[markgoddard]

[cavamagie]

yes srry you can use this kind of info

• role: MichaelRigart.interfaces interfaces_ether_interfaces:
  • device: eth1 bootproto: static address: 192.168.1.150 netmask: 255.255.255.0 gateway: 192.168.1.1 dnsnameservers: 192.0.2.1 192.0.2.2 dnssearch: example.com mtu: 9000 route:

and dnsnameservers: 192.0.2.1 192.0.2.2 work in debian with resolvconf but in redhat the value is not used in the configuration

grep -r dnsnameservers * README.md: dnsnameservers: 192.0.2.1 192.0.2.2 README.md: dnsnameservers: 192.0.2.1 192.0.2.2 README.md: dnsnameservers: 192.168.1.1 templates/ethernet_Debian.j2:{% if item.dnsnameservers is defined %} templates/ethernet_Debian.j2:dns-nameservers {{ item.dnsnameservers }}

Looks like you can set DNS1 and DNS2 in interface config files. Feel free to submit a PR.

ah ok we can add an

{% if item.dnsnameservers is defined %} DNS={{ item.dnsnameservers }} {% endif %}

to jnj file?

[markgoddard]

That might work for a single server, for two servers you would need to use DNS1 and DNS2. Try it out.

[cavamagie]

thanks @markgoddard

{% if item.dnsnameservers is defined %} {% if item.dnsnameservers.split(' ')[-2] is defined %} DNS2={{ item.dnsnameservers.split(' ')[-2]}} {% endif %} {% if item.dnsnameservers.split(' ')[-1] is defined %} DNS1={{ item.dnsnameservers.split(' ')[-1]}} {% endif %} {% else %} DNS1=xxxxx DNS2=xxxxx {% endif %}

[markgoddard]

How about:

{% if item.dnsnameservers is defined %} {% for dns_server in item.dnsnameservers.split(' ')[:2] %} DNS{{ loop.index + 1 }}={{ dns_server }} {% endfor %} {% endif %}

[cavamagie]

thank you!
