Razor, Puppet & VMware

Giuseppe Guglielmetti vExpert VMware VSP, VTSP, VCP4/5, vExpert 2011/2012 Kiratech srl


Who I am •  Senior System Engineer for Kiratech •  Virtualiza7on, Storage and Backup specialist •  VCP 4,5, vExpert 2011/2012 •  Veeam Technical Sales Professional •  Cisco Unified Compu7ng Technology Support

Specialist @gguglie


Puppet & VMware •  Mul7ple integra7on ways… •  Razor •  vCenter integra7on •  vFabric Applica7on Director integra7on •  Official VCSA & vShield modules (NEW!)

•  ..plus the obvious one: just manage a VM as a physical node (and Facter is your friend!)


Razor •  Tool developed by Nick Weaver •  Open source •  Dynamic provisioning of •  opera7ng systems •  hypervisors

•  for both •  physical server •  virtual servers

•  Event driven


How Razor works (1) Discovery •  Single purpose: find out what a

compute node is made of •  MicroKernel booted through

PXE •  The MicroKernel uses Puppet’s

Facter to gather informa7on on hardware, type of server and type of virtualiza7on it is on

•  Real 7me


How Razor works (2) Tagging •  Allows to group nodes by

applying tags •  A Tag Rule apply a Tag to a node •  A Tag Rule contains qualifying

rules called Matchers •  Matchers use aaributes

collected during discovery to classify nodes


How Razor works (3) Models •  Model template: one or more files that describe

how to do something •  Model Templates for installing common things

are available out of the box •  Model: instance of a Model Template plus some

metadata required (like license key, password, hostname, domain…)


How Razor works (4) Policy •  Is a rule that applies a Model to

a Node based on matching against Tags

•  Fully automa7c: •  a Node checks-‐in •  Razor checks the Policies looking

for a match •  when a match is found it applies

the Policy and binds the Model


How Razor works (5) Broker plugin (1) •  A Broker is an external system that will configure

a Node for its true purpose •  Ader comple7ng the provisioning of OS/

Hypervisor, a Broker comes into play for managing configura7on

•  The standard broker is Puppet Master •  The Puppet Broker Plugin enables both agent

handoff (Linux) and proxy handoff (vSphere ESXi)


How Razor works (6) Broker plugin (2) •  Razor delivers all the

metadata including tags to Puppet

•  Puppet can use tags passed by Razor to make decisions on configura7on •  e.g.: link similarly tagged ESXi

nodes into the same cluster


vCenter integration

•  Puppet subcommand node_vmware •  Puppet Enterprise only •  List VM •  Create VM from template •  Start/stop VM •  Destroy VM •  Automa7cally install Puppet Agent

VCSA & vShield Modules •  Open source Puppet modules •  Developed by VMware and PuppetLabs •  Management for the vCenter Server Appliance (VCSA) •  Ini7aliza7on •  Datacenter and Cluster configura7on •  ESXi Host

•  Management for the vShield Manager •  Ini7aliza7on •  Associa7on to vCenter •  vShield Edge Deployment •  vShield Edge Configura7on


vFabric Application Director

•  vFabric Applica7on Director is a cloud-‐enabled applica7on provisioning and maintenance solu7on

•  simplifies how to create and standardize applica7on deployment topologies across cloud services

•  Create complete deployment blueprint


AppDirector integration

•  The Puppet integra7on solu7on enables •  deploy applica7ons via Puppet manifests •  deploy vFabric Applica7on Director blueprints

using exis7ng Puppet modules •  Leverages vFabric Applica7on Director

management console to •  configure Puppet classes •  Use Puppet modules as vFabric Applica7on

Director blueprints
