Description OpenShift BugZilla Robot 2021-03-05 18:09:06 UTC
+++ This bug was initially created as a clone of Bug #1934773 +++

Description of problem:
The ingress operator's canary controller periodically probes the canary endpoint over HTTP. The canary route is an edge terminated route that redirects insecure traffic. Some customers, such as one mentioned in https://bugzilla.redhat.com/show_bug.cgi?id=1932401, expose the default ingress controller via an external load balancer that drops _all_ traffic to port 80, thus making an http -> https redirect impossible for the canary route.

The canary route should send probe requests over https only to mitigate this issue.
