Organizations
Relax—a cheat sheet is not really cheating. It's a checklist to make sure you stay focused before, during, and after the interview. Creating a cheat sheet will help you feel more prepared and confident. You shouldn't memorize what's on the sheet or check it off during the interview. You should use your cheat sheet to remind you of key facts. The Cheat Sheet is still in construction phase and there are some ingredients that need to be added but most of them are there. I hope this helps with the last levels cuz it's helped me alot!! Once you memorize what item is from what category the game shouldn't be a struggle. All cheat sheets, round-ups, quick reference cards, quick reference guides and quick reference sheets in one page.

- Completely independent tenants of Enterprise Chef
- Provide multi-tenancy in Enterprise Chef
- Share nothing with other organizations
- May represent different
- Companies
- Business Units
- Departments
- Each Organization may have multiple Users
- Manage an Organization’s Users via the Enterprise Server interface
Environments
Environments reflect your patterns and workflow, and can be used to model the life-stages of your application
- Development
- Test
- Staging
- Production
- etc.
Every Organization starts with a single environment!
Environments may include data attributes necessary for configuring your infrastructure, e.g.
- The URL of your payment service’s API
- The location of your package repository
- The version of the Chef configuration files that should be used
Roles
Roles may include an ordered list of Chef configuration files that should be applied
- This list is called a Run List
- Order is always important in the Run List
Roles may include data attributes necessary for configuring your infrastructure, for example:
- The port that the application server listens on
- A list of applications that should be deployed
Node
Nodes represent the servers in your infrastructure
- Could be physical servers or virtual servers
- May represent hardware that you own or compute instances in a public or private cloud
- Could also be network hardware – switches, routers, etc
Each Node will
- Belong to one Organization
- Belong to one Environment
- Have zero or more Roles
The chef-client application runs on each node, which
- Gathers the current system configuration of the node
- Downloads the desired system configuration policies from the Chef server for that node
- Configures the node such that it adheres to those policies
Resources
A Resource represents a piece of the system and its desired state
- A package that should be installed
- A service that should be running
- A file that should be generated
- A cron job that should be configured
- A user that should be managed
- and more
Resources are the fundamental building blocks of Chef configuration
Resources are gathered into Recipes
Chef Cheat Sheet
Recipes ensure the system is in the desired state
Recipes
- Configuration files that describe resources and their desired state
- Recipes can:
- Install and configure software components
- Manage files
- Deploy applications
- Execute other recipes
- and more
Cookbooks
- Recipes are stored in Cookbooks
- Cookbooks contain recipes, templates, files, custom resources, etc
- Code re-use and modularity
- A cookbook is like a “package” for Chef recipes.
- It contains all the recipes, files, templates, libraries, etc. required to configure a portion of your infrastructure
- Typically they map 1:1 to a piece of software or functionality.
Run List
- The Run List is an ordered collection of policies that the Node should follow
- Chef-client obtains the Run List from the Chef Server
- Chef-client ensures the Node complies with the policy in the Run List
Knife
Knife provides an API interface between a local Chef repository and the Chef Server, and lets you manage:
- Nodes
- Cookbooks and recipes
- Roles
- Stores of JSON data (data bags), including encrypted data
- Environments
- Cloud resources, including provisioning
- The installation of Chef on management workstations
- Searching of indexed data on the Chef Server
Node Objects
- When you are writing Recipes, the Node object is always available to you.
- Every node must have a unique name within an organization
- Chef defaults to the Fully Qualified Domain Name of the server, i.e. in the format server.domain.com
- Nodes are made up of Attributes •
- Many are discovered automatically (platform, ip address, number of CPUs)
- Many other objects in Chef can also add Node attributes (Cookbooks, Roles and Environments, Recipes, Attribute Files)
- Nodes are stored and indexed on the Chef Server
What are Attributes?
- Attributes represent information about your node
- The information can be autodetected from the node (e.g.# of CPUs, amount of RAM) & populated by Ohai
- You can also set attributes on your node using cookbook recipes & attribute files, roles, environments, etc
- Attributes keep the program code separate from data.
- All attributes are set on the “node object”, and are indexed for search on the server
Attribute Sources Attributes can be set at various levels (in increasing order of precedence)
- Automagically on the node itself (by Ohai)
- In roles
- In environments
- In cookbook recipes
- In cookbook attribute files
Attributes can be set in the cookbook’s attributes file ./cookbooks/<cookbook>/attributes/default.rb. The Format is In Recipes:
Data Bags
A data bag is a container for items that represent information about your infrastructure that is not tied to a single node
Examples
- Users
- Groups
- Application Release Information
