Hi!

Thanks for your feedback. First of all, I’ve just dropped a new update that will create a subdomain if you specify one on the environment variables that does not exist. That was a cool feature I use a lot on previous Docker images I used with other providers.

I don’t know if that solves your problem (I think not), but I will be glad of hearing your issue. I don’t know if you want to put a single * or something like that in the field of subdomains to update, instead of writing all down (sub1, sub2, sub3, sub4, sub5).

Regarding IPv4 and IPv6, I’m working on implement IPv6 now, I want that to be part of the next release (within one month), as well as multi-arch images. Definitely, I will try to update both at the same time as you want.

Thanks again!
