由於相對路徑，在 Docker 容器中運行 dotnet 在 Linux 上失敗

Question

我有一個 Dockerfile 構建應用程序並將其發布到這樣的容器

FROM mcr.microsoft.com/dotnet/sdk:5.0 as builder
COPY . ./
RUN dotnet publish Project -c Release -o ./publish

FROM mcr.microsoft.com/dotnet/runtime:5.0 as runner
COPY --from=builder  /publish .
WORKDIR data
ENTRYPOINT ["dotnet", "../Project.dll"]

構建映像和運行容器在 Windows 上有效，但在 Ubuntu 服務器上無效。

project_1  | Unhandled exception. System.IO.FileNotFoundException: Could not load file or assembly '/Project.dll'. The system cannot find the file specified.
project_1  |
project_1  | File name: '/Project.dll'

I think the problem is in specifying the argument for dotnet as ../Project.dll , because the shell expands this to /Project.dll and dotnet does not understand Linux paths. 有沒有辦法來解決這個問題？

我是 Docker 的初學者，也許我遺漏了一些東西（Docker 不應該在每個平台上都一樣嗎？）

編輯：在父目錄內的容器中從 bash 運行dotnet Project.dll會產生完全相同的 output

原來是權限問題，應用程序必須在子文件夾（不是根文件夾），見https://docs.docker.com/engine/examples/dotnetcore/

FROM mcr.microsoft.com/dotnet/sdk:5.0 as builder
WORKDIR /app
COPY . ./
RUN dotnet publish Project -c Release -o ./publish

FROM mcr.microsoft.com/dotnet/runtime:5.0 as runner
WORKDIR /app
COPY --from=builder  /app/publish .
WORKDIR /app/data
CMD ../Project
