Doc Type: Release Note

DNS VIP is no longer a requirement for the installation, and is not in use in any of the components. This leaves only 2 IPs, the API VIP and INGRESS VIP. The install-config.yaml parameters for dns_vip will be ignored and will not fail the installation.

Description Roy Golan 2020-05-03 09:41:39 UTC
Description of problem:

DNS VIP is no longer needed for etcd, see Bug 1813003 for 4.5 and Bug 1813004 for 4.4

- remove mdns publishing etcd service records https://github.com/openshift/machine-config-operator/pull/1556

- remove DNS VIP from worker machines just like https://github.com/openshift/machine-config-operator/pull/1666

- remove DNS VIP specifics from the installer

- remote DNS vip specifics from openshift/api


Expected results:
Installation succeeds without DNS VIP and etcd records
