group var inside jinja loop

Hi,

having a jinja loop

{% for host in groups[‘server_group’] %} --dns={{ hostvars[host][‘ansible_eth0’][‘ipv4’][‘address’] }} {% endfor %}

i want to change “eth0” with a group_var as the interface some times differs. I know i could do a “ansible_eth1” in the template but i had to do this in a lot of places so i thought using group_var (interface) would be ok.

I tried {% for host in groups[‘server_group’] %} --dns={{ hostvars[host][‘ansible_{{interface}}’][‘ipv4’][‘address’] }} {% endfor %}

and a lot of other but always ended with a error. How can i use a group_var inside of this loop?

Cheers,

Mike

solved it with

{% for host in groups[‘server_group’] %} --dns={{ hostvars[host][nic].ipv4.address }} {% endfor %}

where nic is a group var.
