Kubernetes HPA vs. VPA. Kubernetes HPA (Horizontal Pod Autoscaler) and VPA (Vertical Pod Autoscaler) are both tools used to automatically adjust the resources allocated to pods in a Kubernetes cluster.

A Kubernetes node allocates resources for a pod based on its …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.Jul 7, 2016 · Delete HPA object and store it somewhere temporarily. get currentReplicas. if currentReplicas > hpa max, set desired = hpa max. else if hpa min is specified and currentReplicas < hpa min, set desired = hpa min. else if currentReplicas = 0, set desired = 1. else use metrics to calculate desired. Fortunately, Kubernetes includes Horizontal Pod Autoscaling (HPA), which allows you to automatically allocate more pods and resources with increased requests and then deallocate them when the load falls again based on key metrics like CPU and memory consumption, as well as external metrics.
