It IS intended to be simple, Chef 11+ compliant, easy to run and fast to start. It is NOT intended to be secure, scalable, performant or persistent. It does NO input validation, authentication or authorization (it will not throw a 400, 401 or 403). It does not save data, and will start up empty each time you start it. -Description ------------ -Chef Zero is a simple, easy-install, in-memory Chef server that can be useful -for Chef Client testing and chef-solo-like tasks that require a full Chef -Server.
