SpotCheck

A simple CLI tool to check the spot prices of AWS EC2 instances. This tool is utilized to check the recent prices of spot instances for different instance type, so the user can make an informed decision on the price to set for spot instances.

Background

Spot Instances are a good resource to use AWS EC2 instances for fairly cheap, and I am very frugal. This tool allows me (and you, the user) to check historical prices of spot instances to make an informed decision on the prices to set when creating an EC2 instance.

Installation

To install, use pip such that

pip3 install --user spotcheck

Setup

Since spotcheck uses boto3, you'll have to setup the same way. You can view the docs here

Usage

To use, run

spotcheck

and a series of questions will be prompted.

The results is of the form

+------------------+-------------------+---------------+--------------+---------------+
| Timestamp        | Availability Zone | Instance Type | Product Desc | Spot Price($) |
+------------------+-------------------+---------------+--------------+---------------+

Repeatable Usage

If you don't want to enter the CLI every time, you can run the CLI with the options

spotcheck --InstanceType=t2.micro --ProductDescription=Linux/UNIX --StartTime=$(date -d "3 days ago" +"%Y-%m-%d") --EndTime=$(date +"%Y-%m-%d")
