VPA Recommendations

What’s it all about?

A dashboard to visualize metrics about the Vertical Pod Autoscalar (https://github.com/kubernetes/autoscaler/tree/master/vertical-pod-autoscaler) using the generated Prometheus metrics of the Kube-State-Metrics (https://github.com/kubernetes/kube-state-metrics/blob/master/docs/verticalpodautoscaler-metrics.md)

What do I need as a perquisite?

• Prometheus installed => ultimately using the kube-prometheus stack (https://github.com/prometheus-community/helm-charts/tree/main/charts/kube-prometheus-stack)
• The kube-state-metrics must be configured to enable Vertical Pod Autoscalar metrics. Example for the Helm Chart above:

kube-state-metrics:
  namespaceOverride: ""
  rbac:
    create: true
  ...
  collectors:
    verticalpodautoscalers: true

• VPA Installed and at least one VerticalPodAutoscalar CRD is configured against a certain target (check the documentation of the VPA for more info)
• Optionally: VPA is using Prometheus as a historical query backend to monitor changes over time.

My installation & configurations for the VPA

I am using the Helm chart at https://github.com/FairwindsOps/charts/tree/master/stable/vpa for the installing the VPA. There are other ways to do so. Just thought of sharing my values.yml for customizing this chart as the Prometheus part wasn’t that trivial.
