Thanks! This is getting better and better:
Modifying my playbook like this:
- name: iterate over hosts
command: ping -c 1 {{ hostvars[item]["ansible_bond1.2108"].ipv4.address }}
with_items: groups.storages
ignore_errors: true
tags: gz
Now I get:
< TASK: swift-proxy | iterate over hosts >

Any idea?
Thanks again in advance :)
