Docker cronjob rights not correct if not running under root

I have an docker container running with Apache. This was started with docker-compose under the root user. In this container de webserver runs under the default user www-data. Via conjob I trigger the php script for uploading images. This works fine if the cronjob runs under root. But I want to have the conjob running under www-data so the uploaded files have the same owner as files that are uploaded directly via apache.

I use the following cronjob (this works):

*/1 * * * * docker exec apache_1 php /var/www/import

But when I change the cronjob user to www-data (does not trigger anymore):

*/1 * * * * www-data docker exec apache_1 php /var/www/import

With the last cronjob the php script inside the container is not triggered anymore. I believe it has to do with permission settings?

If you want the import command to be executed by www-data inside the container, specify it to docker:

*/1 * * * * docker exec --user www-data apache_1 php /var/www/import

With what you've tried, the user www-data has not permissions to run docker commands. And, you have not such option to specify the username in crontab -e (what you tried to do should be in /etc/crontab, or use su/sudo).

If your trying to run the command as the user while signed into the root user account your command should be:

su www-data; docker exec apache_1 php /var/www/import

Otherwise you need to switch to the www-data user(sudo su www-data) and then edit the cron jobs for the user(crontab -e). Each user has their own cronjobs.
