+- `kompose.hpa.replicas.min` defines the floor for the number of replicas that the HPA can scale down to during a scaling event. Default value is set to 1. This means that, regardless of the load on the system, the HPA will always maintain at least one replica. More info: [HPA Min Replicas](https://kubernetes.io/docs/tasks/run-application/horizontal-pod-autoscale-walkthrough/#autoscaling-on-multiple-metrics-and-custom-metrics).

+```
+
+- `kompose.hpa.replicas.max` defines the upper limit for the number of replicas that the HPA can create during a scaling event. Default value is set to 3. This default value serves as a safeguard, providing a conservative starting point for your HPA configuration.

 ## Restart

 If you want to create normal pods without controller you can use `restart` construct of compose to define that. Follow table below to see what happens on the `restart` value.
