我正在尝试调试一个Linux容器，该容器运行Visual Studio 2019(版本16.11.10(中的C#/.NET 6.0控制台应用程序。
当我使用调试/附加到进程时。。。为了连接到我正在运行的容器并连接到我的进程，我得到了错误：
无法启动调试适配器。输出窗口中可能提供其他信息。
在"/home/dokeruser/.vs debugger"中找不到调试器脚本
出于公司安全目的，我以用户dockeruser的身份运行容器工作负载，但当我将Dockerfile调整为以root用户身份运行时，我可以重现这种情况。错误消息变为
无法在"/root/.vs debugger"中找到调试器脚本
输出显示
Unable to find debugger script at '/home/dockeruser/.vs-debugger'.
Initialization log:
Determining user folder on remote system...
Checking for existing installation of debugging tools...
Downloading debugger launcher...
Creating debugger installation folder: /home/dockeruser/.vs-debugger
Copying debugger launcher to /home/dockeruser/.vs-debugger/GetVsDbg.sh
Failed: Failed to copy files.
Unable to find debugger script at '/home/dockeruser/.vs-debugger'.
Failed: Unable to find debugger script at '/home/dockeruser/.vs-debugger'.
The program '[1] dotnet' has exited with code -1 (0xffffffff).
我可以通过docker exec在我的容器上运行bash会话并运行GetDbgVs.sh来解决这个问题，如中所述https://stackoverflow.com/a/68950674/17273131，但这样做很痛苦——感觉有些事情被误解了。
我已经验证了我的windows身份是windowsdocker-users组的成员。
虽然不是我想要的答案，但我有一个1行shell解决方案，当我想用VS2019调试附加时，我会在容器上执行，一旦我知道我的<CONTAINER_NAME>。这可能对其他有此问题的人有用。
docker exec -u root <CONTAINER_NAME> sh -c "apt-get update && apt-get install wget -y"; docker exec <CONTAINER_NAME> sh -c "mkdir -p ~/.vs-debugger; wget https://aka.ms/getvsdbgsh -O ~/.vs-debugger/GetVsDbg.sh; chmod a+x ~/.vs-debugger/GetVsDbg.sh"
- 第一个命令将wget安装为root
- 第二个命令将GetVsDbg.sh下载到~/.vs调试器
在我的情况下，我没有GetVsDbg.sh。我只是把它从我的旧机器上复制下来，放在~/.vs-debugger/GetVsDbg.sh下，它就工作了。GetVsDbg.sh的内容是：
