RE: resolv.conf question- Digest, Vol 50, Issue 91 -



I changed my node-config.yaml to my master ip as shown below and restarted the node service. When new pods were deployed (or redeploy existing ones) the resolv.conf got updated with my master ip first, then my external dns. We're using external dns and not dnsmasq so I'm not sure if this will work for you?

@openshift node]# cat node-config.yaml
allowDisabledDocker: false
apiVersion: v1
dnsDomain: cluster.local
dnsIP: master_ip

systemctl restart atomic-openshift.node

Hi All,

In my environment, the master is the DNS server (dnsmasq) and my problem is that I have very slow resolution. The resolv.conf of pods is:

nameserver 172.30.0.1
nameserver master_ip

I need to change this conf adding first the master IP or add a options timeout because the slow is because try first with kubernetes dns and 10 seconds later try with dns master. I've followed this guide
https://access.redhat.com/solutions/2215521 but not change anything.

Any helps?
