Inside Docker container - crond running but no cronjobs executed

Question

I have built a container from a Dockerfile, based on an Archlinux base image. Using a "RUN" command I have installed "cronie", since Arch does not come with any form of cron. Now, after the container is built, I run it and attach to it. I start manually the cron daemon, verify that it is indeed running with "ps -aux" and make the required cronjobs with "crontab -e". The thing is, no cronjobs are run...

Any ideas?

Solution

You can use the package fcron, and run the cron process in foreground mode:

fcron -f

check cron.log file and paste error here?

@AbhishekAnandAmralkar There is no "cron.log" file in Arch Linux. I tried "journalctl -u cronie" but it returns "No journal files were found". Still, the daemon is running, and the jobs configures inside crontab.

check for systemd/Timers ..Timers are systemd unit files with a suffix of .timer systemctl list-timers will list all the timers if any..

I mention that this is taking place inside a Docker container. No systemd is running.
