docker root crontab job not executing

cron docker ubuntu-14.04 crontab dockerfile

Why use cron? Just write a shell script like this:

#!/bin/bashwhile true; do  python /opt/com.org.project/main.py >> /opt/com.org.project/var/log/cron.log  sleep 60done

Then just set it as entrypoint.

ENTRYPOINT ["/bin/bash", "/loop_main.sh" ]

cron docker ubuntu-14.04 crontab dockerfile

Where did you use crontab -e? On the host running docker or in the container itself?

I can't see that you are adding an crontab entry in the dockerfile you provided. I recommend you to add an external crontab file like this:

ADD crontabfile /app/crontabRUN crontab /app/crontabCMD ["cron", "-f"]

The file crontabfile has to be located next to Dockerfile.

image_folder||- Dockerfile|- crontabfile

Example content of crontabfile:

# m h  dom mon dow   command30  4 * * * /app/myscript.py
