# 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_excluded_zones' as a comma-separated list.
|

# route53_excluded_zones = samplezone1.com, samplezone2.com

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'
|
||||
|
||||
This script also assumes there is an ec2.ini file alongside it. To specify a
|
||||
different path to ec2.ini, define the EC2_INI_PATH environment variable:
|
||||
|
||||
export EC2_INI_PATH=/path/to/my_ec2.ini
|
||||
|
||||
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'.
