Re: Configuring Private DNS Zones and Upstream Nameservers in Openshift



Thanks Clayton. This is very useful feature for clients to manage their dns and helps a lot  for service discovery type integrations.

Probably have to wait until 3.9.  We also want to move to coredns, but that could take longer.

Is it possible like described in kubernetes?

We have few clients where they configured their own consul based DNS server and not suing service discovery provided by Openshift. We build a custom solution by adding these external zones and IP addresses to dnsmasq.conf. This approach working but having few failures since it has to first check cluster zones by honoring the order specified in /etc/resolve.conf and then forward to these external DNS severs.

 

I saw a solution in Kubernetes 1.9 as an alpha feature  by letting clients to configure their own DNS settings in POD definitions.

Openshift clients need to wait till 3.9? or is there any way currently to solve this problem?
