Fixed #10231: use correct python binary for exit listener This fixes #10231, without creating an own Dockerfile. 2021-11-01 14:15:35 -07:00			`#!/usr/bin/env python3`
Run Laravel schedule in docker image using supervisord (#6606) * docker: Rename /entrypoint.sh to /startup.sh This script is not configured as the docker image ENTRYPOINT, thus it is misleading to name it so. * docker: Terminate supervisord if a process enters the FATAL state By terminating PID 1, this will also terminate the Docker container. * docker: Use supervisord to start up apache and cron Note that this uses `apache2ctl -DFOREGROUND` rather than manually sourcing /etc/apache2/envvars and running apache2, as recommended at https://advancedweb.hu/2018/07/03/supervisor_docker/. * docker: Add artisan schedule:run to crontab This also switches to executing /var/www/html/artisan directly. * docker: Run artisan schedule:run directly from supervisor This has the following benefits over using cron: - Cron doesn't need to be installed - Docker-provided environment variables are preserved - It's easy and explicit to run as the docker user 2019-03-07 12:42:00 -08:00			`# A supervisor event listener which terminates supervisord if any of its child`
