A multi stage build is used to separate the build environment from the runtime environment. It is not used to merge multiple images together. — BMitch, Jul 17 '22 at 10:35

Try something like this:

RUN echo "* * * * * root php /var/www/test schedule:run >> /var/log/cron.log 2>&1" >> /etc/crontab

# Create the log file to be able to run tail

RUN touch /var/log/cron.log

Thanks for your answers, that's correctly add the command in the crontab file in the container but no cron are running still. Have you an idea ? – Yannis Haismann Jul 17 '22 at 13:16
