Hi,  
I am trying to take backup of some REST API dump on target nodes .  
Assume that 3 nodes in cluster and 1 is controller node from where we invoke playbook,  
I need that backup on controller node as well. I can use modules like copy, fetch etc. but how i will know the  
hostname or IP dynamically of controller node.
