无法连接到托pipe在Docker容器中的WCF服务

我试图运行一个应用程序，在Docker容器中公开WCF服务。

该应用程序是使用TopShelf构build的，因此它既可以作为Windows服务运行，也可以作为独立的控制台程序（在开发中）运行。

我遇到的问题是WCFtesting客户端无法获取元数据。值得一提的是，应用程序在本地执行时能正常工作。

这是当应用程序在本地运行时由WCFtesting客户端生成的元数据文件

<?xml version="1.0" encoding="utf-8"?> <configuration> <system.serviceModel> <bindings> <netTcpBinding> <binding name="NetTcpBinding_ITestWcfDocker" sendTimeout="00:05:00"> <security mode="None" /> </binding> </netTcpBinding> </bindings> <client> <endpoint address="net.tcp://localhost:9998/" binding="netTcpBinding" bindingConfiguration="NetTcpBinding_ITestWcfDocker" contract="ITestWcfDocker" name="NetTcpBinding_ITestWcfDocker" /> </client> </system.serviceModel> </configuration>

这是我使用构build容器的Dockerfile

 FROM microsoft/dotnet-framework:4.6.2 RUN powershell -Command Add-WindowsFeature NET-WCF-HTTP-Activation45 WORKDIR app COPY bin/Release/net461 . EXPOSE 9998 9999 ENTRYPOINT ["EMG.Service.TestWcfDocker.exe"]

在构build项目之后，我使用此命令构build容器

 docker build -t emg/test-wcf:latest .

然后我用这个命令启动一个容器

 docker run -p 9998:9998 -p 9999:9999 -t emg/test-wcf

这是我在控制台日志上得到的输出

 Configuration Result: [Success] Name EMG.TestWcfDocker, [Success] DisplayName EMG TestWcfDocker, [Success] Description EMG TestWcfDocker, [Success] ServiceName EMG.TestWcfDocker Topshelf v4.0.0.0, .NET Framework v4.0.30319.42000 2017-05-15 15:46:48.0700|DEBUG|WcfServiceHost|Adding NetTcpBinding endpoint for ITestWcfDocker at net.tcp://localhost:9998/ 2017-05-15 15:46:48.1012|DEBUG|WcfServiceHost|Adding Metadata endpoint at http://localhost:9999/ 2017-05-15 15:46:49.2207|INFO|EMG.TestWcfDocker.Program|Starting EMG.TestWcfDocker The EMG.TestWcfDocker service is now running, press Control+C to exit. 2017-05-15 15:46:50.2675|INFO|EMG.TestWcfDocker.Program|EMG.TestWcfDocker started

一旦容器启动，我用它来获取容器的IP

 docker inspect -f="{{range .NetworkSettings.Networks}}{{.IPAddress}}{{end}}" container-name

然后我使用返回的IP通过WCFtesting客户端连接到服务，但我收到此错误消息

如果我使用本地主机，我得到一个类似的错误。

TL;博士：

我有一个Docker容器中的WCF服务，我无法从主机连接到它。
