K8s hpa

Could kubernetes-cronhpa-controller and HPA work together? Yes and no is the answer. kubernetes-cronhpa-controller can work together with hpa. But if the desired replicas is independent. So when the HPA min replicas reached kubernetes-cronhpa-controller will ignore the replicas and scale down and later the HPA controller will scale it up.

When jobs in queue in sidekiq goes above say 1000 jobs HPA triggers 10 new pods. Then each pod will execute 100 jobs in queue. When jobs are reduced to say 400. HPA will scale-down. But when scale-down happens, hpa kills pods say 4 pods are killed. Thoes 4 pods were still running jobs say each pod was running 30-50 jobs.The Kubernetes Horizontal Pod Autoscaler (HPA) automatically scales the number of pods in a deployment based on a custom metric or a resource metric from a pod using the Metrics Server.
