Description Roy Golan 2020-06-11 11:56:46 UTC

DNS VIP is no longer needed, and is not in use to form the etcd cluster.

- remove it from installconfig, ignore if passed
- remove it from platform
- remove the wizard question for dns_vip
- remove from platform documents under docs/user/ovirt

Comment 1 Roy Golan 2020-06-11 12:19:53 UTC

also remove the openshift/api struct field - https://github.com/openshift/api/blob/95abe2d2f4223d5931e418bf8e4d3773d16b42c0/config/v1/types_infrastructure.go#L397

Comment 3 Sandro Bonazzola 2020-06-18 06:43:22 UTC

due to capacity constraints we will be revisiting this bug in the upcoming sprint

We cannot remove this field at this moment, otherwise will break the API compatibility. In one year from now, we will able to do that (for all platforms).

Comment 6 David Eads 2020-07-10 13:00:27 UTC

We don't want to immediately remove the field because that can cause upgraded clusters to fail.  Instead, we should update the API doc to deprecate the field and indicate that the value is no longer set and no longer honored. This leaves old clusters with previous value set, but ensures that new clusters cannot make use of it.

One year from now, we can reassess removal or force clearing of the value to bring every cluster in line.

Comment 8 Jan Zmeskal 2020-09-29 11:27:13 UTC

Verified with 4.6.0-0.nightly-2020-09-28-212756

Verification steps:
1. Check https://github.com/openshift/installer/blob/master/docs/user/ovirt/install_ipi.md to see if the reference to DNS VIP has been removed
2. Run openshift-install create install-config and go through the wizard. Make sure it does not ask for DNS VIP.
