A pod is a logical construct in Kubernetes and requires a node to run, and a node can have one or more pods running inside of it. Horizontal Pod Autoscaler is a type of autoscaler that can increase or decrease the number of pods in a Deployment, ReplicationController, StatefulSet, or ReplicaSet, usually in response to CPU utilization patterns.

HPA is a native Kubernetes resource that you can template out just like you have done for your other resources. Helm is both a package management system and a templating tool, but it is unlikely its docs contain specific examples for all Kubernetes API objects. You can see many examples of HPA templates in the Bitnami Helm Charts.

The Horizontal Pod Autoscaler and Kubernetes Metrics Server are now supported by Amazon Elastic Kubernetes Service (EKS). This makes it easy to scale your Kubernetes workloads managed by Amazon EKS in response to custom metrics. One of the benefits of using containers is the ability to quickly autoscale your application up or …1. I hope you can shed some light on this. I am facing the same issue as described here: Kubernetes deployment not scaling down even though usage is below threshold. My configuration is almost identical. I have checked the hpa algorithm, but I cannot find an explanation for the fact that I am having only one replica of my-app3.With this metric the HPA controller will keep the average utilization of the pods in the scaling target at 60%. ... Keep in mind, that Kubernetes does not look at every single pod but on the average of all pods in that group. For example, given two pods running, one pod could run on 100% of requests and the other one at (almost) 0%.As Heapster is deprecated in later version(v 1.13) of kubernetes, You can expose your metrics using metrics-server also, Please check following answer for step by step instruction to setup HPA: How to Enable KubeAPI server for HPA Autoscaling MetricsIn order to scale based on custom metrics we need to have two components: One that collects metrics from our applications and stores them to Prometheus time series database.

Any HPA target can be scaled based on the resource usage of the pods in the scaling target.When defining the pod specification the resource requests like cpu and memory shouldbe specified. This is used to determine the resource utilization and used by the HPA controllerto scale the target up or down. By default, HPA in GKE uses CPU to scale up and down (based on resource requests Vs actual usage). However, you can use custom metrics as well, just follow this guide. In your case, have the custom metric track the number of HTTP requests per pod (do not use the number of requests to the LB).
