Define sleep & wake up cycles for your Kubernetes resources. Automatically schedule to shutdown Deployments, CronJobs, StatefulSets and HorizontalPodAutoscalers that occupy resources in your cluster and wake them up only when you need them, reducing that way the overall power consumption.

Following the paradigm of CronJobs specifications in Kubernetes, shutdown and wakeup schedules need to support other timezones apart from the default UTC
Add the option to terminate workflow on a specific date in the future:

Hi,
when evaluating the project, we were wondering if the MinReplicaCount for HorizontalPodAutoscalers could be modified from its default of 1 in case of shutdown?
Thanks,
Cornelius
Hey there 👋🏻
I'm running on AWS EKS cluster v1.25.
The sleepcycles were installed on the cluster and the label were configured on one of the deployments.
Here are some logs from sleepcycles pod:

^Cmake: *** [Makefile:103: undeploy] Error 1
Hello @akyriako
First of all, thank you for this tool, it helps us to decrease costs.
But I implemented it in different namespaces, and time to time wakeup schedule is ignored, and last action is Watch.
For example, logs from one env:
NAME SHUTDOWN SCHEDULE SHUTDOWN TIMEZONE WAKEUP SCHEDULE WAKEUP TIMEZONE ENABLED SUCCESS LAST OP
sleepcycle 0 23 * * 1-5 Europe/Warsaw 0 7 * * 1-5 Europe/Warsaw true true Watch
Could you please help me? Maybe, you can help how I can debug this problem.
Best regards,
Hanna
