• A named match rule
• Rules can have complex logic
[“or”,
[“in”, [“fact”, “macaddress”],
“de:ad:be:ef:00:01”,
“de:ad:be:ef:00:02”],
[“=”, “2”, [“fact”, “processorcount”]]]

17. Installer example
--# redhat.yaml
os_version: 6
description: Red Hat EL installer
boot_sequence:
1: boot_install
default: boot_local

18. Broker example
# broker.json
{
“name”: "puppet",
“broker-type”: "puppet",
“configuration”: {
“server”: "puppet.local.watzmann.net",
“certname”: …,
“environment”: “production”
}
}

19. Template example
#!ipxe
# boot_install.erb
kernel <%= repo_url(“/vmlinuz”) %>
ks=<%= file_url(“kickstart”) %>
# os_boot.erb
hostname <%= node.hostname %>
yum -y install rubygems facter
[ $? -eq 0 ] && curl <%= log_url(“ok”) %>
|| curl <%= log_url(“fail”, :error) %>

20. Policy example
# policy.json
{
“name”: “centos”,
“repo”: { “name”: “centos-6.4” },
“installer”: { “name”: “centos” },
“broker”: { “name”: “puppet” },
“hostname”: “host${id}.example.com”,
“root_password”: “secret”,
“max_count”: 20,
“enabled”: true,
“rule_number”: 100,
“tags”: [{ “name”: “large-server”,
“rule”: [ … ] }]

“broker”: { “name”: “puppet” },
“hostname”: “controller${id}.example.com”,
“root_password”: “secret”,
“max_count”: 1,
“enabled”: true,
“rule_number”: 100,
“tags”: [{ “name”: “controller”,
“rule”: [ … ] }]
}

26. Openstack: Compute Policy
# compute.json
{
“name”: “compute”,
“repo”: { “name”: “fedora-19” },
“installer”: { “name”: “fedora” },
“broker”: { “name”: “puppet” },
“hostname”: “compute${id}.example.com”,
“root_password”: “secret”,
“max_count”: 1,
“enabled”: true,
“rule_number”: 90,
“tags”: [{ “name”: “compute”,
“rule”: [ … ] }]
}

27. Openstack: site.pp
node /controller/ {
class { 'openstack::controller':
public_address => '192.168.100.10',
public_interface => 'eth0',
private_interface => 'eth1',
…
}
