Thanks, Dick.
You're right. You definitely need to access the system. I created a way
to print the info from the system using the setup module. It seems to work
well:
- name: Collect setup facts
setup:
gather_subset:
- all
with_items:
- "{{ec2.results[0].instances}}"
delegate_to: '{{ item.private_ip_address }}'
register: ansible_setupfacts
