CMD ["/usr/sbin/crond", "-f", "-d", "0"]

I am using this cron in multiple images. ++

Tested with the latest version, for some reason it doesnt work

/bin/sh: [/usr/sbin/crond,: not found

@getvivekv The last line is at fault, it should be the following:

CMD ["/usr/sbin/crond", "-f", "-d", "0"]

Thank you, you saved my day. Tested and works on Alpine 3.13 with supervisord.

log level

/* Log levels:
 * 0 is the most verbose, default 8.
 * For some reason, in fact only 5, 7 and 8 are used.
 */

Using it with an online view on some logs:

ENTRYPOINT ["/bin/sh", "-c", "crond -f -d 0 && tail -F /var/log/1.log & tail -F /var/log/2.log"]
