+# 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'. 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.
