将 Traefik 与 Nginx 一起使用时出现 404 错误答案

【问题标题】：404 Error When Using Traefik With Nginx将 Traefik 与 Nginx 一起使用时出现 404 错误
【发布时间】：2018-08-29 18:45:04
【问题描述】：

我的设置是通过 Rancher/Docker，我正在尝试通过使用 Traefik 使我的 InvoiceNinja 堆栈在线。

我目前有另外两个可以公开的容器，但之前不必尝试通过 nginx 容器进行连接。

访问https://invoiceninja.example.com 时，我只是收到 404 错误。我可以使用主机和容器的 IP 和端口在本地访问它。

        location ~ /\.ht {

    }
}

我尝试（并且仍然）使用“traefik.frontend.passHostHeader: true”标签作为类似问题，但似乎没有什么不同。

非常感谢任何帮助！谢谢！

我不久前又回到了这个问题，所以我可能不完全记得所有问题是什么。

据我所知：

容器命名不一致，使用了错误的主机名。
在 docker-compose.yml 文件中使用环境变量会导致一些问题，以后无法更改它们。删除容器时，我经常没有完全删除持久数据卷，这也导致了问题，之前设置的环境变量，并且在新部署中不容易更改。
