goScheduler

When you would use this scheduler instead of cron

You would use this scheduler on a team machine where the system administrators have prevented the use of cron. Valid reasons why they prevent the use of cron include:

• Jobs overlapping.
• Dataset that job processes becomes too large.
• Limits to the number of open file descriptors, threads and memory usage on a machine
• Other race condition problems since users assume the entire system's resources are at their disposal.

Beware: Due to above reasons, use this simple scheduler at your own risk as you could get in trouble with system administrators! I personally used it to refresh application data where the dataset was small and posed no risks.

Configuration

$ git clone git@github.com:chentda/goScheduler.git && cd goscheduler/config/
$ vim example.toml # fill out name of bash script and time you want to schedule it to run
$ mv example.toml ../config.toml 

To Test

$ make run

To Run As Binary

You would normally run this in a terminal multiplexer like tmux or screen

$ make compile
$ ./goScheduler # goScheduler is the name of the executable - could be different for you if you change it in the Makefile

Limitations

• Only schedules bash scripts, so if you need to run something else like a python script, just called it in the bash script.
• Only schedules 1 bash script currently, so you will have to duplicate the executable if you want to run multiple bash scripts.
• Only runs Mon-Fri.
