-

-# For server inside a VPC, using DNS names may not make sense. When an instance

-# private subnet, this should be set to 'private_ip_address', and Ansible must
-# be run from within EC2. The key of an EC2 tag may optionally be used; however
-# the boto instance variables hold precedence in the event of a collision.

-# will not be listed in the inventory until You set:
-# vpc_destination_variable = private_ip_address
-vpc_destination_variable = ip_address
-
-# The following two settings allow flexible ansible host naming based on a

-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
-
-If you're using boto profiles (requires boto>=2.24.0) you can choose a profile
-using the --boto-profile command line argument (e.g. ec2.py --boto-profile prod) or using
-the AWS_PROFILE variable:
-
-    AWS_PROFILE=prod ansible-playbook -i ec2.py myplaybook.yml
-
-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'.

-# 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'. The key of an EC2 tag
-# may optionally be used; however the boto instance variables hold precedence
-# in the event of a collision.
-destination_variable = public_dns_name
-
-# This allows you to override the inventory_name with an ec2 variable, instead
-# of using the destination_variable above. Addressing (aka ansible_ssh_host)
-# will still use destination_variable. Tags should be written as 'tag_TAGNAME'.
-#hostname_variable = tag_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 within EC2. The key of an EC2 tag may optionally be used; however
-# the boto instance variables hold precedence in the event of a collision.
-# WARNING: - instances that are in the private vpc, _without_ public ip address
-# will not be listed in the inventory until You set:
-# vpc_destination_variable = private_ip_address
-vpc_destination_variable = ip_address
-
-# The following two settings allow flexible ansible host naming based on a
-# python format string and a comma-separated list of ec2 tags.  Note that:
-#
-# 1) If the tags referenced are not present for some instances, empty strings
-#    will be substituted in the format string.
-# 2) This overrides both destination_variable and vpc_destination_variable.

-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
-
-If you're using boto profiles (requires boto>=2.24.0) you can choose a profile
-using the --boto-profile command line argument (e.g. ec2.py --boto-profile prod) or using
-the AWS_PROFILE variable:
-
-    AWS_PROFILE=prod ansible-playbook -i ec2.py myplaybook.yml
-
-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'.

-#   - 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

-# will still use destination_variable. Tags should be written as 'tag_TAGNAME'.
-#hostname_variable = tag_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 within EC2. The key of an EC2 tag may optionally be used; however
-# the boto instance variables hold precedence in the event of a collision.
-# WARNING: - instances that are in the private vpc, _without_ public ip address
-# will not be listed in the inventory until You set:
-# vpc_destination_variable = private_ip_address
-vpc_destination_variable = ip_address
-
-# The following two settings allow flexible ansible host naming based on a
-# python format string and a comma-separated list of ec2 tags.  Note that:
-#
-# 1) If the tags referenced are not present for some instances, empty strings

-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
-
-If you're using boto profiles (requires boto>=2.24.0) you can choose a profile
-using the --boto-profile command line argument (e.g. ec2.py --boto-profile prod) or using
-the AWS_PROFILE variable:
-
-    AWS_PROFILE=prod ansible-playbook -i ec2.py myplaybook.yml
-
-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'.

-# 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'. The key of an EC2 tag
-# may optionally be used; however the boto instance variables hold precedence
-# in the event of a collision.
-destination_variable = public_dns_name
-
-# This allows you to override the inventory_name with an ec2 variable, instead
-# of using the destination_variable above. Addressing (aka ansible_ssh_host)
-# will still use destination_variable. Tags should be written as 'tag_TAGNAME'.
-#hostname_variable = tag_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 within EC2. The key of an EC2 tag may optionally be used; however
-# the boto instance variables hold precedence in the event of a collision.
-# WARNING: - instances that are in the private vpc, _without_ public ip address
-# will not be listed in the inventory until You set:
-# vpc_destination_variable = private_ip_address
-vpc_destination_variable = ip_address
-
-# The following two settings allow flexible ansible host naming based on a
-# python format string and a comma-separated list of ec2 tags.  Note that:
-#
-# 1) If the tags referenced are not present for some instances, empty strings
-#    will be substituted in the format string.

-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
-
-If you're using boto profiles (requires boto>=2.24.0) you can choose a profile
-using the --boto-profile command line argument (e.g. ec2.py --boto-profile prod) or using
-the AWS_PROFILE variable:
-
-    AWS_PROFILE=prod ansible-playbook -i ec2.py myplaybook.yml
-
-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'.

