我有一个简单的 ASP.NET Core 2.0 应用程序，解决方案中有 2 个项目。一个项目是一个类库 (WorldLibrary.dll)，它被 Web 应用程序 (WeatherWeb.dll) 引用。

我已尝试按照此处的步骤操作:

https://docs.docker.com/engine/examples/dotnetcore/

这是我的 Dockerfile:

FROM microsoft/aspnetcore-build:2.0 AS build-env
WORKDIR /app

# Copy csproj and restore as distinct layers
COPY *.csproj ./
RUN dotnet restore

# Copy everything else and build
COPY . ./
RUN dotnet publish -c Release -o out

# Build runtime image
FROM microsoft/aspnetcore:2.0
WORKDIR /app
COPY --from=build-env /app/out .
ENTRYPOINT ["dotnet", "WeatherWeb.dll"]

但是，引用的 .dll 存在问题。我从“docker build”命令得到以下输出:

C:\Users\olavt\source\repos\Weather\WeatherWeb>docker build -t weather .

我应该如何正确地将引用的 .dll 正确复制过来？

最佳答案

如果是相关项目，您必须对您的解决方案文件运行 dotnet restore 和 dotnet publish 并将您的 docker 文件放在解决方案级别，以便您可以访问它的所有项目。

基本上，您需要在 docker 文件中进行的唯一更改是:

COPY *.sln ./
COPY ./your_proj1_folder/*.csproj ./your_proj1_folder/
COPY ./your_proj2_folder/*.csproj ./your_proj2_folder/
RUN dotnet restore
