Question

我正在尝试制作运行ASP.NET Core应用程序的Windows Nano Server容器我正在Windows Server 2016上构建它。我可以使它工作，但有一个奇怪的问题。

我能使其工作的唯一方法是构建映像，运行容器，然后启动交互式Powershell会话并使用Invoke-WebRequest http://localhost:5000。一旦我从内部容器中执行此操作，就可以从其他服务器看到该应用程序（由于已知的NAT错误，我无法从Win2016服务器本地浏览容器。）

这是我的Dockerfile：

FROM microsoft/dotnet:sdk-nanoserver
ARG source
WORKDIR /app
COPY /ContainerPOC/ .
RUN dotnet restore --runtime win10-x64 .

RUN dotnet build --framework netcoreapp1.1 --runtime win10-x64 .

EXPOSE 5000
ENV ASPNETCORE_URLS http://0.0.0.0:5000
CMD dotnet run --framework netcoreapp1.1

知道为什么这不会“正常工作”？

这对我有用：

λ  cat .\Dockerfile
FROM microsoft/dotnet:2.0.0-preview1-sdk-nanoserver

WORKDIR /app
RUN dotnet new mvc
RUN dotnet restore
RUN dotnet build
ENV ASPNETCORE_URLS http://0.0.0.0:5000
CMD dotnet run

C:\code\repros\dotnet-sample
λ  docker build -t test .