-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
-
-If you're using boto profiles (requires boto>=2.24.0) you can choose a profile
-using the --boto-profile command line argument (e.g. ec2.py --boto-profile prod) or using
-the AWS_PROFILE variable:

-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'.

-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
-
-If you're using boto profiles (requires boto>=2.24.0) you can choose a profile
-using the --boto-profile command line argument (e.g. ec2.py --boto-profile prod) or using
-the AWS_PROFILE variable:
-
-    AWS_PROFILE=prod ansible-playbook -i ec2.py myplaybook.yml
-
-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'.

-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
-
-If you're using boto profiles (requires boto>=2.24.0) you can choose a profile
-using the --boto-profile command line argument (e.g. ec2.py --boto-profile prod) or using
-the AWS_PROFILE variable:
-
-    AWS_PROFILE=prod ansible-playbook -i ec2.py myplaybook.yml
-
-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'.

-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
-
-If you're using boto profiles (requires boto>=2.24.0) you can choose a profile
-using the --boto-profile command line argument (e.g. ec2.py --boto-profile prod) or using
-the AWS_PROFILE variable:
-
-    AWS_PROFILE=prod ansible-playbook -i ec2.py myplaybook.yml
-
-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'.

-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
-
-If you're using boto profiles (requires boto>=2.24.0) you can choose a profile
-using the --boto-profile command line argument (e.g. ec2.py --boto-profile prod) or using
-the AWS_PROFILE variable:
-
-    AWS_PROFILE=prod ansible-playbook -i ec2.py myplaybook.yml
-
-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

-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'.

-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
-
-If you're using boto profiles (requires boto>=2.24.0) you can choose a profile
-using the --boto-profile command line argument (e.g. ec2.py --boto-profile prod) or using
-the AWS_PROFILE variable:
-
-    AWS_PROFILE=prod ansible-playbook -i ec2.py myplaybook.yml
-
-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'.

-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
-
-If you're using boto profiles (requires boto>=2.24.0) you can choose a profile
-using the --boto-profile command line argument (e.g. ec2.py --boto-profile prod) or using
-the AWS_PROFILE variable:
-
-    AWS_PROFILE=prod ansible-playbook -i ec2.py myplaybook.yml
-
-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'.

-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
-
-If you're using boto profiles (requires boto>=2.24.0) you can choose a profile
-using the --boto-profile command line argument (e.g. ec2.py --boto-profile prod) or using
-the AWS_PROFILE variable:
-
-    AWS_PROFILE=prod ansible-playbook -i ec2.py myplaybook.yml
-
-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'.

-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
-
-If you're using boto profiles (requires boto>=2.24.0) you can choose a profile
-using the --boto-profile command line argument (e.g. ec2.py --boto-profile prod) or using
-the AWS_PROFILE variable:
-
-    AWS_PROFILE=prod ansible-playbook -i ec2.py myplaybook.yml
-
-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'.

-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
-
-If you're using boto profiles (requires boto>=2.24.0) you can choose a profile
-using the --boto-profile command line argument (e.g. ec2.py --boto-profile prod) or using
-the AWS_PROFILE variable:
-
-    AWS_PROFILE=prod ansible-playbook -i ec2.py myplaybook.yml
-
-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'.

-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
-
-If you're using boto profiles (requires boto>=2.24.0) you can choose a profile
-using the --boto-profile command line argument (e.g. ec2.py --boto-profile prod) or using
-the AWS_PROFILE variable:
-
-    AWS_PROFILE=prod ansible-playbook -i ec2.py myplaybook.yml
-
-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'.

-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
-
-If you're using boto profiles (requires boto>=2.24.0) you can choose a profile
-using the --boto-profile command line argument (e.g. ec2.py --boto-profile prod) or using
-the AWS_PROFILE variable:
-
-    AWS_PROFILE=prod ansible-playbook -i ec2.py myplaybook.yml
-
-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'.

-#   - vpc_destination_variable
-
-# This is the normal destination variable to use. If you are running Ansible

-# running Ansible from within EC2, then perhaps you want to use the internal

-# in the event of a collision.
-destination_variable = public_dns_name

-#hostname_variable = tag_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 within EC2. The key of an EC2 tag may optionally be used; however
-# the boto instance variables hold precedence in the event of a collision.
-# WARNING: - instances that are in the private vpc, _without_ public ip address
-# will not be listed in the inventory until You set:
-# vpc_destination_variable = private_ip_address
-vpc_destination_variable = ip_address
-
-# The following two settings allow flexible ansible host naming based on a
-# python format string and a comma-separated list of ec2 tags.  Note that:

-# 1) If the tags referenced are not present for some instances, empty strings

-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
-
-If you're using boto profiles (requires boto>=2.24.0) you can choose a profile
-using the --boto-profile command line argument (e.g. ec2.py --boto-profile prod) or using
-the AWS_PROFILE variable:
-
-    AWS_PROFILE=prod ansible-playbook -i ec2.py myplaybook.yml
-
-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'.

