superfluous logging when using ssl-passthrough

[abh]

For an ingress configured with ssl-passthrough I have a TLS section (otherwise it didn't listen to port 443), but no secretName (because the secret isn't here...). Every few seconds the controller logs:

controller.go:1043] host xyz.example.com is listed on tls section but secretName is empty. Using default cert

@abh if you use ssl-passthrough you don't need the tls section. It's ok to not see a listen in port 443.

@abh I will remove this log in the next release

Great, thank you. An alternative would be to log that the tls section is unnecessary/unused. :-)

Closing. Fixed in #1031
