Resources

15. github.com/mattray/openstack-cookbooks
• Chef repository
• cookbooks
• roles
• data bags
• stable branches
• issues

16. Chef Nodes
• Each system you manage is called a node.
• The chef-client runs on nodes.
• The ohai discovery agent runs on nodes.
• Nodes have a run list.
• Searchable

17. Chef Resources
package "haproxy" do
action :install
end
• Have a type.
•
template "/etc/haproxy/haproxy.cfg" do
Have a name. source "haproxy.cfg.erb"
• Have parameters.
owner "root"
group "root"
• Take action to put the resource mode 0644
notifies :restart, "service[haproxy]"
in the declared state. end
• Can send notifications to other service "haproxy" do
resources. supports :restart => true
action [:enable, :start]
• Take action through Providers end

18. Chef Recipes
extra_packages = case node[:platform]
when "ubuntu","debian"
%w{
ruby1.8
ruby1.8-dev
• Ordered list of Resources rdoc1.8
ri1.8
• Idempotent execution }
libopenssl-ruby
• Ruby
end
extra_packages.each do |pkg|
package pkg do
action :install
end
end

19. Chef Cookbooks
• Cookbooks are packages for Recipes
• Recipes
• Assets (files/templates)
• Attributes
• Metadata
• Distributable and managed as Source
• community.opscode.com

• glance
• nova
• swift
• Installed

• apt
• mysql
• openssl
• rabbitmq

21. Chef Roles
• Roles describe the node.
• Roles have run lists.
• Roles have attributes.
• Roles may contain other roles.

• nova-single-machine
• nova-db
• nova-rabbitmq-server
• glance-single-machine
• nova-multi-controller
• nova-multi-compute

23. Chef Data Bags
• Data bags store arbitrary data
• JSON
• Searchable

24. OpenStack Data Bags
knife data bag create openstack
knife data bag from file openstack defaults.json
knife data bag from file openstack glance.json
knife data bag from file openstack images.json
knife data bag show openstack images
id: images
images:
http://uec-images.ubuntu.com/lucid/current/ubuntu-10.04-

arch: x86_64
distro: Ubuntu
image: lucid-server-uec-amd64.img
kernel: lucid-server-uec-amd64-vmlinuz-virtual
version: 10.04

26. Deploying OpenStack

documented

27. Spiceweasel
• yaml/json for describing infrastructure
• generates knife commands
• shareable "best practices"
• infrastructure.yml included
• bit.ly/spcwsl

28. Testing OpenStack
• bare-metal to OpenStack
• ~15 minutes
• pxe_dust cookbook
• 2 networks
• admin
• public
