    groups: just_created
    foo: 42

# add a host with a non-standard port local to your machines
- add_host:
    name: "{{ new_ip }}:{{ new_port }}"

# add a host alias that we reach through a tunnel (Ansible <= 1.9)
- add_host:
    hostname: "{{ new_ip }}"
    ansible_ssh_host: "{{ inventory_hostname }}"
    ansible_ssh_port: "{{ new_port }}"

# add a host alias that we reach through a tunnel (Ansible >= 2.0)