-# 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'. The key of an EC2 tag
-# may optionally be used; however the boto instance variables hold precedence
-# in the event of a collision.
-destination_variable = public_dns_name
-
-# This allows you to override the inventory_name with an ec2 variable, instead
-# of using the destination_variable above. Addressing (aka ansible_ssh_host)
-# will still use destination_variable. Tags should be written as 'tag_TAGNAME'.
-#hostname_variable = tag_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

-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
-
-If you're using boto profiles (requires boto>=2.24.0) you can choose a profile
-using the --boto-profile command line argument (e.g. ec2.py --boto-profile prod) or using
-the AWS_PROFILE variable:
-
-    AWS_PROFILE=prod ansible-playbook -i ec2.py myplaybook.yml
-
-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'.

-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
-
-If you're using boto profiles (requires boto>=2.24.0) you can choose a profile
-using the --boto-profile command line argument (e.g. ec2.py --boto-profile prod) or using
-the AWS_PROFILE variable:
-
-    AWS_PROFILE=prod ansible-playbook -i ec2.py myplaybook.yml
-
-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'.

-# 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'. The key of an EC2 tag

-# in the event of a collision.
-destination_variable = public_dns_name

-# This allows you to override the inventory_name with an ec2 variable, instead
-# of using the destination_variable above. Addressing (aka ansible_ssh_host)
-# will still use destination_variable. Tags should be written as 'tag_TAGNAME'.
-#hostname_variable = tag_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 within EC2. The key of an EC2 tag may optionally be used; however
-# the boto instance variables hold precedence in the event of a collision.
-# WARNING: - instances that are in the private vpc, _without_ public ip address
-# will not be listed in the inventory until You set:
-# vpc_destination_variable = private_ip_address
-vpc_destination_variable = ip_address
-
-# The following two settings allow flexible ansible host naming based on a
-# python format string and a comma-separated list of ec2 tags.  Note that:
-#
-# 1) If the tags referenced are not present for some instances, empty strings
-#    will be substituted in the format string.

-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
-
-If you're using boto profiles (requires boto>=2.24.0) you can choose a profile
-using the --boto-profile command line argument (e.g. ec2.py --boto-profile prod) or using
-the AWS_PROFILE variable:
-
-    AWS_PROFILE=prod ansible-playbook -i ec2.py myplaybook.yml
-
-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'.

-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
-
-If you're using boto profiles (requires boto>=2.24.0) you can choose a profile
-using the --boto-profile command line argument (e.g. ec2.py --boto-profile prod) or using
-the AWS_PROFILE variable:
-
-    AWS_PROFILE=prod ansible-playbook -i ec2.py myplaybook.yml
-
-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'.

-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
-
-If you're using boto profiles (requires boto>=2.24.0) you can choose a profile
-using the --boto-profile command line argument (e.g. ec2.py --boto-profile prod) or using
-the AWS_PROFILE variable:
-
-    AWS_PROFILE=prod ansible-playbook -i ec2.py myplaybook.yml
-
-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

-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'.

-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
-
-If you're using boto profiles (requires boto>=2.24.0) you can choose a profile
-using the --boto-profile command line argument (e.g. ec2.py --boto-profile prod) or using
-the AWS_PROFILE variable:
-
-    AWS_PROFILE=prod ansible-playbook -i ec2.py myplaybook.yml
-
-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'.

-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
-
-If you're using boto profiles (requires boto>=2.24.0) you can choose a profile
-using the --boto-profile command line argument (e.g. ec2.py --boto-profile prod) or using
-the AWS_PROFILE variable:
-
-    AWS_PROFILE=prod ansible-playbook -i ec2.py myplaybook.yml
-
-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'.

-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
-
-If you're using boto profiles (requires boto>=2.24.0) you can choose a profile
-using the --boto-profile command line argument (e.g. ec2.py --boto-profile prod) or using
-the AWS_PROFILE variable:
-
-    AWS_PROFILE=prod ansible-playbook -i ec2.py myplaybook.yml
-
-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'.

-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
-
-If you're using boto profiles (requires boto>=2.24.0) you can choose a profile
-using the --boto-profile command line argument (e.g. ec2.py --boto-profile prod) or using
-the AWS_PROFILE variable:
-
-    AWS_PROFILE=prod ansible-playbook -i ec2.py myplaybook.yml
-
-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'.

