具有多个 cs 项目引用的 dotnetcore2.0 的 DockerFile

Question

我是运行一个 .netcore2.0 webapi，使用 Visual studio 2017 for MAC。我的项目结构如下。

src
    --Solution.sln
    -- Common
        -- commonPrj
            -- Common.csproj
    --Data
        --  QM
            --  QM.csproj
        --Repo
            --Repo.csproj
    --Ser
        --  Host
            -- Api
                --api.csproj

我也有 DOCKERFILE 内容。在执行 dotnet 构建过程时抛出错误，因为构建代理无法解析 common.csproj/ 我认为我的 docker 文件定义是错误的。有人可以协助完成这项工作[我在这里尝试了很多选项 dockerfile]>?

#FROM microsoft/aspnetcore-build:2.0 AS build-env
FROM microsoft/aspnetcore

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

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

# build runtime image
#FROM microsoft/aspnetcore:2.0
#WORKDIR /app
#COPY --from=build-env /app/out .

#EXPOSE 5000

COPY ./out /out
WORKDIR /out
#WORKDIR /publish


ENTRYPOINT ["dotnet", "Rando.MortgageCenter.WebAPI.dll"]

我正在尝试使用 Docker 云环境 [cloud.docker.com/swarm]

Answer 1

所以我发现您必须将 DOCKERFILE 放在 src 文件夹中，该文件夹是解决方案的根目录。这样 docker 上下文就变成了这个路径。

现在你有一个 Dockerfile 如下

FROM microsoft/aspnetcore-build:2.0 as build
WORKDIR /app


COPY . . 

#COPY Solution.sln .
# RUN ls -l
RUN dotnet restore ./Solution.sln

COPY . .

RUN dotnet publish ./Ser/Host/Api/api.csproj --output /out/ --configuration Release

# runtime image
FROM microsoft/aspnetcore:2.0
WORKDIR /app
COPY --from=build /out .

ENTRYPOINT ["api.dll"]

希望这对遇到我所面临问题的人有所帮助
