Chef Server - central repository for cookbooks, roles, and nodes

Cookbooks and Recipes - configuration scripts

Resources and Providers - declarative components for state management

Knife CLI - command-line tool for infrastructure management

Basic Concepts Overview

Node - a managed server or machine

Cookbook - collection of configuration recipes

Recipe - instructions to configure a resource

Resource - declarative definition of system state

Role/Environment - define node attributes and policies

Project Structure

cookbooks/ - main directory for recipes

recipes/ - individual configuration files

templates/ - configuration templates

attributes/ - define configurable variables

roles/ and environments/ - define node policies

Building Workflow

Write recipes and organize into cookbooks

Test locally using Chef Workstation and Test Kitchen
