The describe_instances function is the base AWS::EC2 gem call we are using for this handler and returns a multi-level hash/array nest with a top level hash key of "reservationsSet".
The reservationSet has the following pseudo-xml form. Elements with the
All others are hash members and are references by element/key name.
To retrieve the imageId, for example, simply flatten the above structure by removing inapplicable items
Treat items as arrays and all other members as hash keys. Doing so, we can reference imageId value in the following manner:
