Instance Method Details

#client(name) ⇒ Chef::Client?

Find a client at the given name

#client_key ⇒ String

The path to the insecure Chef Zero private key on disk. Because Chef requires the path to a file instead of the contents of the key (why), this method dynamically writes the ChefZero::PRIVATE_KEY to disk and then returns that path.
