# Containerfile for a CUPS print server sharing a Brother HL-4150CDN over
# IPP/AirPrint. Build with Podman:
#
# podman build -t printserver:latest .
#
# Run with host networking so mDNS (Avahi) can advertise the printer. The
# printer is described by environment variables:
#
# podman run --rm --network host \
# -e PRINTER_IP=192.168.1.50 \
# -e PRINTER_NAME=HL-4150CDN \
# --name printserver printserver:latest
#
# PRINTER_URI can be used instead of PRINTER_IP for full control:
#
# -e PRINTER_URI=lpd://192.168.1.50/binary_p1

# package, which depends on it. `--force-all` is used because the packages are
# built for i386 and have no dependency information Debian can satisfy here.
# The whole assets tree is copied because the directory name contains a space,
# which some COPY implementations cannot quote.
