racedb_qlmux

racedb_qlmux/racedb_qllabels container

Overview

This container is set up to use:

This file is adapted from the RaceDB docker-compose.yml file. The main differences is that it uses a private image of the RaceDB container that includes the qllabels. See the Dockerfile in this directory for more information.

To use this file, you need to set the following environment variables in a .env file:

  RACEDB_PORT=8000
  RACEDB_HOSTNAME=racedb.local
  RFID_READER_HOST=127.0.0.1
  RFID_TRANSMIT_POWER=40
  RFID_RECEIVER_SENSITIVITY=20
  CSRF_TRUSTED_ORIGINS=https://racedb.example.com

N.b. The TRANSMIT_POWER and RECEIVER_SENSITIVITY are for the Impinj reader and should be set to the values for your reader and the RFID wands in use.

csrf.py

This is a simple script in the Dockerfile to append the CSRF_TRUSTED_ORIGINS to the settings.py file.

The CSRF_TRUSTED_ORIGINS needs to be set in the docker.env file.

The script is run when the private RaceDB image is built by docker.

#!/bin/sh
#
echo CSRF_TRUSTED_ORIGINS = [\"${CSRF_TRUSTED_ORIGINS}\", ]  >> /RaceDB/RaceDB/settings.py

See DockerFile:

# Append CSRF_TRUSTED_ORIGINS to RaceDB	Settings, 
# doing it in csrf.sh to get the quoting right.
COPY csrf.sh .
RUN /csrf.sh

Printer Configuration in RaceDB

RaceDB needs to be configured to send print data to the qlmux_proxy application. This is done by configuring the LP print command in Systeminfo->Printer Configuration.

A simple lpr script is installed that uses ssh to send the print data to the qlmux_proxy container.

#!/bin/sh
ssh -p 9122 -o StrictHostKeyChecking=no racedb@172.17.0.1 qllabels ${1}

N.b. 172.17.0.1 is the default address of the host machine on the docker0 network.

Table vs Kiosk

N.b. The Table vs Kiosk is a convention, there is no difference in the qlmux_proxy application and this could just be two tables or kiosks.

Backup

The database is NOT backed up to the /racedb-data/ directory every time the container is started.

This can be disabled by removing this file:

    ./racedb-data/.NOBACKUP
