我发现有2种方法可以生成厨师回购，并且会因为它们的相似性而感到困惑。我想知道哪一个是推荐的方式，以及为什么厨师提供这些命令。也许他们在不同的背景下使用？

> Overview

< TODO: Enter the cookbook description here.
---
> Every Chef installation needs a Chef Repository. This is the place where cookbooks, roles, config files and other artifacts for managing systems with Chef will live. We strongly recommend storing this repository in a version control system such as Git and treat it like source code.
4a6,66
> While we prefer Git, and make this repository available via GitHub, you are welcome to download a tar or zip archive and use your favorite version control system to manage the code.
>
> Repository Directories
> ======================
>
> This repository contains several directories, and each directory contains a README file that describes what it is for in greater detail, and how to use it for managing your systems with Chef.
>
> * `certificates/` - SSL certificates generated by `rake ssl_cert` live here.
> * `config/` - Contains the Rake configuration file, `rake.rb`.
> * `cookbooks/` - Cookbooks you download or create.
> * `data_bags/` - Store data bags and items in .json in the repository.
> * `roles/` - Store roles in .rb or .json in the repository.
>
> Rake Tasks
> ==========
>
> The repository contains a `Rakefile` that includes tasks that are installed with the Chef libraries. To view the tasks available with in the repository with a brief description, run `rake -T`.
>
> The default task (`default`) is run when executing `rake` with no arguments. It will call the task `test_cookbooks`.
>
> The following tasks are not directly replaced by knife sub-commands.
>
> * `bundle_cookbook[cookbook]` - Creates cookbook tarballs in the `pkgs/` dir.
> * `install` - Calls `update`, `roles` and `upload_cookbooks` Rake tasks.
> * `ssl_cert` - Create self-signed SSL certificates in `certificates/` dir.
> * `update` - Update the repository from source control server, understands git and svn.
>
> The following tasks duplicate functionality from knife and may be removed in a future version of Chef.
>
> * `metadata` - replaced by `knife cookbook metadata -a`.
> * `new_cookbook` - replaced by `knife cookbook create`.
> * `role[role_name]` - replaced by `knife role from file`.
> * `roles` - iterates over the roles and uploads with `knife role from file`.
> * `test_cookbooks` - replaced by `knife cookbook test -a`.
> * `test_cookbook[cookbook]` - replaced by `knife cookbook test COOKBOOK`.
> * `upload_cookbooks` - replaced by `knife cookbook upload -a`.
> * `upload_cookbook[cookbook]` - replaced by `knife cookbook upload COOKBOOK`.
>
> Configuration
> =============
>
> The repository uses two configuration files.
>
> * config/rake.rb
> * .chef/knife.rb
>
> The first, `config/rake.rb` configures the Rakefile in two sections.
>
> * Constants used in the `ssl_cert` task for creating the certificates.
> * Constants that set the directory locations used in various tasks.
>
> If you use the `ssl_cert` task, change the values in the `config/rake.rb` file appropriately. These values were also used in the `new_cookbook` task, but that task is replaced by the `knife cookbook create` command which can be configured below.
>
> The second config file, `.chef/knife.rb` is a repository specific configuration file for knife. If you're using the Opscode Platform, you can download one for your organization from the management console. If you're using the Open Source Chef Server, you can generate a new one with `knife configure`. For more information about configuring Knife, see the Knife documentation.

repo生成器是许多人从GitHub克隆的旧chef-repo骨架的替代品。 app生成器有点像实验。它被设想为旧式单一回购布局和Berkshelf之间的每个食谱自己的回购布局之间的中间点。 app布局在一个git仓库中有几个密切相关的烹饪书，但仍然有多个回购整体，并专注于角色/袋上的烹饪书。
