Support for running in a container?

[thnk2wn]

Is your feature request related to a problem? Please describe. Currently it appears difficult to use raspberryio in a container (or at least not obvious how to).

I see this error

wiringPiSetup: Unable to open /dev/mem or /dev/gpiomem: No such file or directory.
  Aborting your program because if it can not access the GPIO
  hardware then it most certianly won't work
  Try running with sudo?

Currently using .Net Core 3.1 and:

 <PackageReference Include="Unosquare.Raspberry.IO" Version="0.27.0" />
 <PackageReference Include="Unosquare.WiringPi" Version="0.5.0" />

Dockerfille:

# Stage 1
FROM mcr.microsoft.com/dotnet/core/sdk:3.1 AS build
ENV DOTNET_CLI_TELEMETRY_OPTOUT 1
WORKDIR /build
COPY . .
RUN dotnet restore
RUN dotnet publish -c Release -o /app -r linux-arm
# Stage 2
FROM mcr.microsoft.com/dotnet/core/aspnet:3.1.1-buster-slim-arm32v7 AS final
WORKDIR /app
COPY --from=build /app .
ENTRYPOINT ["dotnet", "./siren.dll"]

Project: https://github.com/thnk2wn/rasp-cat-siren/tree/master/siren

Describe the solution you'd like

• Instructions that don't assume deployment is done via dotnet-sshdeploy
• Instructions for any changes to make running in a container both from app level and anything that needs to be setup as a prerequisite

Describe alternatives you've considered I've looked at these threads so far and am still experimenting:

• https://github.com/unosquare/raspberryio/issues/62
• https://raspberrypi.stackexchange.com/questions/40105/access-gpio-pins-without-root-no-access-to-dev-mem-try-running-as-root

Additional context Add any other context or screenshots about the feature request here.
