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.

Step-1 : Enable Minikube with the following settingsWhen both configured some unexpected behaviour might arise. If there is an HPA, it manages the amount of replicas according to it's settings. But while deployment is under control of an HPA, if you apply deployment config with set amount of replicas, it would override current desired amount of replicas and might scale your deployment unexpectedly.Good afternoon.
