inventory file for playbooks with only uri calls

[Nicholas Britton]

I am working on a set of playbooks for a hitachi storage automation.    They utilize a cmrest server, that manages the connection to each storage array.   So all of the tasks are ran on the localhost to the same url base, but there is a var in the path that indicates what storage array to run against.    

I was looking at the inventory file as an option to set the vars for each storage array.   Each storage array would be a group, but since they all have localhost, the var overwrites because it belongs to multiple groups.

Does anyone have an idea of how i can achieve this or something similar to this?  

Here is an example of the inventory file i started with:

[amsterdam]
localhost


[amsterdam:vars]
ui=886000428027
hostss=esx001,esx002,esx003


[singapore]
localhost


[singapore:vars]
ui=44444


[all:vars]
baseurl="https://10.123.123.123:23351/ConfigurationManager/v1/"
