Description David Eads 2019-11-07 12:55:52 UTC
This bug was initially created as a copy of Bug #1764313

I am copying this bug because: 

metrics for the kube-apiserver include critical metrics for determining pieces of cluster configuration and state back through telemetry.  it's also the generic mechanism used by many other operators.

found by service catalog and console who have each tried to shim around the problem.

The /metrics endpoint should have an e2e test to validate that it responds with prometheus metrics.  The key metrics is console_url.  

The console operator is not currently reporting console_url on master (4.3).
