I have the following yml file:

# Kill RTS components

It was explained to me by one of my co-workers that “{{ host }}” doesn’t exist and there should probably be a failure prior to executing tasks/realtime\_system/kill.yml.

Is there a way I can get the children of realtime\_system\_components and use that within the vars\_files?

“{{ host }}” doesn’t exist, but “{{ inventory\_hostname }}” which is the name of the host in the host loop and “{{ ansible\_hostname }}” which is the name of the discovered hostname of the the host, does exist.

“Is there a way I can get the children of realtime\_system\_components and use that within the vars\_files”

Sort of. You can see what machines are in any group:

- debug: var=item  
with\_items: groups.webservers
