Popeye doesn't have recommendations about VPA.

On https://github.com/kubernetes/autoscaler/blob/master/vertical-pod-autoscaler/README.md#intro

Vertical Pod Autoscaler (VPA) frees users from the necessity of setting up-to-date resource limits and requests for the containers in their pods. When configured, it will set the requests automatically based on usage and thus allow proper scheduling onto nodes so that appropriate resource amount is available for each pod. It will also maintain ratios between limits and requests that were specified in initial containers configuration.

It can both down-scale pods that are over-requesting resources, and also up-scale pods that are under-requesting resources based on their usage over time.

Autoscaling is configured with a Custom Resource Definition object called VerticalPodAutoscaler. It allows to specify which pods should be vertically autoscaled as well as if/how the resource recommendations are applied.

To enable vertical pod autoscaling on your cluster please follow the installation procedure described below.
