Description Ben Nemec 2020-05-27 03:45:17 UTC

Description of problem: The baremetal platform no longer uses the DNS VIP, thanks to changes in the way etcd clustering works. However, there is still a DNS VIP item in the baremetal install-config in the installer. Worse, it is a mandatory setting because previously the install could not complete without it. We need to remove that setting.


Version-Release number of selected component (if applicable): 4.5


How reproducible: Always


Steps to Reproduce:
1. Run baremetal install without setting DNS VIP in install-config

Actual results: The install-config validations will fail.


Expected results: Deployment proceeds normally.


Additional info: DNS VIP usage was removed in https://github.com/openshift/machine-config-operator/pull/1569

(ocp-edge-qe-venv) [root@titan44 linchpin-workspace]# oc version
Client Version: 4.5.0-202005291417-9933eb9

Needs manual installation.

Once the install-config.yaml has been created on the provisionhost,

I've deleted the dnsVIP record & let the installation to continue.

The deployment was successful.
