Good morning,

My playboy works on all hosts and is invoked like this:

Ansible-playbook -l customer main.yml

The customer group in the inventory is done this way:

[Customer]  
customer-ecas1  
customer-ecas2  
customer-ecas3  
…  
customer-ecasn  
customer-cti1  
…  
…  
customer-CTIN

What I would like to do is:

- First check all customer-ecasx servers
- If at least one of the customer-ecas servers has a certain feature then execute the operation on customer-cti1

it’s possible to do it?

Thank you.
