Kube-Green
summary
Kube-Green is an open-source Kubernetes operator that saves resources by putting workloads to sleep: it uses a SleepInfo custom resource to set Deployment replica counts to zero, stores the original counts in a Secret, and restores them on wake. It runs on a cron schedule (demoed on Kind), supports Deployments today with namespace/workload exclusions, and reported cutting pods from 1,050 to 450 and reducing memory usage by ~33 GB consumed / ~45 GB allocated, estimating ~91 kg CO2e saved per week; planned features include CronJob support, historical metrics and immediate triggers.
