我正在尝试通过 Dokku 在 Docker 中运行 Forem 论坛软件。我遵循了以下指南：https://dev.to/akhilnaidu/self-hosting-forem-dev-on-linux-using-t2d-2kgh
域名 evstalkin.com 的 A 记录指向 VPS 的 IP 地址。
现在我的 VPS（Ubuntu 22.04、Afterburst.com）上运行着两个 Docker 容器，浏览器中显示了一条错误消息。（“很抱歉，但出了点问题。”并且它的 CSS 比通常的 nginx 错误消息更花哨，所以我认为它来自 t2d 脚本所做的配置。）
/var/log/nginx/nforem-error.log显示：
2024/02/01 14:09:20 [error] 177919#177919: *1449 connect() failed (111: Unknown error) while connecting to upstream, client: 94.113.160.209, server: evstalkin.com, request: "GET / HTTP/1.1", upstream: "http://172.17.0.5:5000/", host: "evstalkin.com"
并且'docker ps'说：

54678f0806cd postgres:16.1 "docker-entrypoint.s…" 2 days ago Up 2 days 5432/tcp dokku.postgres.foremdb
所以我认为 nginx 无法与 Forem 容器通信，因为它们没有暴露任何端口。
我查看了其他一些东西，但没有发现任何看起来像配置错误的东西。

我如何知道需要配置什么？非常感谢。bhy
答案1
Forem 似乎有一个 docker compose，可以发布端口，我会先运行它
