Chef for Absolute Beginners

Explore the three flavors of chef—open source, hosted, and private—and compare features, deployment options, node limits, and costs, including prerequisites and support arrangements.

Understand the chef ecosystem's three core components—workstation, server, and nodes—and their roles in information technology infrastructure: workstation enables interaction, server stores policies, and nodes run chef clients.

Explore the chef ecosystem by examining the chef server, workstation, and nodes, and discover how tools like knife, chef repository, and Ohai drive cookbooks, run lists, environments, and data bags.

Explore how traditional IT terminologies map to Chef, including organizations, multi-tenancy, environments from development to production, and nodes with multiple roles.

Understand our lab setup with a chef workstation on a local Windows laptop, a chef server in the cloud, and two virtual machines managed by chef.

Download the chef client for Windows, choose the 64-bit version, and install it on your workstation. Accept the license and verify the installation in the AAPS code folder.

Sign up for a hosted chef account, create an organization, download the starter kit, and explore nodes, reports, and cookbooks in the chef server cloud.

Extract the starter kit, inspect the chef repo and knife.rb, use the pem file to connect to the hosted chef server, and verify with knife client and node lists.

Assign static IPs to nodes, verify ssh is running with putty, enable ssh on any node, and configure sudo access for the chef user before bootstrapping.

Learn how to bootstrap a node to a chef server using the knife tool, automating node creation, client setup, ssh communication, and chef client installation, eliminating manual node setup.

Bootstrap a node with chef by creating the node and client on the chef server, then connect via ssh to install the chef client, and verify with knife node list.

Explore how cookbooks organize all configurations and policies to bring a node to the desired state in Chef, including recipes, resources, attributes, templates, and run lists.

Create an Apache cookbook to install the Apache package, start and enable the Apache service, then upload the cookbook to the chef server and run it on the target node.

Learn how the chef run process authenticates the chef client, fetches cookbooks, loads libraries, and applies run list recipes to bring a node to the desired state.

Explore the most commonly used Chef resources for managing IT infrastructure, including the package, service, directory, file, bash, execute, cron, and cookbook_file resources.

Explore how the chef package resource manages linux packages, performing install, upgrade, remove, purge, or reconfigure actions, with attributes such as arch, allow_downgrade, flush_cache, options, source, and version.

Manage Linux services with the Chef service resource to enable, disable, start, stop, restart, or reload a service, and configure commands and supports for action control.

Learn how to use the directory resource to manage linux directories, including creating and deleting directories, and configuring path, owner, group, mode (octal values), and recursive options for precise control.

Chef's file resource manages Linux files by actions like create, delete, and touch, and controls attributes such as path, content, owner, group, mode, and backup.

Chef's bash resource runs bash scripts on Linux with the bash interpreter, exposing attributes such as code, command, creates, working directory, user, group, environment, timeout, path, return, and flags.

Learn how the Chef execute resource runs commands on Linux, default and nothing actions, and how attributes such as command, creates, user, group, environment, timeout, path, and return indicate success.

Manage cron jobs on the Linux system using the cron resource to create, update, or delete jobs; configure command, day, hour, minute, month, week, user, path, shell, home, and mail.

Transfer files from workstation to chef-managed nodes using the cookbook underscore file resource, ensuring consistent configuration across nodes; configure actions and attributes like path, content, owner, group, mode, and backup.

Bootstrap a second Ubuntu node, implement a cross-platform Apache recipe in the cookbook, and apply it with a bootstrap command and Chef client to reach the desired state.
