I'm trying to dynamically set /etc/hosts based on the ipv4 address assigned
to all the interfaces on a host... my template reads as such
127.0.0.1 localhost.localdomain localhost
{% for item in ansible_interfaces if item != 'lo' %}
{{ 'ansible_' + item + '.ipv4.address' }} {{ lookup('dig', 'ansible_' +
item + '.ipv4.address' + '/PTR') }}
{% endfor %}
which results in :
127.0.0.1 localhost.localdomain localhost
ansible_eth1.ipv4.address NXDOMAIN
ansible_eth0.ipv4.address NXDOMAIN
I've tried several iterations, but I'm struggling to find the proper syntax
to get the file to write as expected... is this possible? Any suggestions
greatly appreciated.
