Getting Docker Dev Engine to work with VS Code

whenever I run the dev engine, I get the following error at the end of the install:

chown: invalid group: ‘root:docker’
WARNING: Could not change owner for docker socket in container : exit code 1
Docker socket permission set to allow in container docker

I am on macOS, so not sure if I need to create a docker group or not.

I have the following Dockerfile.devenv

FROM python:3.9-buster
COPY requirements.txt requirements.txt
COPY . .
RUN pip install -r requirements.txt
USER root
WORKDIR /src
EXPOSE 8000
RUN useradd -ms /bin/bash devenv

and no docker compose file.

    According to the documentation: https://learn.microsoft.com/en-us/visualstudio/mac/docker-quickstart?view=vsmac-2019

    It could be possible to run the service of Visual Studio by configurating the dockerfile:

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

FROM mcr.microsoft.com/dotnet/core/sdk:2.2-stretch AS build
WORKDIR /src
COPY DockerDemo/DockerDemo.csproj DockerDemo/
RUN dotnet restore "DockerDemo/DockerDemo.csproj"
COPY . .
WORKDIR "/src/DockerDemo"
RUN dotnet build "DockerDemo.csproj" -c Release -o /app/build

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

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

    So it could be possible to run your python environment within the environment for visual studio to run over macOS:

    FROM python:3.9-buster
COPY requirements.txt requirements.txt
COPY . .
RUN pip install -r requirements.txt
USER root
WORKDIR /src
EXPOSE 8000
RUN useradd -ms /bin/bash devenv

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

FROM mcr.microsoft.com/dotnet/core/sdk:2.2-stretch AS build
WORKDIR /src
COPY DockerDemo/DockerDemo.csproj DockerDemo/
RUN dotnet restore "DockerDemo/DockerDemo.csproj"
COPY . .
WORKDIR "/src/DockerDemo"
RUN dotnet build "DockerDemo.csproj" -c Release -o /app/build

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

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

    Based on docker documentation when we are specifying Dockerfile, we need to make sure that we are using vscode user and included to docker group.

    So i think your Dockerfile.devenv need to be updated. e.g:

    FROM python:3.9-buster

WORKDIR /src
COPY requirements.txt requirements.txt
COPY . .
RUN pip install -r requirements.txt

# create vscode user then add to docker group
RUN useradd -s /bin/bash -m vscode 
 && groupadd docker 
 && usermod -aG docker vscode

USER vscode

EXPOSE 8000
