Docker 文件 - 跳过项目。因为没找到

Question

我在一个解决方案中有 3 个项目。

[解决方案]'BuySellApi'（3个项目）
  | 
  +-- [BuySellApi]
  | |
  | +--- BuySellApi.csproj（该项目包含Docker文件）
  |
  +-- [BuySellApi.Core]
  | |
  | +--- BuySellApi.Core.csproj
  |
  +-- [BuySellApi.Data]
       |
       +--- BuySellApi.Data.csproj

 1. BuySellApi.csproj -> API
 2. BuySellApi.Data/BuySellApi.Data.csproj -> 模型
 3. BuySellApi.Core/BuySellApi.Core.csproj -> 数据访问

我正在尝试通过在Dockerfile 中指定以下命令来使用 Docker 构建它

FROM microsoft/dotnet:2.2-aspnetcore-runtime AS base
WORKDIR /app
EXPOSE 5000
ENV ASPNETCORE_URLS=http://+:5000

FROM microsoft/dotnet:2.2-sdk AS build
WORKDIR /src
COPY ["BuySellApi.csproj", "./"]
COPY ["BuySellApi.Data/BuySellApi.Data.csproj", "./"]
COPY ["BuySellApi.Core/BuySellApi.Core.csproj", "./"]
RUN dotnet restore "./BuySellApi.csproj"
COPY . .
WORKDIR "/src/."
RUN dotnet build "BuySellApi.csproj" -c Release -o /app

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

FROM base AS final
WORKDIR /app
COPY --from=publish /app .
ENTRYPOINT ["dotnet", "BuySellApi.dll", "--server.urls", "http://0.0.0.0:5000"]

运行以下命令后

docker build -t cog/buysellapi .

我收到如下错误：

e:\Apps\trunk\BuySell\BuySellApi>docker build -t cog/buysellapi .
Sending build context to Docker daemon  19.15MB

COPY failed: stat /mnt/sda1/var/lib/docker/tmp/docker-builder475321395/BuySellApi.Data/BuySellApi.Data.csproj: no such file or directory

它不是复制数据和核心层。当我为单个项目的解决方案尝试同样的事情时，它工作正常。

Answer 1

就我而言，找不到项目文件，因为我正在构建Linux容器，并且出于某种原因，项目文件名及其路径的字母大小写与文件系统中的字母大小写不同。

Answer 2

根据您的输入，我建议以下文件夹结构和 Dockerfile。
