Method: Chef::ApiClient::Registration#run

Defined in:
lib/chef/api_client/registration.rb

#run ⇒ Object

Runs the client registration process, including creating the client on the chef-server and writing its private key to disk. – If client creation fails with a 5xx, it is retried up to 5 times. These retries are on top of the retries with randomized exponential backoff built in to Chef::ServerAPI. The retries here are a workaround for failures caused by resource contention in Hosted Chef when creating a very large number of clients simultaneously, (e.g., spinning up 100s of ec2 nodes at once). Future improvements to the affected component should make these retries unnecessary.
