Question

我正在尝试通过Traefik反向代理和SSL终端将后端（python，端口9000）连接到外部。这是我第一次Traefik体验，因此在3个小时的文档阅读和配置后，我仍然可能会错过一些东西，而我对docker也很陌生。

我怀疑网络有问题。

到目前为止，该Swarm仅限于一个节点。这是设置。 Redis由后端使用，这基本上可以工作。问题是我无法通过Traefik到达后端。它只是不断加载并最终超时。

private IEnumerable<int> GetIdsByCommandLine(string commandLine)
{
    using (ManagementObjectSearcher searcher = new ManagementObjectSearcher("SELECT ProcessID FROM Win32_Process WHERE CommandLine = " + commandLine))
    using (ManagementObjectCollection objects = searcher.Get())
    {
        foreach (var element in objects)                
            yield return (int) element["ProcessId"];                
    }
}

我在Traefik的日志输出中发现的东西

后端获得内部IP，这些IP当然是无法公开访问的，但是我认为这应该由Traefik处理并转发到外部“ Webgateway”网络。

此外，我对Traefik感到困惑，抱怨缺少Redis的端口标签，我使用api将其放置在自己的网络中以摆脱此困扰，但Traefik仍然对此表示抱怨。它还抱怨自己的服务。

...    | time="2018-09-12T14:01:18Z" level=debug msg="No virtual IPs found in network 3npv6h0g3vjv2agnj3moqcz7m"
...    | time="2018-09-12T14:01:18Z" level=debug msg="No IP addresses found for network 3npv6h0g3vjv2agnj3moqcz7m"

在此先感谢您的帮助。
