Auto-stop successful GKE review environments after X days
To be more efficient with GKE cloud-native cluster resources, we should automatically stop review environments that have been up for X days. We need to decide what X makes sense for our enviroment.
Currently, running stale review environments in GKE are taking up cluster resources, causing high CPU and memory usage. This causes other gke_review jobs to fail when the cluster resources are not available. This seems to happen often, requiring manual intervention from Distribution engineers.
