Pretix Customized for CCCHH

The image adds an entrypoint script that creates /etc/pretix/pretix.cfg from environment variables at startup. The file is only created if it doesn't exist or is empty; this means that you can still mount your own config file into the container as with the original image.

The script will fail and point out if required variables are not set.

The image is available at gitlab-cr.hamburg.ccc.de/ccchh/ccchh-pretix/ccchh-pretix:23.10.0.

The config file is created from a template, with environment variables substituted.
