Webinar Objectives and Style
3
Multi-week Webinar Series
• After completing of this webinar series you will be
able to
• Automate common infrastructure tasks with Chef
• Describe Chef’s architecture
• Describe Chef’s various tools
• Apply Chef’s primitives to solve your problems
How to learn Chef
• You bring the domain expertise about your business
and infrastructure
• Chef provides a framework for automating your
infrastructure
• Our job is to work together to teach you how to
model and automate your infrastructure with Chef
Chef is a Language
• Learning Chef is like learning the basics of a
language
• 80% fluency will be reached very quickly
• The remaining 20% just takes practice
• The best way to learn Chef is to use Chef

Chef Solves This Problem
• But you already
guessed that, didn’t
you?
26
Chef is Infrastructure as Code
• Programmatically
provision and
configure components

27
Chef is Infrastructure as Code
• Treat like any other
code base

28
Chef is Infrastructure as Code
• Reconstruct business
from code repository,
data backup, and
compute resources

30
Configuration Code
• Chef ensures each Node complies with the policy
• Policy is determined by the configurations in each
Node’s run list
• Reduce management complexity through abstraction
• Store the configuration of your infrastructure in
version control
31
Declarative Interface to Resources
• You define the policy in your Chef configuration
• Your policy states what state each resource should
be in, but not how to get there
• Chef-client will pull the policy from the Chef Server
and enforce the policy on the Node
32
Managing Complexity
• Resources
• Recipes
• Nodes
• Search
33
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
34
Resources in Recipes
• Resources are the fundamental building blocks of
Chef configuration
• Resources are gathered into Recipes
• Recipes ensure the system is in the desired state
35
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
36
Example Recipe
package "httpd" do
action :start
end
template "/etc/httpd/conf/httpd.conf" do
source "httpd.conf.erb"
owner "root"
group "root"
mode "0644"
variables(:allow_override => "All")
notifies :reload, "service[httpd]"
end
service "httpd" do
action [:enable,:start]
supports :reload => true
end
37
Nodes
38
Nodes Adhere to Policy
• 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
39
Run List
Node

Chef chef-client

Run List

Chef chef-client
What policy should I follow?
"recipe[ntp::client]"

41
Run List
Enterprise
Chef chef-client
What policy should I follow?
"recipe[ntp::client]"
"recipe[users]"
"role[webserver]"
42
Run List Specifies Policy
• 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
43
Search
• Search for nodes with Roles
• Find Topology Data
• IP addresses
• Hostnames
• FQDNs

65
Manage Complexity
• Determine the desired state of your infrastructure
• Identify the Resources required to meet that state
• Gather the Resources into Recipes
• Compose a Run List from Recipes
• Apply a Run List to each Node in your environment
• Your infrastructure adheres to the policy modeled in
Chef
66
Configuration Drift
• Configuration Drift happens when:
• Your infrastructure requirements change
• The configuration of a server falls out of policy
• Chef makes it easy to manage
• Model the new requirements in your Chef
configuration files
• Run the chef-client to enforce your policies
67
Recap
• In this section, we have
• Described how Chef thinks about Infrastructure
Automation
• Defined the following terms:
• Resource
• Recipe
• Node
• Run List
• Search

  • 32. Declarative Interface to Resources • You define the policy in your Chef configuration • Your policy states what state each resource should be in, but not how to get there • Chef-client will pull the policy from the Chef Server and enforce the policy on the Node 32
  • 33. Managing Complexity • Resources • Recipes • Nodes • Search 33
  • 34. 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 34
  • 35. Resources in Recipes • Resources are the fundamental building blocks of Chef configuration • Resources are gathered into Recipes • Recipes ensure the system is in the desired state 35
  • 36. 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 36
  • 37. Example Recipe package "httpd" do action :start end template "/etc/httpd/conf/httpd.conf" do source "httpd.conf.erb" owner "root" group "root" mode "0644" variables(:allow_override => "All") notifies :reload, "service[httpd]" end service "httpd" do action [:enable,:start] supports :reload => true end 37
  • 39. Nodes Adhere to Policy • 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 39
  • 41. Run List Node Enterprise Chef chef-client What policy should I follow? "recipe[ntp::client]" "recipe[users]" "role[webserver]" 41
  • 42. Run List Enterprise Chef chef-client What policy should I follow? "recipe[ntp::client]" "recipe[users]" "role[webserver]" 42
  • 43. Run List Specifies Policy • 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 43
  • 44. Search • Search for nodes with Roles • Find Topology Data • IP addresses • Hostnames • FQDNs http://www.flickr.com/photos/kathycsus/268677262544
