K8s hpa.

The Horizontal Pod Autoscaler (HPA) automatically scales the number of replicas of an application; in other words the number of Pods in a replication controller, deployment, replica set or stateful set, based on observed values of a metric. HPA in Kubernetes only supports CPU and Memory metrics out-of-the-box.One that collects metrics from our applications and stores them to Prometheus time series database. The second one that extends the Kubernetes Custom Metrics API with the metrics supplied by a collector, the k8s-prometheus-adapter.

HPA sets two parameters: the target utilization level and the minimum or maximum number of replicas allowed. When the utilization of a pod exceeds the target, HPA will automatically scale up the number of replicas to handle the increased load. You did not change the configuration file that you originally used to create the Deployment object. Other commands for updating API objects include kubectl annotate , kubectl edit , kubectl replace , kubectl scale , and kubectl apply.
