C# 如何为多个项目构建一个docker映像？

在我的项目中，我使用.NETCore2.2，最近我在项目中使用了额外的类库。 当我试图建立我的形象，它无法找到我的dll

我的docker文件如下所示：

FROM mcr.microsoft.com/dotnet/core/sdk:2.2 AS build-env
WORKDIR /app
# Copy csproj and restore as distinct layers
COPY *.csproj ./
RUN dotnet restore

COPY . ./
RUN dotnet publish -c Release -o out
# Build runtime image
FROM mcr.microsoft.com/dotnet/core/aspnet:2.2
WORKDIR /app
EXPOSE 80
COPY --from=build-env /app/out .
ENTRYPOINT ["dotnet", "LibvirtManagement.dll"]

我得到的错误如下：

 The project file "/JenkinsService/JenkinsService.csproj" was not found. 
 [/app/LibvirtManagement.sln]
The command '/bin/sh -c dotnet publish -c Release -o out' returned a non-zero code: 1

错误消息非常简单，您在构建该项目的docker容器中缺少了该项目的

JenkinsService.csproj

和其他文件。您还需要复制这些文件

如果您使用的是Visual Studio，最简单的方法是右键单击可执行项目文件（

LibvirtManagement

），然后选择

Add->Docker Support…

。它将自动为您生成正确的

Dockerfile

编辑：这是该工具为我创建的内容：

#See https://aka.ms/containerfastmode to understand how Visual Studio uses this Dockerfile to build your images for faster debugging.

FROM mcr.microsoft.com/dotnet/core/aspnet:2.2-stretch-slim AS base
WORKDIR /app
EXPOSE 80
EXPOSE 443

FROM mcr.microsoft.com/dotnet/core/sdk:2.2-stretch AS build
WORKDIR /src
COPY ["LibvirtManagement/LibvirtManagement.csproj", "LibvirtManagement/"]
COPY ["JenkinsService/JenkinsService.csproj", "JenkinsService/"]
RUN dotnet restore "LibvirtManagement/LibvirtManagement.csproj"
COPY . .
WORKDIR "/src/LibvirtManagement"
RUN dotnet build "LibvirtManagement.csproj" -c Release -o /app/build

FROM build AS publish
RUN dotnet publish "LibvirtManagement.csproj" -c Release -o /app/publish

FROM base AS final
WORKDIR /app
COPY --from=publish /app/publish .
ENTRYPOINT ["dotnet", "LibvirtManagement.dll"]

我得到了这个错误

COPY[“LibvirtManagement/LibvirtManagement.csproj”，“LibvirtManagement/”]复制失败：stat/var/lib/docker/tmp/docker-builder036005313/LibvirtManagement/LibvirtManagement.csproj:在我的项目中没有这样的文件或目录，在我的情况下，我不知道这是否有意义。因为我不想在这里发布代码
