Doc Type: Bug Fix
Doc Text:
Cause: OpenShift 4.8 added an API for customizing platform routes, such as the routes for OpenShift console and OAuth. This API includes status and spec fields in the cluster ingress configuration for reporting the current host names of customizable routes as well as the user's desired host names for these routes, respectively. The API also defined constraints for these values. These constraints were overly restrictive and excluded some valid potential host names, such as host names with top-level domains (TLDs) that contained decimal digits. Consequence: The overly restrictive validation for the new API had two important consequences. First, the restriction on spec prevented users from specifying custom host names that should have been permitted. Second, the restriction on status prevented users from being able to install clusters with domains that should have been permitted, because the operators that report the status would fail when trying to update status. For example, installing a cluster with the domain m3558001.ocptest1 would fail because of the "1" in the TLD. Fix: The constraints on host names in the new API were relaxed to allow all host names that are valid for routes. Result: OpenShift once again allows users to use cluster domains with TLDs that contain decimal digits. OpenShift additionally allows users to customize the console and OAuth routes using any host names that are valid for routes.

Verified with the latest CI image. With the fix in place, the error no more occurs with the component route containing numeric values in the hostname:
