Asp.net 为.net核心应用程序创建Dockerfile的问题

我是docker的新手，因此我想寻求帮助为.net核心应用程序创建Dockerfile。 该应用程序具有以下体系结构：

   FarmHouse.Services.AuthenticationService
    │   ├───FarmHouse.Services.AuthenticationService.Api
    │   ├───FarmHouse.Services.AuthenticationService.Logic
    │   └───Dockerfile
    │ 
    ├───FarmHouse.Services.Common
    │   └───FarmHouse.Services.Common.Models
    │   
    └───FarmHouse.Services.EmailService
        ├───FarmHouse.Services.EmailService.Api
        ├───FarmHouse.Services.EmailService.Logic
        └───Dockerfile

这三个项目（

FarmHouse.Services.EmailService

、

FarmHouse.Services.Common

和

FarmHouse.Services.AuthenticationService

）位于同一个解决方案中，

FarmHouse.Services.AuthenticationService

使用

Common

项目中的对象，例如，

FarmHouse.Services.Common

是它的依赖项

我希望其他服务也链接到Common。AuthenticationService的Dockerfile如下所示：

FROM mcr.microsoft.com/dotnet/core/sdk:3.1 AS build-env
WORKDIR /app

# Copy csproj and restore as distinct layers
COPY ./*.sln .
COPY ./FarmHouse.Services.AuthenticationService/FarmHouse.Services.AuthenticationService.Logic/FarmHouse.Services.AuthenticationService.Logic.csproj ./FarmHouse.Services.AuthenticationService.Logic/FarmHouse.Services.AuthenticationService.Logic.csproj
COPY ./FarmHouse.Services.AuthenticationService/FarmHouse.Services.AuthenticationService.Api/FarmHouse.Services.AuthenticationService.Api.csproj ./FarmHouse.Services.AuthenticationService.Api/FarmHouse.Services.AuthenticationService.Api.csproj
COPY ./FarmHouse.Services.Common/FarmHouse.Services.Common.Models/FarmHouse.Services.Common.Models.csproj ./FarmHouse.Services.Common.Models/FarmHouse.Services.Common.Models.csproj

RUN dotnet restore

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

# Build runtime image
FROM mcr.microsoft.com/dotnet/core/aspnet:3.1
WORKDIR /app
COPY --from=build-env /app/out .
ENTRYPOINT ["dotnet", "FarmHouse.Services.AuthenticationService.Api.dll"]

当我从父文件夹运行

docker build

时，我看到以下错误：

>docker build -t coreapp -f ./FarmHouse.Services.AuthenticationService/Dockerfile .

#14 1.643 /usr/share/dotnet/sdk/3.1.406/NuGet.targets(282,5): error MSB3202: The project file "/app/FarmHouse.Services.AuthenticationService/FarmHouse.Services.AuthenticationService.Api/FarmHouse.Services.AuthenticationService.Api.csproj" was not found.

请告知如何在这种情况下修改Dockerfile或架构。

谢谢。

您收到这些错误是因为您在

.sln

文件级别运行

dotnet

命令，因此

dotnet

尝试恢复解决方案中所有未复制的

.csproj

文件

尝试将

dotnet restore

和

publish

命令替换为：

RUN dotnet restore ./FarmHouse.Services.AuthenticationService.Api/FarmHouse.Services.AuthenticationService.Api.csproj

RUN dotnet publish ./FarmHouse.Services.AuthenticationService.Api/FarmHouse.Services.AuthenticationService.Api.csproj -c Release -o out

---

您也可以复制所有

.csproj

文件，只需使用

dotnet restore

即可还原它们，但无论如何，我都会使用

dotnet publish

命令的项目路径。

当我尝试执行此操作时，我收到以下警告：

#17 4.032/usr/share/dotnet/sdk/3.1.406/Microsoft.Common.CurrentVersion.targets（2084,5）：警告MSB3245:无法解析此引用。找不到程序集“FarmHouse.Services.Common.Models”。检查以确保磁盘上存在程序集。如果代码需要此引用，则可能会出现编译错误。[/app/FarmHouse.Services.AuthenticationService.Api/FarmHouse.Services.AuthenticationService.Api.csproj].

然后出现一个错误，指出找不到公共项目中的类型。复制时，您需要复制在

FarmHouse.Services.AuthenticationService.Api.csproj中引用的项目中出现的任何文件夹结构，否则这些相对路径将不起作用。复制公共项目时，您似乎缺少了
FarmHouse.Services.Common
部分。回到问题上来，因为我决定在gitlab中创建管道。在本地，docker build运行良好，但是gitlab没有：
before\u脚本：-apk add--no cache--repositoryhttp://dl-cdn.alpinelinux.org/alpine/edge/community nodejs npm-npm i-g heroku-docker login-u_u-p token registry.heroku.com脚本：-cd FarmHouseServices-docker build-f./FarmHouse.Services.AuthenticationService/Dockerfile。
要创建一个单独的问题，仅使用注释很难理解新问题。
