Compare imperative scripting and declarative automation in configuration management for heterogeneous environments, using Chef, Ansible, and Puppet. Understand push and pull models, and how idempotency and convergence ensure consistent state.
Explore Chef, a Ruby-based declarative automation tool that configures, manages, and deploys infrastructure as code across environments using server-client and Chef Zero models, with idempotent execution.
Configure chef clients by ensuring network connectivity among server, workstation, and client, verify hostnames, and install via package managers or knife bootstrap with prerequisites like ntp, space, and supported os.
Navigate the Chef resources documentation, understand resource components and actions, and review built-in resources like user and file to confidently write Chef code.
Build your first chef cookbook to install, configure, and start the Apache web server, using chef generate, default.rb recipes, and local-mode runs to verify with chef zero.
Explore how Chef RunLists order recipes across nodes using cookbooks and the chef-client, with syntax like recipe [cookbook::recipe], perform dry runs, and manage multiple recipes in a single runlist.
Demonstrate four runlist scenarios in Chef, from single to multiple recipes, using an Apache web server example to install, configure, and verify with dry runs and chef-client execution.
Learn how to use include_recipe to compose recipes from multiple files, organizing large Chef code in default.rb and RunList, with a practical demo.
Learn how to manage cookbook dependencies by linking recipes from other cookbooks, such as linking the ntp server to the web server cookbook, with a quick demo.
Configure and test the communication between the Chef workstation and the hosted Chef server using knife to fetch certificates, verify connectivity, and upload the starter cookbook.
Demonstrates production use of Chef automation with a hosted server: validate certificates, upload cookbooks, create run lists, and run chef-client from both client and workstation using Knife.

What is Chef?
Chef Software is a Configuration management and automation tool used to make your applications and systems easier to deploy. Avoid writing scripts or custom code to deploy and update your applications— automate in a language that approaches plain English.
