K8s hpa

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.

It means probably the same as the output from the kubectl describe hpa {hpa-name}: ... resource cpu on pods (as a percentage of request): 60% (120m) / 50%. It means that CPU has consumption increased to to x % of the request - good example and explanation in the Kubernetes docs: Within a minute or so, you should see the higher …

My understanding is that in Kubernetes, when using the Horizontal Pod Autoscaler, if the targetCPUUtilizationPercentage field is set to 50%, and the average CPU utilization across all the pod's replicas is above that value, the HPA will create more replicas. Once the average CPU drops below 50% for some time, it will lower the number of replicas.apiVersion: keda.k8s.io/v1alpha1 kind: ScaledObject metadata: name: ... Now the HPA makes a decision to scale down from 4 replicas to 2. There is no way to control which of the 2 replicas get terminated to scale down. That means the HPA may attempt to terminate a replica that is 2.9 hours into processing a 3 hour queue message.Custom Metrics in HPA.

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.

Without autoscaling, most companies recognize they're either wasting a lot of resources or risking performance/reliability issues.

When 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.

HPA does not kill (delete) the Pod, it scales the Deployment, which in turn scales underlying ReplicaSet. So the Pod deletion isbtriggered by RS scale change. ...
