Docker with Windows container support wcf on tcp services

I have a simple test wcf service with net.tcp binding with this config :

<system.serviceModel>
<services>
  <service name="WcfServiceWebApp.Service1">
    <endpoint binding="basicHttpBinding" contract="WcfServiceWebApp.IService1" />
    <endpoint address="" binding="netTcpBinding" contract="WcfServiceWebApp.IService1" bindingConfiguration="noSecurityBind"/>
    <endpoint address="mex" binding="mexHttpBinding" contract="IMetadataExchange" />
    <host>
      <baseAddresses>
        <add baseAddress="net.tcp://localhost:83/Service1.svc" />
      </baseAddresses>
    </host>
  </service>
</services>
<bindings>
  <netTcpBinding>
    <binding name="noSecurityBind" portSharingEnabled="false">
      <security mode="None" />
    </binding>
  </netTcpBinding>
</bindings>
<behaviors>
  <serviceBehaviors>
    <behavior>
      <!-- To avoid disclosing metadata information, set the values below to false before deployment -->
      <serviceMetadata httpGetEnabled="true" httpsGetEnabled="true"/>
      <!-- To receive exception details in faults for debugging purposes, set the value below to true.  Set to false before deployment to avoid disclosing exception information -->
      <serviceDebug includeExceptionDetailInFaults="false"/>
    </behavior>
  </serviceBehaviors>
</behaviors>
<protocolMapping>
    <add binding="basicHttpsBinding" scheme="https" />
</protocolMapping>    
<serviceHostingEnvironment aspNetCompatibilityEnabled="true" multipleSiteBindingsEnabled="true" />

I build a docker image based on windows/wcf image with this dockerfile :

    FROM microsoft/wcf:4.7.1
# Next, this Dockerfile creates a directory for your application
RUN mkdir C:\WcfServiceTest
# configure the new site in IIS.
RUN powershell -NoProfile -Command \
Import-module IISAdministration; \
New-IISSite -Name "WcfServiceTest" -PhysicalPath C:\WcfServiceTest -BindingInformation "*:83:"

RUN Import-Module WebAdministration; Set-ItemProperty "IIS:\\Sites\\WcfServiceTest" -name bindings -value (@{protocol='net.tcp';bindingInformation='808:*'},@{protocol='http';bindingInformation='*:83:'});
# This instruction tells the container to listen on port 83.
EXPOSE 83

COPY . C:\\WcfServiceTest

Docker build command : 

docker build -t axesnetbws.image .

I then run the container with the command : 

 docker run -d -p 83:83 --name testcontainer mytestimage

After that I get the IP address of the container with :

docker inspect --format="{{.NetworkSettings.Networks.nat.IPAddress}}" testcontainer

Then I get on my web browser (Chrome) and enter the address http://<uri_from_docker_inspect>:83/Service1.svc?wsdl

I get an error :

Could not find a base address that matches scheme net.tcp for the endpoint with binding NetTcpBinding. Registered base address schemes are [http].
Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code. 

Exception Details: System.InvalidOperationException: Could not find a base address that matches scheme net.tcp for the endpoint with binding NetTcpBinding. Registered base address schemes are [http].

What's weird is that if I just copy the site in Default Web Site (COPY . /inetpub/wwwroot/) and call http://<uri_from_docker_inspect_NO_PORT>/Service1.svc?wsdl IT WORKS ! So what would be the problem when using a new website or application ?

I finally got it working by transforming the site to a web application. Just added this line before EXPOSE 83 :

RUN windows\system32\inetsrv\appcmd.exe set app 'WcfServiceTest/' /enabledProtocols:"http,net.tcp"

So the final dockerfile is :

FROM microsoft/wcf:4.7.1
ARG source
# Next, this Dockerfile creates a directory for your application
RUN mkdir C:\WcfServiceTest
# configure the new site in IIS.
RUN powershell -NoProfile -Command \
Import-module IISAdministration; \
New-IISSite -Name "WcfServiceTest" -PhysicalPath C:\WcfServiceTest-BindingInformation "*:83:"

RUN Import-Module WebAdministration; Set-ItemProperty "IIS:\\Sites\\WcfServiceTest" -name bindings -value (@{protocol='net.tcp';bindingInformation='808:*'},@{protocol='http';bindingInformation='*:83:'});
RUN windows\system32\inetsrv\appcmd.exe set app 'WcfServiceTest/' /enabledProtocols:"http,net.tcp"
# This instruction tells the container to listen on port 83.
EXPOSE 83

COPY ${source:-obj/Docker/publish} c:\\WcfServiceTest
