§  Start your engine:

Click Fail

Add VPC Hosts to VCSA §  Continuing from the vCenter view of the vSphere Web Client §  In the main content pane, click Related Objects > Clusters §  Click on VPC on the list §  Click the second plus icon to add a host

• Host name: Enter first host FQDN •  Location: Confirm the location is set.

• Click NEXT

§ … §  Repeat Manually?

Problem

Challenges: §  Reduce deployment time §  Reduce complexity §  Scale … Fast Solution: 1.  Automate 2.  See first rule

Automation Challenges

§  Service APIs: •  vCenter: vSphere API (soap) •  vCNS: vShield API (REST)

•  vCD: vCD API (REST)

§  vCenter/vCNS servers are appliances

12 Confidential

Why not ‘puppet device’?

§  Limited to one device at a time:

Puppet Management Server

VMware vCenter

VMware vShield

Datacenter

ESXESXESX

vSphere API

vShield API

Solution: Take the road less traveled

§  Everything is a Native Resource §  Transport to the rescue

•  vCenter/vCNS Appliance: SSH •  vCenter API: RbVmomi

•  vShield API: rest-client + subset of savon project •  vCD API: rest-client

14 Confidential

Transport Resource

§  Credentials §  Connectivity Options § Multiple connections

Lessons Learned

§ Working with APIs §  Puppet 2.7.x -> Puppet 3.x §  Puppet Wat?

23 Confidential

Working with APIs

§  Functionalities not always in API* §  Dealing with API versions § Metaprogramming * Even if you are @wlam :)

24 Confidential

Dealing with outliers

§  Accept work around ssh.exec( " esxcfg-vmknic -i #{opts[:new_mgmt_ip]} -n #{opts[:new_mgmt_mask]} -p 'Management Network' && esxcfg-route -a default #{opts[:new_mgmt_gw]} && esxcfg-vswitch -p 'Management Network' -v #{opts[:new_mgmt_vlan]} vSwitch0 " )

§  Last resort, file a ticket t = ServiceNow::Request.new( :subject => ”Please click yes" ) ServiceNow.create(t)

25 Confidential

Testing API versions

§  puppet apply --libdir=/dev/null §  bundler exec + Gemfile source 'file:///opt/repo/’ source 'https://rubygems.org’ gem 'facter’ gem 'puppet', '3.2.2’ gem 'gyoku', '1.0.0z2’ gem 'hashdiff’ gem 'net-ssh’ gem 'nokogiri’ gem 'nori', '1.1.4’ gem 'rbvmomi', '1.6.0.z1’ gem 'rest-client’ gem 'pry'

26 Confidential

Metaprogramming

Good §  Reduces boiler plate code §  No more API ‘transfer’ bugs §  API reference = Resource reference Bad §  Difficult to debug §  Fixing API issues results in surprises §  Not all APIs are designed to be idempotent

•  action => { :create, :modify }

27 Confidential

Puppet 3 Upgrade

§ What the scope? § Where’s my HOME? §  Ruby 1.9.3

28 Confidential

What the scope?

§  Fully qualify ::class::var §  Fix your template @var, scope.lookup(‘::class::var’)

29 Confidential

Where’s my HOME?

§  Exec specify HOME. §  Providers Fix:

if respond_to? :has_command has_command(:brew, "/usr/local/bin/brew") do environment({ 'HOME' => ENV['HOME'] }) end else commands :brew => "/usr/local/bin/brew” end

30 Confidential

Puppet Wat

Boolean: §  adrientthebo/boolean §  vmware_lib property §  Symbool in Hash

What the undef? §  Careful about behavior

ENC Data §  ENC integer .to_s

31 Confidential

Where we are Today

§  Deploy VPC: # §  95% reduction in deployment time §  Configuration Management = Version

§ Metrics: •  47 Modules •  70 Custom Resources

•  1400 Resources

32 Confidential

Work at VMware

Challenges: §  Software Defined Datacenter

• Data driven configuration management

§  Software Defined Networking •  vCNS, Nicira VSX

§  Scale + Speed •  10X, 100X, 1000X ? •  Faster !!! Now !!!
