Description Michal Fojtik 2021-08-23 11:32:13 UTC

Description of problem:

When the DNS server is not reachable or DNS itself is not working, we give this message to users/admins:

Operator unavailable (OAuthServerRouteEndpointAccessibleController_EndpointUnavailable): OAuthServerRouteEndpointAccessibleControllerAvailable: Get "https://oauth-openshift.apps.ci-op-6izkt7mz-16f7c.gcp-2.ci.openshift.org/healthz": dial tcp: lookup oauth-openshift.apps.ci-op-6izkt7mz-16f7c.gcp-2.ci.openshift.org on 172.30.0.10:53: no such host


There is no hint here that the problem is DNS server except the :53 port.

I’m adding UpcomingSprint, because I was occupied by fixing bugs with higher priority/severity, developing new features with higher priority, or developing new features to improve stability at a macro level. I will revisit this bug next sprint.

Ah, as per this, moving to VERIFIED directly. The code checks if the error contains ":53: no such host" and if yes then it appends "(this is likely result of malfunctioning DNS server)".
