Demo of AWS EC2 Instance Start/Stop scheduling

EC2 instance Start / Stop scheduler

Simple demo of EC2 instance scheduled starting / stopping using Lambda function and scheduled CloudWatch Events.

Usage

Deploy ec2-start-stop.yml using CloudFormation, change the stack parameters as necessary.

For help with the Start / StopCronExpression syntax check out Schedule Expressions for Rules.

Note that the Start/Stop time is in UTC Timezone (yeah, what an annoyance for us in regions that change to and from Daylight Saving Time 2x per year...).

Make changes

The main template ec2-start-stop.yml has been generated from src/ec2-start-stop.template.yml to which the lambda function code from src/ec2-start-stop.lambda.py has been inserted using src/import-files.py.

Don't edit the generated ec2-start-stop.yml template!

Instead modify the "template-template" src/ec2-start-stop.template.yml and/or src/ec2-start-stop.lambda.py and run make or

~/ec2-start-stop $ make
./import-files.py --yaml ec2-start-stop.template.yml > ec2-start-stop.yml

Then deploy the generated ec2-start-stop.yml
