Chef itself is built from many moving parts, including knife, Chef client, Chef server, cookbooks, and nodes. Here, we will talk about cookbooks and how they can be efficiently managed using Berkshelf.

When you are using Chef to manage all your servers and network equipments, you should first create cookbooks and appropriate recipes.

On all your remote servers, you’ll use chef-client to execute the recipes from the cookbook.

In this tutorial, we’ll explain how to use knife command to create and manage your Chef cookbooks.
The knife command can be executed from any Chef workstation.

1. Create New Chef Cookbook

To create a cookbook, use “knife cookbook create” command as shown below. The following will create a cookbook with name thegeekstuff.

For the above command, knife command creates a separate directory called “thegeekstuff” under ~/chef-repo/cookbooks as shown below.

The following is the cookbook folder structure.

2. Create New Cookbook with Custom Options

The metadata.rb file under the cookbook directory will have the following default values.

The above values will be used to generate header in any of the .rb files that you create under this cookbook.

While creating a cookbook, the best practice is to pass the following options.

In the above command:

• -C is the copyright holder name. You can also use –copyright option.
• -m is the email address. You can also use –email option.
• -I is the license type. This will automatically add the appropriate license notice in the files that you create under this cookbook. The following are the valid license types you can use. In this example, we are using gplv3, which will add the GPL v3 license notice in the header. You can also use –license option.
  • apachev2 – This will use Apache v2.0
  • gplv2 – This option is for GPL v2
  • gplv3 – For GPL v3
  • mit – For MIT
• none – This option will add this notice to the files: “Proprietary – All Rights Reserved”
• -r option will define the format for the README files in this cookbook. Use “rdoc” option for Ruby docs, and “md” for markdown. Instead of -r you can also use –readme-format
• -o (or –cookbook-path) – This option is used when you want to specify a different directory path where you want the cookbooks to be created. In the above example, we are not using this option.

3. Upload Cookbook to Chef Server

The following “knife cookbook upload” command will upload the cookbook that we created above to the Chef server.

As we see, since this is the first version of this cookbook, it is showing the version number as 0.1.0.

When you have multiple cookbooks that has multiple versions, you can upload all of your cookbooks using option -a.

In the following example, we have 4 cookbooks, and the latest version of all these cookbooks are getting uploaded.

The following command will not only upload “thegeekstuff” cookbook, but it will also upload all the dependent cookbooks.

4. Lock a Cookbook from Future Edits

When you don’t want anybody else to be modifying a particular cookbook version, use the –freeze option.

In the following example, after this command, nobody can upload the 2.1.0 version of “thegeekstuff” cookbook anymore. You have to create a new version.

If you are trying to upload the same version, you’ll get the following error message.

For some reason, if you want to edit and upload a cookbook that is frozen, use the –force option.

When you are uploading lot of cookbooks that are big, you can use the –concurrency option. By default this is set to 10. In the following example, we are setting the concurrency to 15 while uploading the cookbook.

5. Get a List of ALL Cookbooks

The following “knife cookbook list” command will display all the cookbooks that are available on your Chef server. The 2nd column in the following output is the latest version of that cookbook.

To view how many versions are available for the cookbooks, use the -a option which will display ALL versions. You can also use –all option.

The -w option will display all the cookbook versions along with their corresponding URIs as shown below. You can also use –with-uri option. You can combine -a option with -w as shown below.

6. Delete a Single Cookbook

Use the following “knife cookbook delete” command, which will delete the cookbook. In this example, we are deleting “dev-db” cookbook.

The -p option will delete the cookbook, and permanently purge the cookbook from the Chef server. Use this option with caution.

7. Delete One (or All) Versions of a Cookbook

When a cookbook has multiple versions, the delete command will display all the versions and prompt the user to choose either one of the version, or all versions as shown below.

In the above example, I choose 1 to delete “thegeekstuff” cookbook with version 2.1.0

You can also specify the version number to delete directly in the command lien as shown below.

If you want to delete ALL the version of a specific cookbook, use option -a as shown below. You can also use –all instead of -a.

8. Delete Multiple Cookbooks using Bulk Delete

In the following example, we are using “knife cookbook bulk delete” command to delete multiple cookbooks at the same time. You can pass regular-expressions as parameter to this command.

The following example will delete all the cookbooks that start with “dev-“.

This this example, we have three cookbooks that matches the given regular expression. But, each of these cookbooks have multiple versions. So, this command will delete all the version of these three cookbooks.

