Swarm：Traefik在撰写服务上返回404

Question

我有两个运行Docker的设备；英特尔NUC和Raspberry Pi。我的NUC用作媒体播放器/媒体服​​务器。这也是管理器节点。该Pi被用作Home Assistant和MQTT机器，并被设置为工作节点。我想将它们添加到群集中，以便可以在两台计算机上将Traefik用于反向代理和HTTPS。

NUC：Traefik，Consul和Portainer的1个docker-compose文件。1个用于我的媒体应用程序的docker-compose文件（Sabnzbd，Transmission-vpn，Sonarr，Radarr等）。

Pi：1个用于家庭助理，MQTT等的docker-compose文件。

Traefik和Portainer已启动并运行。我用docker stack deploy安装它们。接下来，我尝试设置媒体应用程序，但是它们不需要与Pi连接，因此我尝试了“ docker compose”。 Portainer显示应用程序正在运行，但是当我转到其子域Traefik返回未找到404页面时。这使我得出结论，在群体之外运行但连接到Traefik的应用程序不起作用。它们也不会出现在Traefik仪表板中。

我已经尝试了多种操作，例如删除deploy命令，仅使用标签等，但这根本没有帮助。我的Traefik日志也没有显示任何可能说明问题的信息。

您是否正在运行de .env文件来设置环境变量？因为docker stack当前不支持.env功能。您必须在运行docker stack之前手动获取运行export $（cat .env）的.env源。
