Readme.md

The aim of my-bloody-hetzner-sb-notifier is a simple CLI to fetch the current Hetzner Serverbörse deals and filter them according to CLI parameters sorted by score.

For each offer a score is calculated from the amount of HDD space as well as RAM and CPU-Benchnmark for better comparability.

The CLI interface looks like this:

Usage of hetzner-sb-notifier:
  -min-cpu-benchmark int
    	set min benchmark
  -max-cpu-benchmark int
    	set max benchmark (default 20000)
  -max-hdd-count int
    	set max hdd count (default 15)
  -max-hdd-size int
    	set max hdd size (default 6144)
  -max-price float
    	set max price (default 297)
  -max-ram int
    	set max ram (default 256)
  -min-hdd-count int
    	set min hdd count
  -min-hdd-size int
    	set min hdd size
  -min-price float
    	set min price
  -min-ram int
    	set min ram
  -serve-http
    	set serve http
  -serve-http-port int
    	set serve http port (default 8080)
  -output
    	set output: one of table, json (default table)

Http mode

In HTTP mode (app started with flag -serve-http) hetzner-sb-notifier runs continuously and can be queried via simple HTTP GET request. CLI parameters are translated to camel case. For example min-hdd-count becomes minHddCount

CLI-Example

./hetzner-sb-notifier --max-price 77 --min-ram 128 --min-hdd-count 2 --min-hdd-size 4096
