permission issue on vsdbg while running docker.exe - exec: \"/app/vsdbg\: permission denied

问题

My object is to debug the docker container using vsdbg , this container contains asp.net core api application. To do this, created docker image using docker file, and then run the container. And to start remote debugging , used below command:

docker exec -i  a05a0439540b  "/app/vsdbg"

then got below error message:

OCI runtime exec failed: exec failed: container_linux.go:344: starting    
container process caused "exec: \"/app/vsdbg\": permission denied": unknown

please find below docker file content:

FROM mcr.microsoft.com/dotnet/core/aspnet:2.2-stretch-slim AS base
WORKDIR /app
EXPOSE 80
#EXPOSE 443

WORKDIR "/src/"
RUN dotnet build "testDockerCore.csproj" -c Release -o /app

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

FROM base AS final
WORKDIR /app
COPY --from=publish /app .
ENTRYPOINT ["dotnet", "testDockerCore.dll"]

but still facing same error.

using below command to start docker image:

docker run -it -p 4200:4024 testdockercore:dev

can you please help me out to resolve this problem.

回答1:

I ran into this same issue today - the error message is a little confusing. There are no execute permissions on the /vsdbg directory; instead of "/app/vsdbg" you're launch.json needs to read:

"debuggerPath": "/app/vsdbg/vsdbg",

Have the same issue running chmod 777 -R /root/vsdbg/vsdbg for me the vsdbg is under root folder
