Chef - 菜谱

菜谱是 Chef 的基本工作单元，它包含所有与工作单元相关的细节，能够修改 Chef 基础架构上配置为节点的任何系统的配置和状态。菜谱可以执行多个任务。菜谱包含关于节点所需状态的值。这在 Chef 中是通过使用所需的外部库实现的。

菜谱的关键组件

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

创建菜谱

有两种方法可以动态创建菜谱。

• 使用 chef 命令
• 使用 knife 实用程序

使用 Chef 命令

要使用 Chef 命令创建空菜谱，请运行以下命令。

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

名为 VTest 的菜谱结构将被创建在目录中，其结构如下。

使用 Knife 实用程序

使用以下命令使用 knife 实用程序创建菜谱。

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 

菜谱的结构如下。
