はい、レビュー待ちのプルリクエストをこちらで開いています。

> <https://github.com/discourse/discourse_docker/pull/992>
>
> add comma-separated DISCOURSE\_HOSTNAME\_ALIASES to handle multiple aliases
> for l…etsencrypt domain generation over env vars
> 
> FIX: add letsencrypt renew location for .well-known and allow for multi-domain renewal
> Do not redirect to https on .well-known location for any domain
> so letsencrypt cert renewals can work properly.
> 
> FIX: better listening for ipv6 for ipv4 only
> Current letsencrypt assumes ipv6 in config. Check for ipv6 before listening
