3. So what’s Razor?
Cloud provisioning tool
Operating Systems AND Hypervisors
Physical AND virtual
Event-driven instead of user-driven

4. Why not just use templates?
They get old fast
Pre-packages bits are harder to maintain
No easy upgrade to next distro version

6. Auto-Discovered Real-Time Inventory
Data

Primarily using facter
For every hardware node
Eliminating inefficient, error-prone manual
processes
Full insight into the latest, up-to-date status
of your hardware inventory

7. Dynamic Image Selection
Selects the correct operating system image
Based on auto-discovered, real-time
inventory data

8. Model-Based Provisioning
Models the desired state of each hardware
node and its operating system
Automatically tracks provisioning progress
toward this state
Full control over a node’s boot sequence and
a complete log of its lifecycle

9. Open APIs and Plug-in Architecture
RESTful open APIs
Full programmatic control of the rules and
models that govern operating system image
selection and hardware provisioning
Enables the Puppet community to collaborate
and share plug-ins to support any operating
system and any boot sequence

12. Razor installation using Puppet
node razor {
class { 'sudo':
config_file_replace => false,
}
include razor
}

13. Add a broker
rz_broker { 'puppet_broker':
ensure => present,
plugin => 'puppet',
metadata => {
broker_version => '2.7.18',
server => 'puppet.purevirtual.lab',
}
}
© Copyright 2012 EMC Corporation. All rights reserved. 13

14. Add an image to deploy
rz_image { "ubuntu_precise_image":
ensure => present,
type => 'os',
version => '12.04.1',
source =>
"http://ftp.sunet.se/pub/os/Linux/distributions/ubunt
u/ubuntu-cd/12.04.1/ubuntu-12.04.1-server-
amd64.iso",
}

15. Add a model for deployment
rz_model { 'install_ubuntu_precise':
ensure => present,
description => 'Ubuntu Precise',
image => 'ubuntu_precise_image',
metadata => {'domainname' => 'purevirtual.lab',
'hostname_prefix' => 'ubuntu-', 'root_password' =>
'password'},
template => 'ubuntu_precise',
}

16. Finally, create a policy to tie it all
together
rz_policy { 'ubuntu_precise_policy':
ensure => present,
broker => 'puppet_broker',
model => 'install_ubuntu_precise',
enabled => 'true',
tags => ['memsize_1GiB'],
template => 'linux_deploy',
maximum => 10,
}
