stop-instances is an AWS Lambda function for use with Lambder.

• python-lambder

This lambda function stops any EC2 instances that match the following:

• instance is running
• instance is tagged with Key: 'LambderStop'

It is usually paired with lambder-start-instances and used to run instances only during business hours to save money.

1. Clone this repo
2. cp example_lambder.json lambder.json
3. Edit lambder.json to set your S3 bucket
4. lambder function deploy

Schedule the function with a new event. Rember that the cron expression is based on UTC.

lambder events add \
  --name StopInstances \
  --function-name Lambder-stop-instances \
  --cron 'cron(0 0 ? * MON-FRI *)'

• Parameterize the tag in the input event object
