Quick reference

What is Jobber?

Jobber is a utility for Unix-like systems that can run arbitrary commands, or “jobs”, according to a schedule. It is meant to be a better alternative to the classic Unix utility cron.

Along with the functionality of cron, Jobber also provides:

  • Job execution history: you can see what jobs have recently run, and whether they succeeded or failed.
  • Sophisticated error handling: you can control whether and when a job is run again after it fails. For example, after an initial failure of a job, Jobber can schedule future runs using an exponential backoff algorithm.
  • Sophisticated error reporting: you can control whether Jobber notifies you about each failed run, or only about jobs that have been disabled due to repeated failures.

How to use this image

This image contains Jobber running as an unprivileged user named “jobberuser”. The jobs are defined in the file /home/jobberuser/.jobber. By default, the only job is one that prints “Jobber is running!” every second. You should replace it with your own jobs. Refer to the documentation to learn how to do this.
