Introduction

This is a Python 2.7 script to start / stop AWS EC2 instances depending on the tag: op_hours.

Requirements

• python 2.7
• virtualenv
• pip
• awscli setup properly

Tagging

Currently the supported tag is simply:

Key: op_hours
Value: <start-day-of-week>-<stop-day-of-week>:<start-hour-of-day>-<stop-hour-of-day>

e.g. Value: 1-5:0800-1800 will ensure that the instance runs Monday to Friday, 8:00am to 6:00pm. It will shutdown / startup the instance depending on the op_hours tag.

Setup

$ virtualenv venv
$ source venv/bin/activate
$ pip install -r requirements.txt

If you have more than 1 version of python (i.e. python 2.7 and python 3 installed) and want to specify which Python version you can use virtualenv --python=/usr/bin/python2.7 venv.

Run

$ python start-stop-ec2-instances.py

cli

In the cli directory, the bash script is used to generate a session token since my AWS account is setup to enforce MFA and only allow resources with token session, I need to run cli/aws-get-session.sh <token-code> <userid> first (and follow the instruction to set the shell variables).
