The name of the current inventory file in use is stored in the
"inventory_file" variable name, so you could check that. Beyond that, there
are two other options:
1. Use --extra-vars to specify the target environment, for example:
--extra-vars="inventory=qa"
2. The group_vars location is based on the location of the inventory file,
so you could do something like this:
qa/group_vars/all:
inventory=qa
prod/group_vars/all:
inventory=production
The qa/hosts and prod/hosts would contain your different inventories, so
you'll get output like this:
$ cat play.yml
- hosts: all
gather_facts: no
tasks:
- name: show the variable
debug: var=inventory
$ ansible-playbook play.yml -i prod/hosts
PLAY [all]
********************************************************************
TASK: [show the variable]
*****************************************************
ok: [you] => {
"inventory": "production"
}
PLAY RECAP
********************************************************************
you : ok=1 changed=0 unreachable=0 failed=0
$ ansible-playbook play.yml -i qa/hosts
PLAY [all]
********************************************************************
TASK: [show the variable]
*****************************************************
ok: [me] => {
"inventory": "qa"
}
PLAY RECAP
********************************************************************
me : ok=1 changed=0 unreachable=0 failed=0
Hope that helps.
