dnsmasq

Configuring dnsmasq to support your DNS server for OpenShift

Check /etc/resolv.conf to this:

nameserver 127.0.0.1

Edit the dnsmasq.conf file:

sudo vi /etc/dnsmasq.conf

Add these lines to the that file:

interface=eth0
no-hosts
addn-hosts=/etc/hosts.dnsmasq

Now create the database file /etc/hosts.dnsmasq for your DNS entries (use tab between ip and hostname):

192.168.0.1    master.thecloudlab.com
192.168.0.2    node1.thecloudlab.com

Restart the dnsmasq service

systemctl restart dnsmasq

Test it on client by doing direct and reverse resolution:

nslookup master.thecloudlab.com
nslookup 1.0.168.192.in-addr.arpa
