Puppet & VMware

• Multiple integration ways…

• Razor

• vCenter integration

• vFabric Application Director integration

• 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 • operating 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 information on hardware, type of server and type of virtualization it is on

• Real time

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 attributes 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 automatic: • 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

• After completing the provisioning of OS/Hypervisor, a Broker comes into play for managing configuration

• 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 configuration

• 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

• Automatically install Puppet Agent

VCSA & vShield Modules

• Open source Puppet modules • Developed by VMware and PuppetLabs • Management for the vCenter Server Appliance (VCSA)

• Initialization • Datacenter and Cluster configuration • ESXi Host

• Management for the vShield Manager • Initialization • Association to vCenter • vShield Edge Deployment • vShield Edge Configuration

vFabric Application Director

• vFabric Application Director is a cloud-enabled application provisioning and maintenance solution

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

• Create complete deployment blueprint

AppDirector integration

• The Puppet integration solution enables • deploy applications via Puppet manifests

• deploy vFabric Application Director blueprints using existing Puppet modules

• Leverages vFabric Application Director management console to • configure Puppet classes

• Use Puppet modules as vFabric Application Director blueprints
