AWS Cloudwatch Alarm Manager

This service is meant to set the Cloudwatch Alarm to a desired state (which can be invoked by an eventbrigde or etc) to allow the cloudwatch alarm to re-invoke a lambda function. It's a workaround to work as the scale-in & scale-out cooldown period for the docdb-autoscaler service. This service was built to work together with the docdb-autoscaler service Link. However, it can be used for other services as well.

To Use

Pull the docker image into your AWS ECR. AWS Lambda container images must reside in AWS ECR.

Testing

   go fmt ./...
   go clean -cache -testcache
   go test ./... -v

Debugging

1. Go to the AWS Lambda function -> Monitor & check if the Lambda function was invoked
2. Further debug using cloudwatch logs.
