This module is a small wrapper around the Chef 'knife' command line utility. It would be awesome if this module used the Chef server API, but this module is not that awesome.
Some things worth knowing about this module:
-
Return vaules
All commands return the output of the knife command.
-
Logging
If you wish to log output, you should do so via the 'callback' attribute. See Shell::Carapace for more details.
-
Exceptions
If a knife command fails, an exception is thrown.
