Pattern First after intersection

I can’t figure out how to create the correct pattern. Currently I am about to get a list of three zookeeper boxes from the pattern tag_zookeeper:&tag_env_test.What I need is to get the first (really just any 1) one that results from that list.

Is there any way to do that?

Cheers,

Edgardo

tag_zookeeper:&tag_env_test[0]

That doesn’t work. That gets the first in the tag_env_test group and intersects with the lst of tag_zookeeper.

(lookup(‘inventory_hostnames’, ‘tag_zookeeper:&tag_env_test’)|list)[0]

That didn’t seem to work in a playbook setting hosts

hosts:(lookup(‘inventory_hostnames’, ‘tag_zookeeper:&tag_env_test’)|list)[0]

any suggestions?

I should have been more explicit:

hosts: “{{(lookup(‘inventory_hostnames’, ‘tag_zookeeper:&tag_env_test’)|list)[0]}}”
