AWS EC2 Instance List Version 1

This handler will be used primarily in a loop to iterate over multiple EC2 image instances. In order to be used by the Loop handler, a single value is returned as an escaped XML string. called "Instance List".

The Instance List will have the following format: i-01234567 i-abcdefgh i-0123abcd

To setup the Loop handler, refer to the Instance List from this handler for 'Data Source' and use '/instances/instance'as the 'Variable Path'.

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 tag are array members and are referenced by numerical index.

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:

@baseawsobject.reservationSet.item[index].instancesSet.item[index].imageId
