Add an example of template logic to chose an IP by interface name priority.

{%- if   'bond0' in vars.sys.interfaces %}
    # 'bond0' in vars.sys.interfaces
    {%- set my_ip = vars.sys['ipv4[bond0]'] %}
{%- elif 'eth0' in vars.sys.interfaces %}
    # Found eth0 as default interface
    {%- set my_ip = vars.sys['ipv4[eth0]'] %}
{%- else %}
    # Not found bond0 or eth0, using default sys.ipv4
    {%- set my_ip = vars.sys.ipv4 %}
{%- endif %}
