

#run ⇒ Object
Do a full run for this Chef::Client.
Locks the run while doing its job.
Fires run_start before doing anything and fires run_completed or run_failed when finished. Also notifies client listeners of run_started at the beginning of Compile, and run_completed_successfully or run_failed when all is complete.
Phase 1: Setup
Gets information about the system and the run we are doing.
- Run ohai to collect system information.
- Register / connect to the Chef server (unless in solo mode).
- Retrieve the node (or create a new one).
- Merge in json_attribs, Chef::Config.environment, and override_run_list.
Phase 2: Compile
Decides what we plan to converge by compiling recipes.
- Sync required cookbooks to the local cache.
- Load libraries from all cookbooks.
- Load attributes from all cookbooks.
- Load LWRPs from all cookbooks.
- Load resource definitions from all cookbooks.
- Load recipes in the run list.
- Load recipes from the command line.
Phase 3: Converge
Brings the system up to date.
- Converge the resources built from recipes in Phase 2.
- Save the node.
- Reboot if we were asked to.
