Hi, I have two inventories, each for test an production. And I call ansible(-playbook) explicitly with one of these, to not mix things up. 🙂 (Things like IP configuration differ from test and production.) The inventory has group names ending in "-test" or "-prod" too, on which I could check too. # test: [webserver-test] foo1 server2 # production [webservers-prod] foo2 server1 How can I check in the task and in jinja templates, if the host is in test or production? I asked something related in 2013 and got "when: inventory\_hostname in groups.webservers-test" as an answer. But this results in a fatal "error while evaluating conditional: inventory\_hostname in groups.webservers-test" I could set this as a group:var for all, like: # test [all:vars] env="test" Is this the best way to do this?

That works fine for me - [all:vars] in an inventory, but I use the same group names across all inventories for consistency. I think this could bite me in the future with dynamic inventories etc. that may make it a little harder to do that, but for now it works great. ---

​You inventory has webserver-test, not webserver\*s\*-test :)​ But next thing would be, variable names cannot have dashes, so you would need to rewrite you conditional using a string:    when: inventory\_hostname in groups["webservers-test"] ---

I like the [all:vars] way better now, I think. Marc
