We need one more record like following added into both base domain and private zone.

*.apps.jliu.origin-gce.dev.openshift.com.                 A     300

Since the worker node has not public ip, so an lb with public ip also need to be created in step [Create DNS entries and load balancers]

This seems like similar to what's being asked in https://bugzilla.redhat.com/show_bug.cgi?id=1715635

PR for the above one is https://github.com/openshift/installer/pull/2221

Comment 2 liujia 2019-08-29 07:26:40 UTC
Just have a try on the latest 4.2.0-0.nightly-2019-08-29-041601, the ingress operator can generate the lb and *.apps records successfully without extra config this time. So i'not sure if it's a bug for ingress operator on 4.2.0-0.nightly-2019-08-21-235427 or just lukcy as https://bugzilla.redhat.com/show_bug.cgi?id=1715635#c5 said.

So keep the bug open to track if extra steps needed for *.apps records on upi/gcp process. Since it's not blocking qe's test now, adjust severity and priority.

Comment 3 Jeremiah Stuever 2019-08-29 16:19:09 UTC
Perhaps because of https://github.com/openshift/cluster-ingress-operator/pull/286

Comment 4 Jeremiah Stuever 2019-08-29 18:15:17 UTC
I just tried with latest from installer (master branch) and I still see the issue. The ingress-router load balancers are not getting created, probably because there are no compute nodes. The DNS entries are not created until the load balancers exist. Therefore, they rely on compute nodes to exist as well. Perhaps the "luck" is having added compute nodes to the cluster?

I have a mostly ready PR to clarify how to add the compute nodes as well as how to add the apps DNS records manually. Will be posted as soon as I get it cleaned up.
