I don’t think Ansible will work with this scenario.

I want to iterate through every ansible role and host as a flat index.

Right now the groups variable is what I’m focused on. Which is:

group0:

- host0

- host1

group1:

- host2
- host3

I want to process it as:

group0, host0  
group0, host1  
group1, host2  
group1, host3

… but I don’t think this is possible. Is there a ‘flatten’ I can use?

with\_dict and with\_subelements won’t work.

with\_subelements complains that it expects a map with a key to iterate from.
