如何在没有Visual Studio且没有docker compose的情况下使用docker复制csproj文件？ [英] How to copy a csproj file using docker without visual studio and without docker compose?

问题描述

我刚刚使用Visual Studio 15.8.8通过.NET Core项目（2.1）开始了新的解决方案。通过将docker compose文件设置为启动项目，它可以运行和调试它。

I just started a new solution with a .NET Core Project (2.1) using visual studio 15.8.8. It can run and debug it by setting the docker compose file as a startup project. It works!

从逻辑上讲，我应该能够使用简单的命令行语句来构建docker镜像。但是，它抱怨找不到csproj。这很奇怪。该文件存在，并且正如我所告诉的，我可以从Visual Studio中运行它。我从一个目录和具有dockerfile的目录尝试了它。同样的问题。

Logically, I should be able to build the docker image with a simple commandline statement. However, it complains that the csproj cannot be found. This is strange. The file exist and as I told, I can run it from visual studio. I tried it from one directory up and the directory that has the dockerfile. Same problem.

我该如何解决？我唯一想要的就是简单地构建映像，然后仅使用docker命令运行它。

How can I solve this? The only thing I want is simply build my image and then run it by just using docker commands.

Dockerfile

Dockerfile

FROM microsoft/dotnet:2.1-aspnetcore-runtime AS base
WORKDIR /app
EXPOSE 80

FROM microsoft/dotnet:2.1-sdk AS build
WORKDIR /src
COPY ["TryNewDocker2/TryNewDocker2.csproj", "TryNewDocker2/"]
RUN dotnet restore "TryNewDocker2/TryNewDocker2.csproj"
COPY . .
WORKDIR "/src/TryNewDocker2"
RUN dotnet build "TryNewDocker2.csproj" -c Release -o /app

FROM build AS publish
RUN dotnet publish "TryNewDocker2.csproj" -c Release -o /app

FROM base AS final
WORKDIR /app
COPY --from=publish /app .
ENTRYPOINT ["dotnet", "TryNewDocker2.dll"]

Het是撰写文件：

version: '3.4'

services:
  trynewdocker2:
    image: ${DOCKER_REGISTRY}trynewdocker2
    build:
      context: .
      dockerfile: TryNewDocker2/Dockerfile

从逻辑上讲，我希望 docker-compose up保持不变

Logically, I want "docker-compose up" to keep working when fixing this problem.

推荐答案

这是由dockerfile中文件路径的错误根文件夹引起的。

This is caused by the wrong root folder for the file path in dockerfile.

要从 Docker 启动，其根文件夹为 C：\Users\ ... \repos\TryNewDocker2 ，但是从命令运行时，其根目录为 C：\用户-... \repos\TryNewDocker2\TryNewDocker2 ，因此 TryNewDocker2.csproj 的路径已从 TryNewDocker2 / TryNewDocker2.csproj 到 TryNewDocker2.csproj

For launching from Docker, its root folder is C:\Users\...\repos\TryNewDocker2, but while running from command, its root fodler is C:\Users\...\repos\TryNewDocker2\TryNewDocker2, so the path for TryNewDocker2.csproj has changed from TryNewDocker2/TryNewDocker2.csproj to TryNewDocker2.csproj

尝试以下dockerfile：

Try dockerfile below:

FROM microsoft/dotnet:2.1-aspnetcore-runtime AS base
WORKDIR /app
EXPOSE 59162
EXPOSE 44342

FROM microsoft/dotnet:2.1-sdk AS build
WORKDIR /src
COPY ["TryNewDocker2.csproj", "TryNewDocker2/"]
RUN dotnet restore "TryNewDocker2/TryNewDocker2.csproj"
COPY . ./TryNewDocker2/
WORKDIR "/src/TryNewDocker2"
RUN dotnet build "TryNewDocker2.csproj" -c Release -o /app

FROM build AS publish
RUN dotnet publish "TryNewDocker2.csproj" -c Release -o /app

FROM base AS final
WORKDIR /app
COPY --from=publish /app .
ENTRYPOINT ["dotnet", "TryNewDocker2.dll"]

更新

要在Docker和命令中都可以使用，请不要更改dockerfile，请从下面的路径通过指定dockerfile路径运行命令。

For working in both Docker and command, do not change your dockerfile, and from path below to run your command with specifying the dockerfile path.

C:\Users\...\repos\TryNewDocker2>docker build -t gogo -f TryNewDocker2/Dockerfile .
