Set up Let’s Encrypt with multiple domains / redirects

Hey everyone, just following up, multi domains are now merged - in the latest version of discourse_docker, you can now include the ssl and letsencrypt templates and setup env vars of the form DISCOURSE_HOSTNAME_ALIASES: domain.com,other.domain.com to set up alternate hostnames. Your site will additionally pull the configured hostnames with the cert request with no additional config changes

リダイレクトを回避するためにNginxを微調整する必要があるかもしれませんが、Dockerセットアップの詳細はわかりません。
