Provide docker images for Linux host systems

[heavyrubberslave]

The server can actually run inside a docker container on Linux operating systems:

Dockerfile

FROM node:22-bullseye-slim

RUN apt-get update && apt-get install -y wget udev build-essential

WORKDIR app/
VOLUME /root/.slvctrlplus

RUN wget https://github.com/SlvCtrlPlus/slvctrlplus-server/releases/latest/download/dist.tar.gz -O - | tar -xz

# Set default environment variables
ENV PORT=1337
ENV LOG_LEVEL=debug

# Expose port 1337
EXPOSE 1337

# Start the Node app
CMD ["node", "/app/dist/index.js"]

docker-compose.yaml

services:
  slvctrlplus-server:
    build: .
    container_name: slvctrlplus-server
    privileged: true # that's the important bit
    ports:
      - "1337:1337"
    volumes:
      - /dev:/dev
      - /sys:/sys:ro
      - /run/udev:/run/udev:ro
      - ./config:/root/.slvctrlplus
