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.I'm learning k8s hpa autoscale and have one confusion。 if there are some codes run in pod like this: # do something1 time.sleep(15) # do something2 when execution come to time.sleep(15) and at this time the hpa scale down, will this pod be removed and something2 will not execute？The metrics will be exposed at /apis/metrics.k8s.io as we saw in the previous section and will be used by HPA. Most non-trivial applications need more metrics than just memory and CPU and that is why most organization use a monitoring tool. Some of the most commonly used monitoring tools are Prometheus, Datadog, Sysdig etc.In kubernetes it can say unknown for hpa. In this situation you should check several places.
