spottpreis - Discover spot prices for AWS EC2 Instance

Description

This is a small helper for discovering the cheapest instance type in a region and within availability zones. It can be used to automate bidding on spot instances, returning the last bid for your selection.

What's with the name?

It's a German idiom describing a price that's either knocked down or ridiculously low, "spott" meaning ridicule or mockery and price obviously translates into price.

Installation

git clone ssh://git@github.com/nilsmeyer/spottpreis
cd spottpreis
pip3 install --user .

Usage

This application uses click, you can check the arguments using the --help command line switch. Output can be formatted in json or as text, it will return a list starting with the least expensive.

You must have an AWS client environment configured and a profile available.

  -r, --region TEXT             AWS region to use
  -z, --availability-zone TEXT  Availability Zones to use, use 'all' for all
