Chef - 菜譜

菜譜是 Chef 的基本工作單元，它包含所有與工作單元相關的細節，能夠修改 Chef 基礎架構上配置為節點的任何系統的配置和狀態。菜譜可以執行多個任務。菜譜包含關於節點所需狀態的值。這在 Chef 中是透過使用所需的外部庫實現的。

菜譜的關鍵元件

• 菜譜
• 元資料
• 屬性
• 資源
• 模板
• 庫
• 任何其他有助於建立系統的內容

建立菜譜

有兩種方法可以動態建立菜譜。

• 使用 chef 命令
• 使用 knife 實用程式

使用 Chef 命令

要使用 Chef 命令建立空菜譜，請執行以下命令。

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

名為 VTest 的菜譜結構將被建立在目錄中，其結構如下。

使用 Knife 實用程式

使用以下命令使用 knife 實用程式建立菜譜。

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 

菜譜的結構如下。
