Un Chef Cookbook est une collection de :

• Recipes ou Recettes,
• Metadata ou Metadonnées,
• Attributes ou Attributs,
• Ressources ou Resources,
• Templates ou Gabarits.

Un Cookbook ainsi qu'une recipe :

• peut être exécuté sur un client,
• est stocké dans un Chef Infra Server.

Une Chef Recipe est :

• un fichier écrit en Ruby qui utilise le Chef DSL,
• définit l'état du client ainsi que les tâches nécessaires pour y parvenir.

Commencez par vous placer dans le répertoire /root/chef-repo/cookbooks :

root@workstation:~/chef-repo/.chef# cd ../cookbooks
root@workstation:~/chef-repo/cookbooks# 

Utilisez la commande chef generate cookbook pour créer une arborescence vierge d'un Cookbook dénommé apache2 :

root@workstation:~/chef-repo/cookbooks# chef generate cookbook apache2

Generating cookbook apache2
- Ensuring correct cookbook content
- Committing cookbook files to git

Your cookbook is ready. Type `cd apache2` to enter it.

There are several commands you can run to get started locally developing and testing your cookbook.
Type `delivery local --help` to see a full list of local testing commands.

Why not start by writing an InSpec test? Tests for the default recipe are stored at:

test/integration/default/default_test.rb

If you'd prefer to dive right in, the default recipe can be found at:

recipes/default.rb

Placez-vous dans le répertoire apache2 et constatez son contenu :

root@workstation:~/chef-repo/cookbooks# cd apache2

root@workstation:~/chef-repo/cookbooks/apache2# ls -l

drwxr-xr-x 3 root root 4096 oct.  31 10:02 test

Dans le répertoire recipes se trouve un fichier default.rb, un recipe par défaut, mais qui est actuellement vide :

root@workstation:~/chef-repo/cookbooks/apache2# cd recipes/

root@workstation:~/chef-repo/cookbooks/apache2/recipes# ls
default.rb

root@workstation:~/chef-repo/cookbooks/apache2/recipes# cat default.rb 
#
# Cookbook:: apache2
# Recipe:: default
#
# Copyright:: 2023, The Authors, All Rights Reserved.

Modifiez ce fichier avec le contenu suivant :

root@workstation:~/chef-repo/cookbooks/apache2/recipes# vi default.rb 
root@workstation:~/chef-repo/cookbooks/apache2/recipes# cat default.rb 
#
# Cookbook:: apache2
# Recipe:: default
#
# Copyright:: 2023, The Authors, All Rights Reserved.
package 'apache2'

service 'apache2' do
  action [:enable, :start]
end

template '/var/www/html/index.html' do
  source 'index.html.erb'
end

Dans ce fichier :

• package 'apache2' installe le paquet du même nom. Puisque aucune action n'est précisée, l'action par défaut est install,
• service 'apache2' active le service grâce à l'action :enable et démarre le service grâce à l'action :start,
• template '/var/www/html/index.html' crée le fichier référencé sur le client en utilisant le gabarit index.html.erb.

Puisque le Cookbook fait référence à un gabarit, nous avons besoin d'un répertoire templates dans l'arborescence de notre Cookbook :

root@workstation:~/chef-repo/cookbooks/apache2/recipes# cd ..

root@workstation:~/chef-repo/cookbooks/apache2# ls
CHANGELOG.md  kitchen.yml  metadata.rb    README.md  spec
chefignore    LICENSE      Policyfile.rb  recipes    test

root@workstation:~/chef-repo/cookbooks/apache2# mkdir templates

root@workstation:~/chef-repo/cookbooks/apache2# ls
CHANGELOG.md  kitchen.yml  metadata.rb    README.md  spec       test
chefignore    LICENSE      Policyfile.rb  recipes    templates

Créez donc le fichier index.html.erb dans le répertoire templates :

root@workstation:~/chef-repo/cookbooks/apache2# vi templates/index.html.erb
root@workstation:~/chef-repo/cookbooks/apache2# cat templates/index.html.erb
<html>
  <body>
    <h1>Hello World!</h1>
  </body>
</html>

Le Cookbook est maintenant terminé. Il convient donc de le téléverser vers le Chef Infra Server en utilisant la commande knife cookbook upload et en spécifiant le nom du Cookbook apache2 :

root@workstation:~/chef-repo/cookbooks# knife cookbook upload apache2
Uploading apache2      [0.1.0]
Uploaded 1 cookbook.

Il est possible de visualiser les sous-commandes disponibles de la commande knife cookbook :

root@workstation:~/chef-repo/cookbooks# knife cookbook --help
FATAL: Cannot find subcommand for: 'cookbook --help'
Available cookbook subcommands: (for details, knife SUB-COMMAND --help)

** COOKBOOK COMMANDS **
knife cookbook bulk delete REGEX (options)
knife cookbook delete COOKBOOK VERSION (options)
knife cookbook download COOKBOOK [VERSION] (options)
knife cookbook list (options)
knife cookbook metadata COOKBOOK (options)
knife cookbook metadata from file FILE (options)
knife cookbook show COOKBOOK [VERSION] [PART] [FILENAME] (options)
knife cookbook upload [COOKBOOKS...] (options)
