You'd have to define it yourself in your plays somewhere
Several ways present themselves:
- Group customers together by customer name and use the group name.
- Define the customer directly in the inventory. Generally it isn't
recommended to define variable there, but I think this is one of the few
case where it does make sense. Sort of like this:
acme_web_server ansible_ssh_host=1.2.3.4 customer=acme
{{ customer }} then is available for that host whenever the host is in scope
One thing you'll find with ansible is there's always a way to do
something, often more than one way (like perl). And all ways often make
sense (unlike perl)