9. Download Cookbook from Chef Server

When you have chef-client installed on multiple machine, and when you want to download a cookbook that someone has modified on your client, then use the “knife cookbook download” command as shown below.

The following command will download the “dev-db” cookbook from the Chef server to your local machine.

The cookbook will be downloaded to the current directory. The downloaded cookbook folder will also have the version number appended at the end.

When you are trying to download a cookbook that has multiple versions, it will prompt you to choose a specific version.

In the following example, since “thegeekstuff” cookbook has multiple versions, it will display the following option, and you can choose one from the list.

You can also pass the cookbook version number in the command-line as shown below, to directly download that particular version to your local machine.

If you just want to download the latest version of a cookbook without having to specify a version number, use -N option (or –latest option) as shown bnelow.

When a version of the cookbook that you are downloading has already been downloaded before, you’ll get the following error message.

In that case, use the -f option (or –force) to download the cookbook and overwrite the local directory with the version that was downloaded from the Chef server.

Instead of downloading it under the current directory, you can also specify a download directory using -d option (or –dir option).

The following command will download “thegeekstuff” version 2.1.0 cookbook to ~/tmp/download directory.

10. Generate Cookbook Metadata

You can generate metadata file for your cookbook using “knife cookbook metadata” command as shown below. The following command will generate the metadata.rb for all the cookbooks.

If you want to generate metadata only for a specific cookbook, then specify the direct path of the metadata.rb file for that particular cookbook using the “from file” option as shown below.

The following command will generate metadata for “thegeekstuff” cookbook using the given metadata.rb file.

11. View Cookbook Details

You can view the details of a cookbook using “knife cookbook show” command.

When you don’t specify a version number for a cookbook, the show command will display list of all the version numbers available for the given cookbook.

But when you specify a version number, this will display lot more information about the cookbook as shown below.

The default output of the above command will display lot of information.

You can also specify a section number to the show command as shown below, which will display only that particular section in the show command output.

12. Validate Cookbook Syntax

The following “knife cookbook test” command will do a syntax check validation on the cookbook files.

In the following example, we have an error in “thegeekstuff” cookbook. As you see in the last line, it says that the method “author” in the metadata.rb file is undefined and not recognized by Chef.

Once the syntax error is fixed, we’ll see the following output indicating that our cookbook passed all the syntax verification.

If you get this “WARNING: DEPRECATED: Please use ChefSpec or Rubocop to syntax-check cookbooks.” in the above output, you can ignore it.

In order to make Chef node communicate with Chef server, you need to set up Chef client on the node.

Chef Client

This is one of the key components of Chef node, which retrieves the cookbooks from the Chef server and executes them on the node. It is also known as the Chef provisioner.

Here, we will use Vagrant to manage VM. Vagrant can also be configured with the provisioner such as Shell script, Chef and Puppet to get VM into a desired state. In our case, we will use Vagrant to manage VMs using VirtualBox and Chef client as a provisioner.

Download Cookbook From Chef Server For Windows 10

Step 1 − Download and install VirtualBox from https://www.virtualbox.org/wiki/downlod

Step 2 − Download and install Vagrant at http://downloads.vagrantup.com

Step 3 − Install Vagrant Omnibus plugin to enable Vagrant to install Chef client on the VM.

Creating and Booting Virtual

Step 1 − We can download the required Vagrant box from the Opscode vagrant repo. Download the opscode-ubuntu-12.04 box from the following URL https://opscode-vmbento.s3.amazonaws.com/vagrant/opscode_ubuntu-12.04_provisionerless.box

Step 2 − Once you have the Vagrant file, download the path you need to edit the Vagrant file.

In the above program, you need to update the <YOUR_ORG> name with the correct or required organization name.

Step 3 − Next step after the configuration is, to get the vagrant box up. For this, you need to move to the location where Vagrant box is located and run the following command.

Step 4 − Once the machine is up, you can login to the machine using the following command.

In the above command, vagrantfile is written in a Ruby Domain Specific Language (DSL) for configuring the vagrant virtual machine.

In the vagrant file, we have the config object. Vagrant will use this config object to configure the VM.

Inside the config block, you will tell vagrant which VM image to use, in order to boot the node.

In the next step, you will tell Vagrant to download the omnibus plugin.

After selecting the VM box to boot, configure how to provision the box using Chef.

Inside this, you need to set up instruction on how to hook up the virtual node to the Chef server. You need to tell Vagrant where you need to store all the Chef stuff on the node.
