Question

编辑：我需要将与容器配对的DOCKER虚拟机的端口转发到本地计算机的同一端口。

我试图从使用REST API的docker工具箱容器上本地托管的模型的张量流服务获得响应，并且从我的主机连接到它的任何尝试均收到错误消息。我已经竭尽全力想尝试或寻找解决问题的方法。

我试图同时连接localhost：8501和docker的IP地址192.168.99.101:8501或117.17.0.2:8501容器的IP地址都没有成功。

这里是一张imgur相册，其中包含与我的问题有关的更多详细信息，以提供更多背景信息，包括docker机器详细信息，容器详细信息，我尝试的POST和GET请求，VirtualBox统计信息和容器的日志：{{3 }}

在所有这些尝试中，我还尝试禁用防火墙。

我可以成功ping 192.168.99.101，但不能ping 192.168.99.101:2376或192.168.99.101:8501。

当我进入Docker容器并运行tensorflow_model_server命令时，出现另一个错误，该错误位于imgur画廊的开头。

我的主机操作系统是Windows 10家庭版。

我真的不确定问题是否是网络问题，即虚拟盒子不应该拒绝连接，或者它是否可能是张量流服务方面的问题。

感谢您的任何帮助！

Answer 1

主要是因为您尝试连接的服务器未运行。当我尝试使用mongo创建Flask应用程序时，出现了完全相同的错误。我收到了两次，因为我的mongo服务器未运行，并且我试图连接到它，而下一次，当我试图连接到另一个未运行的服务器时，我得到了它。因此，请检查您的服务器。

如果主机或端口错误，也会发生这种情况。

如果找到其他解决方案，请告知。
