Thanks. Shutting down K8S cluster when not using is a really good idea. Maybe one day I play around with AWS's k8s cluster and add the trick to aws-cost-saver.

Pull requests are also welcome if you have time :) the logic must be similar to EC2 or RDS tricks: https://github.com/aramalipoor/aws-cost-saver/blob/master/sr...
