Installing the Chef development kit on your workstation

If you want to use Chef, you'll need to install the Chef development kit (DK) on your local workstation first. You'll have to develop your configurations locally and use Chef to distribute them to your Chef server.

Chef provides a fully packaged version, which does not have any external prerequisites. This fully packaged Chef is called the omnibus installer. We'll see how to use it in this section.

How to do it...

Let's see how to install the Chef DK on your local workstation using Chef's omnibus installer:

Download the Chef DK for your specific workstation platform from https://downloads.chef.io/chef-dk/ and run the installer.
Verify that Chef installed all the required components:
