In this article. Kubernetes Event-driven Autoscaling (KEDA) is a single-purpose and lightweight component that strives to make application autoscaling simple and is a CNCF Graduate project. It applies event-driven autoscaling to scale your application to meet demand in a sustainable and cost-efficient manner with scale-to-zero. Best Practices for Kubernetes Autoscaling Make Sure that HPA and VPA Policies Don’t Clash. The Vertical Pod Autoscaler automatically scales requests and throttles configurations, reducing overhead and reducing costs. By contrast, HPA is designed to scale out, expanding applications to additional nodes. For Kubernetes, the Metrics API offers a basic set of metrics to support automatic scaling and similar use cases.

STEP 2: Installing Metrics Server Tool. Install the DigitalOcean Kubernetes metrics server tool from the DigitalOcean Marketplace so the HPA can monitor the cluster’s resource usage. Confirm that the metrics server is installed using the following command: kubectl top nodes It takes a few minutes for the metrics server to start reporting the metrics.

The Horizontal Pod Autoscaler (HPA) in Kubernetes does not work out of the box. It has to make decisions on when to add or remove replicas based on real data. Unfortunately, Kubernetes does not collect and aggregate metrics. Instead, Kubernetes defines a Metrics API and leaves it to other software for the actual implementation. In kubernetes it can say unknown for hpa. In this situation you should check several places. In K8s 1.9 uses custom metrics. so In order to work your k8s cluster ; with heapster you should check kube-controller-manager. Add these parameters.--horizontal-pod-autoscaler-use-rest-clients=false--horizontal-pod-autoscaler-sync-period=10s 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.

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 …Kubernetes’ default HPA is based on CPU utilization and desiredReplicas never go lower than 1, where CPU utilization cannot be zero for a running Pod.

18. For the HPA to work with resource metrics, every container of the Pod needs to have a request for the given resource (CPU or memory). It seems that the Linkerd sidecar container in your Pod does not define a memory request (it might have a CPU request). That's why the HPA complains about missing request for memory.
