当dockerfile位于项目内的文件夹中且解决方案包括多个项目时运行docker[duplicate]

Question

我向Dot.NET核心应用程序添加了docker支持，这就是我得到的

FROM mcr.microsoft.com/dotnet/aspnet:5.0-buster-slim AS base
WORKDIR /app
EXPOSE 80
EXPOSE 443

FROM mcr.microsoft.com/dotnet/sdk:5.0-buster-slim AS build
WORKDIR /src
COPY ["SMSys.csproj", ""]
COPY ["../DataLayer/DataLayer.csproj", "../DataLayer/"]
COPY ["../Utilities/Utilities.csproj", "../Utilities/"]
COPY ["../ServiceLayer/ServiceLayer.csproj", "../ServiceLayer/"]
RUN dotnet restore "./SMSys.csproj"
COPY . .
WORKDIR "/src/."
RUN dotnet build "SMSys.csproj" -c Release -o /app/build

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

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

我的docker文件在'smsys.csproj'所在的位置。

如果我在该目录中运行docker，我会得到：

COPY failed: forbidden path outside the build context:

如果我在执行copy命令后更改项目的一些引用，并从我所有项目所在的目录外部运行docker，那么我将得到与我的解决方案相关的上千个错误。错误与丢失的东西（程序集和包）有关，好像所有的项目都彼此忽略了，而实际上它们应该彼此很好地引用，就像我通过visual Studio启动项目时所做的那样。

    FROM mcr.microsoft.com/dotnet/aspnet:5.0.3-buster-slim AS base
WORKDIR /app
EXPOSE 80
EXPOSE 443

 
FROM mcr.microsoft.com/dotnet/sdk:5.0.103-buster-slim AS build 
WORKDIR /src

RUN dotnet restore "./SMSysSolution/SMSys.csproj"
COPY . .
WORKDIR "/src/SMSysSolution"
RUN dotnet build "SMSys.csproj" -c Release -o /app/build

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

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

我必须对路径做一些改动才能使它正常工作。

DockerFile

请注意您的复制说明。第一个位置是您的物理位置，而另一个是容器内的位置。显然，您正在尝试创建这样的树：

| src
  | SMSys.csproj
| DataLayer
  | ...
| Utilities
  | ...
| ...

我不确定这是不是你想要的...

FROM mcr.microsoft.com/dotnet/aspnet:5.0.3-buster-slim AS base
WORKDIR /app
EXPOSE 80
EXPOSE 443

FROM mcr.microsoft.com/dotnet/sdk:5.0.103-buster-slim AS build
WORKDIR /src
COPY ["{FOLDER OF THE SMSys.csproj}/SMSys.csproj", "{MATCHING FOLDER OF THE SMSys.csproj}/"]
COPY ["DataLayer/DataLayer.csproj", "DataLayer/"]
COPY ["Utilities/Utilities.csproj", "Utilities/"]
COPY ["ServiceLayer/ServiceLayer.csproj", "ServiceLayer/"]
RUN dotnet restore "./SMSys.csproj"
COPY . .
WORKDIR "/src/{FOLDER OF THE SMSys.csproj}"
RUN dotnet build "SMSys.csproj" -c Release -o /app/build

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

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

| src
  | {FOLDER OF THE SMSys.csproj}
    | SMSys.csproj
  | DataLayer
    | ...
  | Utilities
    | ...
  | ...

| docker-compose.yaml
| {FOLDER OF THE SMSys.csproj}
| DataLayer
| Utilities
| ...

然后，在文件内部：

services:
    smsys-app:
        ports:
           - "..." # ports of the services
        build:
            context: .
            dockerfile: {FOLDER OF THE SMSys.csproj}/Dockerfile

这是假设您将DockerFile保持在smsys.csproj的同一级别，但您可以将其放在另一个位置：）
