Docker raphiz/ubuntu-cron

Ubuntu latest with cron, powerd by supervisor.

You can easily replace the default /etc/crontab with one that suits your needs. The image will log the syslog into stdout which makes it easy for you to inspect the logs with docker logs <container>.

If you want that other files also appear in the stdout, you can set the environment variable FILES_TO_LOG with a semicolon separated list of files to log (eg. FILES_TO_LOG=/var/log/app_info.log;/var/log/app_error.log)
