Hi,

I would like to define a dict in group\_vars/all.yml where a key inside this dict would consist of a fixed string concatened to the result of : “{{ hostvars[inventory\_hostname][‘ansible\_hostname’] }}”.

This should looks like following:

✘ root@lab:~/playbook# cat group\_vars/all.yml

No one for this?  
I’m also getting this problem, it’d be nice if we could get some clarification.

Thanks!
