RE: openshift dns as delegated domain

Title: Re: openshift dns as delegated domain


No, I’ve discovered the openshift_use_dnsmasq=False ansible option and now is the openshift DNS the one listening on port 53, but seems still not accessible from our domain controller as an standard DNS server, so I’ve resigned from this and using a wildcard DNS entry that at least allow me to progress.

I think you need something like this called split horizon.


That is exactly my question, which is much simpler than the serverfault question & answer, as I don't want to override any authoritative answers, just to get them.

What I would do is the following.

.) add
cluster.local zone in your primary dns server
.) point the ns entries for master01

In particular, how to do this two steps at least, that I know how to do for standard dnsmasq as authoritative server, but not as "proxy" for the openshift one.
