Maybe I'm misunderstanding the question, but you'd configure dnsmasq to forward 'cluster.local' to skydns and all other requests to your desired nameservers, place a file in /etc/dnsmasq.d/ like this
strict-order no-resolv domain-needed server=/cluster.local/172.30.0.1 server=/30.172.in-addr.arpa/172.30.0.1 server=4.4.4.4 server=8.8.8.8 Again, the installer does this for you automatically using a NetworkManager dispatcher script to configure dnsmasq. You can see what it does here https://github.com/openshift/openshift-ansible/blob/master/roles/openshift_node_dnsmasq/files/networkmanager/99-origin-dns.sh On Mon, Oct 3, 2016 at 3:41 AM, Fran Barrera <[email protected]> wrote: > Hi Scott, > > If I set dnsmasq in the node-config.yaml.
