This is a tiny lambda which can reboot EC2 instances on a cron schedule.
Use this project as an example to create other scheduled maintenance scripts in your AWS environment.
For simplicity, this lambda gets ec2:RebootInstances permissions automatically. If your environment requires more granular permissions, please add each instance ARN to template.yaml line 37
See deploy.sh for instructions on how to deploy
- PROFILE: Which AWS Profile to use during the deploy
- REGION: Which AWS Region to deploy to
- BUCKET: Artifact bucket used by SAM - this should be created beforehand
- STACK_NAME: The name of your CloudFormation stack
- SCHEDULE: CRON expression
- EC2_ID_CSV: Comma separated list of EC2 instance IDs
Deployment errors will be visible in your AWS CloudFormation console. Look for your stack name, and see the events tab.
Lambda execution errors can be found in the AWS Lambda console. Search for the lambda function who's name starts with {StackName}-ScheduledReboot-{...} and check the Monitoring tab for execution history and error rates.
Additional Information: RebootInstances Service Reference
To remove the lambda, simply delete the CloudFormation stack.
