AWS EC2 instances start/stop scheduling

AWS EC2 start/stop functions

It's been surprisingly hard to schedule AWS EC2 instances launches/stops. This repo contains a set of artifacts to make it working in 10 minutes for simple cases when you need to launch/terminate a few instances. The following installation guide describes how to end up having an instance launched on working days at 09:45 and terminating at 10:10. Inspired by https://blog.goodmirek.com/periodically-start-and-stop-ec2-instance-bf25c01e68f1

Installation

1. Create a new IAM policy ec2_start_stop_policy using ec2_start_stop_policy.json
2. Create a new IAM role ec2_start_stop_role using ec2_start_stop_role.json
3. Create a new lambda function ec2-start, use ec2_start_stop_role as the default execution role and lambda/ec2-start/index.js as source code. Put your instance id and region into the source code.
4. Create a new lambda function, use ec2_start_stop_role as the default execution role and lambda/ec2-stop/index.js as source code. Put your instance id and region into the source code
5. Create a new rule in CloudWatch rules ec2-start. Use ec2_start_stop_role and ec2-start function as a target. Use 45 9 ? * MON-FRI * as a schedule expression
6. Create a new rule in CloudWatch rules ec2-stop. Use ec2_start_stop_role and ec2-stop function as a target. Use 10 10 ? * MON-FRI * as a schedule expression
7. If you need hibernation instead of termination use lambda/ec2-hibernate/index.js at step 4

Further enhancements

• make instance ids and region configurable
• make CloudFormation templates to do the job
