Puppetize everything!


What is Puppet? IT automation software Helps system administrators manage

infrastructure throughout its lifecycle Provisioning and configuration Patch management and compliance Highly scalable


How scalable? Google manages more than 50000 systems Zynga scaled from 0 to 10000 servers in 2

months I am managing tens of machines!


Why is Puppet cool? Centralized, Scalable configuration management for

server farms Abstracted from underlying OS (to a point) Configurations can be stored in a version control

system (like Git) for historical change tracking Automated configuration of individual machines

based on hardware/software configuration Auditing of configuration of individual machines


Where Puppet helps Bridge the gap between sysadmins and app/dev

teams Using a common structure to create Dev, QA and

Production environments Standardizing applications and their configurations Result: Consistent platforms throughout with minimal

pain


Puppet gives youSoftware-Defined Infrastructure


Example of a Puppet manifestnode /blogserver/ { include ntp include wordpress firewall { '100 allow http': proto => 'tcp', dport => '80', action => 'accept', }}


Puppet Architecture


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


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


So how does it work?


Auto-Discovered Real-Time Inventory Data Boots a Micro-Kernel 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


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

inventory data No manual intervention needed


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


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


Metal-to-Cloud Application Lifecycle Management No need for siloed management tools!


Puppet + Razor = Good!


Razor installation using Puppetnode razor { class { 'sudo': config_file_replace => false, } include razor}


Add a brokerrz_broker { 'puppet_broker': ensure => present, plugin => 'puppet', metadata => { broker_version => '2.7.18', server => 'puppet.purevirtual.lab', } }


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


Add a model for deploymentrz_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',}


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


DEMOTIME!
