Final answer:
A Chef installation requires workstations, managed servers (nodes), and a Chef-repository in addition to a master server.
Step-by-step explanation:
In addition to a master server, a Chef installation requires several other components to function properly. These include workstations where users write cookbooks and other configurations, nodes that are the managed servers, and a Chef-repository for storing your cookbooks and other infrastructure code. It is essential for a Chef setup to have these elements in place in order to automate and manage the infrastructure successfully.
The chef workstation is where the Chef development process takes place, including writing and testing cookbooks. Chef nodes are the servers or virtual machines that are managed by the Chef server and execute the desired configurations specified by the Chef recipes.
