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

11 Confidential
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

VMware vCenter
VMware vShield
Datacenter

13 Confidential
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

Transport
§  Persistent shared connection
§  Connection cleanup after catalog apply
§  Open to supporting additional transport
•  VMware-RabbitMQ (REST)

22 Confidential
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 @lamw :)

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 !!!
