## What it is
kube-green is a Kubernetes operator that automatically shuts down or scales down cluster resources (like dev and preview pods) during off-hours such as nights and weekends. It uses a SleepInfo CRD with timezone-aware schedules to reduce energy consumption, costs, and CO2 emissions.

## Use cases
- shut down dev pods on weekends and nights
- reduce kubernetes cluster energy costs
- lower CO2 footprint of k8s clusters
- schedule automatic pod downscaling outside working hours
- suspend preview environments when nobody is using them

## When to choose
- you run dev, staging, or preview environments in Kubernetes that sit idle outside working hours
- you want to cut cloud costs and emissions with declarative CRD-based schedules
- you need timezone-aware automatic shutdown of namespaces or deployments

## When to avoid
- your workloads must run 24/7 with no downtime
- you are not running Kubernetes
- you need fine-grained per-request autoscaling rather than time-based shutdown
