# 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. |

||||
|

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'. |
