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. Because Chef Zero runs in memory, it's super fast and lightweight. This makes it perfect for testing against a "real" Chef Server without mocking the entire Internet. Installation ------------ This server can be installed as a Ruby Gem. $ gem install chef-zero If you're using bundler, add `chef-zero` as a development dependency: ```ruby group :development do gem 'chef-zero' end ``` Or in a `.gemspec` ```ruby s.add_development_dependency 'chef-zero' ``` You can also clone the source repository and install it using `rake install`. Usage ----- One of chef-zero's primary uses is as a small test server for people writing and testing clients. Here's a simple example of starting it up: ```ruby require 'chef_zero/server' server = ChefZero::Server.new(port: 4000) server.start ``` This will create a server instance in the foreground. To stop the server: ```ruby server.stop ``` This is great for debugging and logging requests, but you'll probably want to run this in the background so you have full control of your thread. To run Chef Zero in the background, simply issue the `start_background` command: ```ruby require 'chef_zero/server' server = ChefZero::Server.new(port: 4000) server.start_background ``` You can stop the server the same way: ```ruby server.stop ``` ### Valid Options You may currently pass the following options to the initializer: - `host` - the host to run on (Default: '127.0.0.1') - `port` - the port to run on (Default: 8889) - `debug` - run in debug mode to see all requests and responses (Default: false) CLI (Command Line) ----------------- If you don't want to use Chef Zero as a library, you can simply start an instance with the included `chef-zero` executable: $ chef-zero Note, this will run in the foreground. You now have a fully functional (empty) Chef Server running. To try it out, go into the `chef-zero/playground` directory and run `knife`. It will behave the same as a normal Chef Server, and all normal knife commands will work (show, list, delete, from file, upload, download, diff ...). For example, with +knife-essentials+ (or Chef 11) you can upload everything in the repo: chef-zero/playground> knife upload .

Since Chef Zero does no authentication, any `.pem` file will do. The client just needs something to sign requests with (which will be ignored on the server). Even though it's ignored, the `.pem` must still be a valid format. Now, stop the Chef Zero server and all the data is gone! Run `chef-zero --help` to see a list of the supported flags and options: ```text Usage: chef-zero [ARGS] -H, --host HOST Host to bind to (default: 127.0.0.1) -p, --port PORT Port to listen on --[no-]generate-keys Whether to generate actual keys or fake it (faster). Default: false. -l, --log-level LEVEL Set the output log level -h, --help Show this message --version Show version ```
