マルチサイトDockerfileの問題

ガイドを読んで適用しようとしましたが、app.yml ファイルは以下のようになりました。間違いがあるかもしれません。Docker のみを使用しています。やりたいことは、仮想サーバー上で 2 つのサイトを開設することです。1. サイト名: dursuncan.com、2. サイト名: forum.tekno-byte.com app.yml ファイルはどのように編集すべきでしょうか？

   # ./launcher rebuild app

そのようなコンテナを2つ用意し、その前にリバースプロキシを配置する必要があります。app.yml を app2.yml にコピーして編集してください。Discourse と同じマシン上で他の Web サイトを実行する場合は こちら、同じプラグインとメールサーバーを使用できる場合は、リバースプロキシなしで Let’s Encrypt を用いたマルチサイト構成 こちら を参照してください。

LEMPサーバーで最初の手法を使用しました。この手法をDocker経由で実行することは可能でしょうか？また、Dockerの外にNginxサーバーをインストールするとパフォーマンスに影響はありますか？

はい、可能です。各フォーラムごとに Docker イメージを用意します。

外部のリバースプロキシも Docker コンテナとして実行できます。

ほとんどありません。

Nginx をインストールしました。設定も行いました。app.yml ファイルを編集しました。しかし、rebuild プロセスが失敗します。何が問題なのでしょうか？
