# Ansible EC2 external inventory script settings
#
[ec2]
# to talk to a private eucalyptus instance uncomment these lines
# and edit edit eucalyptus_host to be the host name of your cloud controller
#eucalyptus = True
#eucalyptus_host = clc.cloud.domain.org
# AWS regions to make calls to. Set this to 'all' to make request to all regions
# in AWS and merge the results together. Alternatively, set this to a comma
# separated list of regions. E.g. 'us-east-1,us-west-1,us-west-2'

# 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
# To tag instances on EC2 with the resource records that point to them from
# Route53, uncomment and set 'route53' to True.
route53 = False
# Additionally, you can specify the list of zones to exclude looking up in
# 'route53_excluded_zones' as a comma-seperated list.
# route53_excluded_zones = samplezone1.com, samplezone2.com
# 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.
cache_max_age = 300

'''
EC2 external inventory script
=================================
Generates inventory that Ansible can understand by making API request to
AWS EC2 using the Boto library.
NOTE: This script assumes Ansible is being executed where the environment
variables needed for Boto have already been set:
export AWS_ACCESS_KEY_ID='AK123'
export AWS_SECRET_ACCESS_KEY='abc123'
If you're using eucalyptus you need to set the above variables and
you need to define:
export EC2_URL=http://hostname_of_your_cc:port/services/Eucalyptus
For more details, see: http://docs.pythonboto.org/en/latest/boto_config_tut.html
When run against a specific host, this script returns the following variables:
- ec2_ami_launch_index
- ec2_architecture
- ec2_association
- ec2_attachTime
- ec2_attachment
- ec2_attachmentId
- ec2_client_token
- ec2_deleteOnTermination
- ec2_description
- ec2_deviceIndex
- ec2_dns_name
- ec2_eventsSet
- ec2_group_name
- ec2_hypervisor
- ec2_id
- ec2_image_id
- ec2_instanceState
- ec2_instance_type
- ec2_ipOwnerId
- ec2_ip_address
- ec2_item
- ec2_kernel
- ec2_key_name
- ec2_launch_time
- ec2_monitored
- ec2_monitoring
- ec2_networkInterfaceId
- ec2_ownerId
- ec2_persistent
- ec2_placement
- ec2_platform
- ec2_previous_state
- ec2_private_dns_name
- ec2_private_ip_address
- ec2_publicIp
- ec2_public_dns_name
- ec2_ramdisk
- ec2_reason
- ec2_region
- ec2_requester_id
- ec2_root_device_name
- ec2_root_device_type
- ec2_security_group_ids
- ec2_security_group_names
- ec2_shutdown_state
- ec2_sourceDestCheck
- ec2_spot_instance_request_id
- ec2_state
- ec2_state_code
- ec2_state_reason
- ec2_status
- ec2_subnet_id
- ec2_tenancy
- ec2_virtualization_type
- ec2_vpc_id
These variables are pulled out of a boto.ec2.instance object. There is a lack of
consistency with variable spellings (camelCase and underscores) since this
just loops through all variables the object exposes. It is preferred to use the
ones with underscores when multiple exist.
In addition, if an instance has AWS Tags associated with it, each tag is a new
variable named:
- ec2_tag_[Key] = [Value]
Security groups are comma-separated in 'ec2_security_group_ids' and
'ec2_security_group_names'.

rax_flavor
rax_id

author: Jesse Keating
notes:
- Two environment variables need to be set, RAX_CREDS and RAX_REGION.
- RAX_CREDS points to a credentials file appropriate for pyrax
- RAX_REGION defines a Rackspace Public Cloud region (DFW, ORD, LON, ...)
