Im using php-apache image to create an owncloud installation. I want to use a system cronjob to execute cron.php, therefore I run:
RUN echo "*/3 * * * * php -f /var/www/html/cron.php >> /oc_data/cron.log" > /cron.conf \ && crontab -u www-data /cron.conf
The entrypoint script starts cron with:
It gets executed but the owncloud.log shows following message:
"app":"cron","message":"Failed to connect to the database: An exception occured in driver: could not find driver"
Fun thing is, if I enter the docker container and execute the command I use for the cronjob, it works. And
php --ini shows all php conf.d extensions including mysql.so and pdo_mysql.so.
I also tried to add the cron.conf file as user root with the same result.
Any ideas, what is happening here?
