How to create a cookbook ?

Once we installed the Chef workstation, we need to create the directory called Cookbooks, which will have as many cookbooks with recipes.

1. Create a directory called cookbooks

   mkdir cookbooks

2. To create a cookbook, go inside the cookbooks directory and generate the cookbook

   cd cookbooks

   Generating the cookbook,

   chef generate cookbook <cookbook-name>

   

   Output- Cookbook created successfully.

   

3. To create the recipes we have to go inside created cookbook directory and generate the cookbook.

   cd cookbook-name

   Generating the recipe,

   chef generate recipe <recipe-name>

   

   Output- Recipe created successfully.

   

4. To build recipes go to the cookbooks directory. Open the recipe using vi command.

   vi cookbook-name/recipes/<recipe-name.rb>

5. Now create a file using the Chef recipe, by editing the recipe.

   

   • Press i to enter text in file.

   • Press esc, and type :wq to save and exit the file.

6. To check Ruby scripting, with output syntax Ok or Not,

   chef exec ruby -c cookbook-name/recipes/<recipe-name.rb>

   

7. Execute the recipe

   chef-client -zr "recipe[cookbook-name::recipe-name]"

   

   

   Output- myfile is created with the content.
