define common group for multiple inventory files?

Hi,

we have to support several environments (Dev, Test, Preview, Prod) - so we have the following structure for our (static) inventory:

`
inventory
– group
---- dev

  • hosts
  • group_vars
  • host_vars

---- test

  • hosts
  • group_vars
  • host_vars

---- prod

  • hosts
  • group_vars
  • host_vars

`

The hosts file looks like

`
[weblogic]
domain-1
domain-2

domain-5

[domain-1]
myserver1.com

[domain-2]
myserver2.com

[domain-5]
myserver5.com

`

=> The [weblogic] parent group always has the same entries, while the [domain-x] groups have 1…N servers depending on the environment.

Is there a way to share this “common weblogic group” over all inventories ?
I want to prevent repeating this group definition.

Thanx for any advice,

Torsten
