 A simple wrapper over `docker` to all complex cron job to be run in other containers.

 A great project, don't get me wrong. It was just missing certain key enterprise features I felt were required to support where docker is heading.
 
 ## Features

 - Easy to read schedule syntax allowed.
 - Allows for comments, cause we all need friendly reminders of what `update_script.sh` actually does.
 - Start an image using `image`.

 1. Figure out which network name used for your docker-compose containers

-	* if your `docker-compose.yml` is in `my_dir` directory, you probably has network `my_dir_default`
