Added support for multiple sets of domains

@unguiculus with @krancour unfortunately stepping away from Traefik review duties, do you know how to get another person in the OWNERS file assigned to this PR?

dtomcej · 2018-06-29T15:51:11Z

I have been trying! but I'm not part of the proper org it seems...

krancour · 2018-06-30T17:55:46Z

@dtomcej apart from being in the owner's file, you also need to be in the Kubernetes github org. I hadn't realized that you and other Traefik maintainers were not.

The process for requesting membership is here: https://github.com/kubernetes/community/blob/master/community-membership.md#requirements

You can use me as a sponsor. If you know anyone else who's already a member, as them as well.

Tested on my development kub8s -> Works like a charm 👏 👏 👏 👏

Hi @billimek & @krancour. Any chance to get this approved ?

+    # List of sets of main and (optional) SANs to generate for
+    # for wildcard certificates see https://docs.traefik.io/configuration/acme/#wildcard-domains

I think the examples in this section should be commented out - this is the norm for examples and avoids you accidentally attempting to request certs for example domains.

Finally some feedback, thank you @grugnog!

Changes pushed.
