Flapping of replicas happens not always, hard to catch a state before scaling. Don't see terminating pods and no errors in logs, so I believe it is because autoscaling. Had no pods restarts before HPA enabled. I didn't try newer version of K8s, version might be a reason. –

Kubernetes autoscaling allows a cluster to automatically increase or decrease the number of nodes, or adjust pod resources, in response to demand.

In short, HPA provides an automated way to add and remove pods at runtime to meet demand. Note that HPA works for the pods that are either stateless or support autoscaling out of the box. You would like to set an HPA target CPU utilization of 60% based on the limit. Applying the formula: (500 m /100 m) × 60 = 300. This calculation tells the HPA to target CPU utilization at 300% ...

First, get the YAML of your HorizontalPodAutoscaler in the autoscaling/v2 form: kubectl get hpa php-apache -o yaml > /tmp/hpa-v2.yaml. Open the /tmp/hpa-v2.yaml file in an editor, and you should see YAML which looks like this:In every Kubernetes installation, there is support for an HPA resource and associated controller by default. The HPA control loop continuously monitors the configured metric, compares it with the target value of that metric, and then decides to increase or decrease the number of replica pods to achieve the target value.

HPA is one of the autoscaling methods native to Kubernetes, used to scale resources like deployments, replica sets, replication controllers, and stateful sets. It increases or reduces the number of pods based on observed metrics and in accordance with given thresholds. Each HPA exists in the cluster as a HorizontalPodAutoscaler object. To ... The documentation includes this example at the bottom. Potentially this feature wasn't available when the question was initially asked. The selectPolicy value of Disabled turns off scaling the given direction.
