cupsd in a docker container.

Based on debian:bullseye-slim. Includes cupsd along with every printer driver I could think of.

Admin user & passwords default to print / print

Run the server

Start cupsd with:

sudo docker run -d --restart unless-stopped \
  -p 631:631 \
  --privileged \
  -v /var/run/dbus:/var/run/dbus \
  -v /dev/bus/usb:/dev/bus/usb \
  -v $(pwd)/printers.conf:/etc/cups/printers.conf \
  unixorn/cupsd

or use docker-compose up with the following docker-compose.yaml:

version: '3.9'
services:
  cupsd:
    image: unixorn/cupsd
    volumes:
      - './printers.conf:/etc/cups/printers.conf'
      - '/dev/bus/usb:/dev/bus/usb'
      - '/var/run/dbus:/var/run/dbus'
      - /etc/hostname:/etc/hostname:ro
      - /etc/localtime:/etc/localtime:ro
      - /etc/machine-id:/etc/machine-id:ro
      - /etc/timezone:/etc/timezone:ro
    privileged: true
    ports:
      - '631:631'
    restart: unless-stopped

Mounting printers.conf into the container keeps you from losing your printer configuration when you upgrade the container later.
