Cobbler external inventory script
=================================
Ansible has a feature where instead of reading from /etc/ansible/hosts
as a text file, it can query external programs to obtain the list
of hosts, groups the hosts are in, and even variables to assign to each host.
To use this, copy this file over /etc/ansible/hosts and chmod +x the file.
This, more or less, allows you to keep one central database containing
info about all of your managed instances.
This script is an example of sourcing that data from Cobbler
(http://cobbler.github.com). With cobbler each --mgmt-class in cobbler
will correspond to a group in Ansible, and --ks-meta variables will be
passed down for use in templates or even in argument lines.
NOTE: The cobbler system names will not be used. Make sure a
cobbler --dns-name is set for each cobbler system. If a system
appears with two DNS names we do not add it twice because we don't want
ansible talking to it twice. The first one found will be used. If no
--dns-name is set the system will NOT be visible to ansible. We do
not add cobbler system names because there is no requirement in cobbler
that those correspond to addresses.
See http://ansible.github.com/api.html for more info
Tested with Cobbler 2.0.11.

# When generating inventory, Ansible needs to know how to address a server.
# Each EC2 instance has a lot of variables associated with it. Here is the list:
# http://docs.pythonboto.org/en/latest/ref/ec2.html#module-boto.ec2.instance
# Below are 2 variables that are used as the address of a server:
# - destination_variable
# - vpc_destination_variable
# This is the normal destination variable to use. If you are running Ansible
# from outside EC2, then 'public_dns_name' makes the most sense. If you are
# running Ansible from within EC2, then perhaps you want to use the internal
# address, and should set this to 'private_dns_name'.
destination_variable = public_dns_name
# For server inside a VPC, using DNS names may not make sense. When an instance
# has 'subnet_id' set, this variable is used. If the subnet is public, setting
# this to 'ip_address' will return the public IP address. For instances in a
# private subnet, this should be set to 'private_ip_address', and Ansible must
# be run from with EC2.
vpc_destination_variable = ip_address
# API calls to EC2 are slow. For this reason, we cache the results of an API
# call. Set this to the path you want cache files to be written to. Two files
# will be written to this directory:
# - ansible-ec2.cache
# - ansible-ec2.index
cache_path = /tmp
# The number of seconds a cache file is considered valid. After this many
# seconds, a new API call will be made, and the cache file will be updated.
