Chef - Cookbooks

Cookbooks 是 Chef 的基本工作单元，它包含与工作单元相关的所有细节，能够修改配置和任何配置为 Chef 基础设施节点的系统的状态。Cookbooks 可以执行多项任务。Cookbooks 包含有关节点所需状态的值。这是通过使用所需的外部库在 Chef 中实现的。

Cookbook（食谱）的关键组件

• Kitchen（配方）
• 元数据
• 属性
• 资源
• 模板
• 库
• 任何其他有助于创建系统的内容

创建Cookbook（食谱）

有两种方法可以动态创建Cookbook（食谱）。

• 使用 chef 命令
• 使用 knife 实用程序

使用 Chef 命令

要使用 Chef 命令创建空Cookbook（食谱），请运行以下命令。

C:\Users\vipinkumarm>chef generate cookbook <Cookbook Name> 
C:\Users\vipinkumarm>chef generate cookbook VTest

将在目录中创建名为 VTest 的Cookbook（食谱）结构，以下是该结构。

使用 Knife 实用程序

使用以下命令使用 Knife 实用程序创建Cookbook（食谱）。

C:\Users\vipinkumarm\VTest>knife cookbook create VTest2 
WARNING: No knife configuration file found 
** Creating cookbook VTest2 in C:/chef/cookbooks 
** Creating README for cookbook: VTest2 
** Creating CHANGELOG for cookbook: VTest2 
** Creating metadata for cookbook: VTest2 

以下是Cookbook（食谱）的结构。
