So I have simple hello world .net core application setup on my local machine running on docker container using docker-compose
The problem is when I tried to attach debugger from vs2019 using Debug -> Attach to Process -> ConnectionType Docker(Linux Container) -> select the process and hit attach.
I got error stated
Failed to launch debug adapter 'coreclr'.
Failed to copy files.
Initialization log:
Determining user folder on remote system...
Checking for existing installation of debugging tools...
Downloading debugger launcher...
Creating debugger installation folder: /root/.vs-debugger
Copying debugger launcher to /root/.vs-debugger/GetVsDbg.sh
Failed: Failed to copy files.
The program '[360] bash' has exited with code -1 (0xffffffff).
It seems for some reason the visual studio tried to copy the debugger to the running container but failed
here's the simple dockerfile and docker-compose script
Dockerfile
FROM microsoft/aspnetcore-build:1.1.2
RUN apt-get update && apt-get install -y unzip
RUN curl -sSL \
https://aka.ms/getvsdbgsh | bash /dev/stdin -v vs2019 -l /root/.vs-debugger
COPY node_modules/wait-for-it.sh/bin/wait-for-it /tools/wait-for-it.sh
RUN chmod +x /tools/wait-for-it.sh

VOLUME /app
WORKDIR /app
ENTRYPOINT dotnet restore \

Note: - I have already tick the Shared Drive on the docker host
any clue about this?
It seems for some reason visual studio didn't have access to the docker-users group in spite I already add my current user account to the group
The workaround is to create new windows user and add it to the docker-users group. It works like a charm
