AWS Infrastructure shutdown scheduler

A simple scheduler to shut down and start up AWS infrastructure on a recurring scheduler using Serverless framework. Can be used to mitigate running costs on off hours.

Supported types of infrastructure:

• ECS service capacity (i.e. Fargate containers)
• RDS clusters
• Autoscaling group capacity

Usage

1. Clone/fork the repository
2. Add necessary stack configuration in serverless.yml (such as VPC/subnet details if you cannot use the default VPC)
3. Modify cron timer defaults in serverless.yml (default: startup at 03 UTC MON-FRI and shutdown 18 UTC MON-FRI)
4. Rename infra-config-example.ts -> infra-config.ts
5. Configure your infrastructure details in infra-config.ts. Set desiredCount, DesiredCapacity and MinSize as the regular running values - the shutdown is going to set these to zero, and the startup back to the configured values.
6. npm install
7. Login into your AWS profile in your shell
8. sls deploy

If you want to manually start / shutdown the infrastructure (say, for working on something critical on a weekend) you can manually invoke the functions:

Start: sls invoke -f startup Shutdown: sls invoke -f shutdown
