The document provides an overview of Puppet, an open source configuration management tool. It summarizes Puppet's key components including the Puppet language for defining infrastructure, Facter for collecting node facts, Hiera for separating configuration from code, and PuppetDB for storing configurations and reports. It also describes Puppet Enterprise which adds features like interactive event analysis, centralized inventory, and live management capabilities. The document encourages participation in the Puppet community through training, contributing code/modules, and mentions job opportunities at Puppet Labs.
16. Language: Easy to Get Started
class ssh {
!
package { 'openssh-server':
ensure => present,
}
!
file { 'sshd_config':
path => '/etc/ssh/sshd_config',
source => ‘puppet:///modules/ssh/sshd_config',
require => Package['openssh-server'],
notify => Service['sshd'],
}
!
service { 'sshd':
ensure => running,
enable => true,
require => File['sshd_config'],
}
!
}
17. New Approach: Software
Defined Infrastructure
1. DEFINE 2. SIMULATE
4. REPORT

3. ENFORCE
}
18. Facts
The node sends
normalized data
about itself to the
Puppet Master.
1
Catalog
Puppet uses the Facts to
compile a Catalog that
specifies how the node
should be configured.
2
Report
Puppetʼs open API
can also send data
to third party tools.
4
Report
The node
reports back
to Puppet
indicating the
configuration is
complete, which
is visible in the
Puppet Dashboard.

• Validated version in Puppet
Enterprise
34. MCollective
• Powerful command and control tool
• Parallel,real-time execution across
your whole network
• Real-time discovery of all nodes and
their functions

Live Management in Puppet
Enterprise
35. PuppetDB
• Stores all configurations,facts and
reports
• Knows everything there is to know
about your infrastructure
• Foundation for nearly all reporting
and analysis in Puppet Open Source
and Puppet Enterprise
36. Facter
• Facts: bits of data that you care about
• Core inputs for customizing Puppet
configurations per host
• Easily pluggable to collect new data
or store it in existing databases
• Now structured and trusted facts
• Foundation for Puppet Enterprise
Node Inventory
37. Hiera
• Separate site configuration data from
reusable code
!
• Iterate and promote code quickly
without having to manage dev/test
configuration differences
38. Razor
• Rules-based provisioning for bare
metal hardware and virtual servers
• Feeds directly into your Puppet
infrastructure

42. People Love our
Worldwide Training!
I liked being with other sharp admins in an environment where
"cross-pollination" and experimentation were encouraged.

“A brilliant course to jump into using puppet fast and effectively.
“
Very useful information, a good start for our Puppet team, and
would highly recommend it.
