我想對現有的 .NET core 5 應用程式進行 dockerize，并使用容器工具生成 Dockerfile。當我使用 Visual Studio 2022 進行除錯時，它可以作業，但是當我使用命令手動運行它時，docker build -t some-name .它會生成以下錯誤：
Step 7/21 : COPY ["MechEng.MovableBridges.Api/MechEng.MovableBridges.Api.csproj", "MechEng.MovableBridges.Api/"]
COPY failed: file not found in build context or excluded by .dockerignore: stat MechEng.MovableBridges.Api/MechEng.MovableBridges.Api.csproj: file does not exist
為什么找不到檔案？
這是我在MechEng.MovableBridges.Api檔案夾內的 Dockerfile ：
#See https://aka.ms/containerfastmode to understand how Visual Studio uses this Dockerfile to build your images for faster debugging.

uj5u.com熱心網友回復：
您的命令失敗，因為構建背景關系錯誤。Visual Studio 使用解決方案根檔案夾作為構建背景關系，您（可能）正在使用專案的 dockerfile 位置。您可以在此處閱讀有關 docker build 命令的更多資訊。
您的命令應該類似于：
docker build -f "<path-to-your-dockerfile>" -t some-name "<!!!path-to-your-solution-folder!!!>"
您可以在輸出視窗中看到 Visual Studio 執行的確切命令，從下拉框中選擇“容器工具”。
