我正在尝试创建一个API微服务，它利用了一个共享的模型库。在创建镜像时，我需要在范围内包含这些类。然而，由于我的项目结构，这些模型并不总是在范围内。我决定使用这些通用模型创建一个基础镜像，并在这些镜像之上构建我的API。然而，我遇到了一个问题，我认为是一个结构问题，我只是似乎不能 Package 我的头周围。
当构建时，我收到下面提到的错误。如果我手动引用这些库的位置，我通常没有问题，但是我需要它们在一个可重用的映像中，以便于使用。
下面是两个dockerfile，以及我的项目是如何结构化的示例，以及构建时API期望从哪里导入类库。你知道我做错了什么吗？

API dockerfile

FROM base-image AS base
    WORKDIR /App
    EXPOSE 80
    
    FROM mcr.microsoft.com/dotnet/sdk:6.0-focal AS build
    WORKDIR /src
    
    
    COPY ["Audit.API/Audit.API.csproj", "Services/Audit/Audit.API/"]
    COPY --from=base /src/EventBus.Messages/ /src/Building-Blocks/EventBus.Messages/
    
    RUN dotnet restore "./Services/Audit/Audit.API/Audit.API.csproj" --source http://address
    COPY . .
    WORKDIR "/src/Services/Audit/Audit.API"
    RUN dotnet build "Audit.API.csproj" -c Release -o /App/build
    
    FROM build AS publish
    RUN dotnet publish "Audit.API.csproj" -c Release -o /App/publish /p:UseAppHost=false
    
    FROM base AS final
    WORKDIR /App
    COPY --from=publish /App/publish .
    ENTRYPOINT ["dotnet", "Audit.API.dll"]

基础Dockerfile

WORKDIR /src
COPY ["Responses/Responses/Responses.csproj", "Responses/"]
COPY ["EventBus.Messages/EventBus.Messages.csproj", "EventBus.Messages/"]

你忘了把源代码复制到基础映像上。

FROM mcr.microsoft.com/dotnet/sdk:6.0-focal AS build
WORKDIR /src
COPY ["Responses/Responses/", "Responses/"]
COPY ["EventBus.Messages/", "EventBus.Messages/"]

我认为构建单个映像的问题是由于启动docker build命令的位置。
您可以从根文件夹开始执行docker build，并使用-f参数指定Dockerfile，在本例中，是您在Dockerfile上设置的指向根文件夹的路径。
您可以保存Dockerfile的任何路径，重要的是要记住，Dockefile中的路径是指您启动build命令的路径，或者您如何更改/指定命令的路径，通常是点（docker build -t xxx -f Dockerfile .）最后一个点是Dockerfile上引用的文件夹。
根路径上的Dockerfile。
积木
--EventBus.Messages
服务项目
--审计
----Audit.API
Dockerfile

将这些条目添加到.dockerignore文件中

**/bin
**/obj
**/.vscode
**/.vs

否则使用--no-restore的构建会失败，因为在COPY阶段，如果您在windows上开发并在linux映像上构建，它还复制了（可能）不同程序集的bin&obj文件夹。
然后，您可以从root docker build -t whatever -f Dockerfile .运行build命令
