Instead of writing a bash script for automating a recurring job I decided to write a general purpose job executor in Python this time.
The idea was to define recurring jobs (for backup, update checks, etc.) in a config file, which can be executed by name. The jobs will then be called via Cron or Systemd once per day (or any other interval).
Also I wanted to be informed about the outcome of some jobs. But instead of filling up my mailbox I prefer to receive the notifications on my phone via Telegram.
So I ended up writing JobMonkey 
You can find the source on Github.
Jobs consist of one or more tasks. Where each task is a command to be executed.
Features:
- Configuration is stored in a YAML file.
- Jobs can be enabled or disabled.
- Job based reporting can be enabled ‘always’ or ‘on-failure’
- Reporting can also be enabled for single tasks
- Reports are sent via Telegram
The config YAML looks like this:
