found a solution myself
- name: find interface without an ip
set_fact:
desired_interface_name: "{{ item }}"
when:
hostvars[inventory_hostname]['ansible_'+item].ipv4|length == 0
# ansible_{{ item }}.ipv4 is defined and (ansible_{{ item }}|length>0)
with_items:
"{{ ansible_interfaces }}"
it works. although it seems a bit counterintuitive...
why not the first way???
