The different search indexes for node data in Chef Server are as follows:- Data bags: Data bags are like a container where global data is stored and shared across the Chef nodes and these data are accessible by Chef Server. Data bags are used to securely store information like admin credentials etc in the form of JSON files. These are indexed and are loaded in a Chef search. Environment: We at times want our nodes to converge to a testing environment or maybe to a production environment so that admins can know in which stage of the code development, the node is included. Environment details are also updated in Chef Server and could be searched for. “_default” is the default environment for any Chef node. Multiple environments could be added and worked upon.’ Node: Node is a system that we want to be configured and maintained using Chef Infra Client. The node could be a physical server or a virtual machine or a cloud machine. Details of the node are also updated in Chef Server and searched upon. Role: Role is used for defining certain patterns or processes across all Chef nodes. Multiple configurations of the nodes at a different time could be achieved in Chef using the “roles” feature.