-GCE external inventory script
-=================================
-
-Generates inventory that Ansible can understand by making API requests
-Google Compute Engine via the libcloud library.  Full install/configuration
-instructions for the gce* modules can be found in the comments of
-ansible/test/gce_tests.py.
-
-When run against a specific host, this script returns the following variables
-based on the data obtained from the libcloud Node object:
- - gce_uuid
- - gce_id
- - gce_image
- - gce_machine_type
- - gce_private_ip
- - gce_public_ip
- - gce_name
- - gce_description
- - gce_status
- - gce_zone
- - gce_tags
- - gce_metadata
- - gce_network
-
-When run in --list mode, instances are grouped by the following categories:
- - zone:
-   zone group name examples are us-central1-b, europe-west1-a, etc.
- - instance tags:
-   An entry is created for each tag.  For example, if you have two instances
-   with a common tag called 'foo', they will both be grouped together under
-   the 'tag_foo' name.
- - network name:
-   the name of the network is appended to 'network_' (e.g. the 'default'
-   network will result in a group named 'network_default')
- - machine type
-   types follow a pattern like n1-standard-4, g1-small, etc.
- - running status:
-   group name prefixed with 'status_' (e.g. status_running, status_stopped,..)
- - image:
-   when using an ephemeral/scratch disk, this will be set to the image name
-   used when creating the instance (e.g. debian-7-wheezy-v20130816).  when
-   your instance was created with a root persistent disk it will be set to
-   'persistent_disk' since there is no current way to determine the image.
-
-Examples:
-  Execute uname on all instances in the us-central1-a zone
-  $ ansible -i gce.py us-central1-a -m shell -a "/bin/uname -a"
-
-  Use the GCE inventory script to print out instance specific information
-  $ contrib/inventory/gce.py --host my_instance

-#   - destination_variable
-#   - vpc_destination_variable
-
-# This is the normal destination variable to use. If you are running Ansible

-#hostname_variable = tag_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 within EC2. The key of an EC2 tag may optionally be used; however
-# the boto instance variables hold precedence in the event of a collision.
-# WARNING: - instances that are in the private vpc, _without_ public ip address
-# will not be listed in the inventory until You set:
-# vpc_destination_variable = private_ip_address
-vpc_destination_variable = ip_address
-
-# The following two settings allow flexible ansible host naming based on a

-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
-
-If you're using boto profiles (requires boto>=2.24.0) you can choose a profile
-using the --boto-profile command line argument (e.g. ec2.py --boto-profile prod) or using
-the AWS_PROFILE variable:
-
-    AWS_PROFILE=prod ansible-playbook -i ec2.py myplaybook.yml
-
-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'.

+GCE external inventory script
+=================================
+
+Generates inventory that Ansible can understand by making API requests
+Google Compute Engine via the libcloud library.  Full install/configuration
+instructions for the gce* modules can be found in the comments of
+ansible/test/gce_tests.py.
+
+When run against a specific host, this script returns the following variables
+based on the data obtained from the libcloud Node object:
+ - gce_uuid
+ - gce_id
+ - gce_image
+ - gce_machine_type
+ - gce_private_ip
+ - gce_public_ip
+ - gce_name
+ - gce_description
+ - gce_status
+ - gce_zone
+ - gce_tags
+ - gce_metadata
+ - gce_network
+ - gce_subnetwork
+
+When run in --list mode, instances are grouped by the following categories:
+ - zone:
+   zone group name examples are us-central1-b, europe-west1-a, etc.
+ - instance tags:
+   An entry is created for each tag.  For example, if you have two instances
+   with a common tag called 'foo', they will both be grouped together under
+   the 'tag_foo' name.
+ - network name:
+   the name of the network is appended to 'network_' (e.g. the 'default'
+   network will result in a group named 'network_default')
+ - machine type
+   types follow a pattern like n1-standard-4, g1-small, etc.
+ - running status:
+   group name prefixed with 'status_' (e.g. status_running, status_stopped,..)
+ - image:
+   when using an ephemeral/scratch disk, this will be set to the image name
+   used when creating the instance (e.g. debian-7-wheezy-v20130816).  when
+   your instance was created with a root persistent disk it will be set to
+   'persistent_disk' since there is no current way to determine the image.
+
+Examples:
+  Execute uname on all instances in the us-central1-a zone
+  $ ansible -i gce.py us-central1-a -m shell -a "/bin/uname -a"
+
+  Use the GCE inventory script to print out instance specific information
+  $ contrib/inventory/gce.py --host my_instance
