All CronJob schedule: times are based on the timezone of the kube-controller-manager (more on that here ). GKE’s master follows UTC timezone and hence our cron jobs were readjusted to run at 9AM ... Any HPA target can be scaled based on the resource usage of the pods in the scaling target.When defining the pod specification the resource requests like cpu and memory shouldbe specified. This is used to determine the resource utilization and used by the HPA controllerto scale the target up or down. cpu: 100m. limits: memory: 860Mi. cpu: 500m. The number of replicas of the deployment is like below. When I listed the hpa, it is showed like below. the output is like below. Eventhough the load is low, initially pod count is 4.
