mantra - A simple cron-like scheduler for a single command
Running a process in a Docker container on a fixed schedule is fiddly. Most solutions seem to involve installing cron, then installing a crontab and tailing cron's output. Yuck. mantra is more like at, in that it allows you to specify the schedule as an argument in a cron format, along with the executable name and any arguments. It will then run that command, and only that command, on the schedule provided. STDOUT and STDERR are shared, making it easier to capture the program output.
