Hi, On GKE we have been supporting HPA with custom metrics since version 1.9. If you have a group of horizontally autoscaled pods inside your cluster each exporting a custom metric then you can set an average per pod target for that metric. An example of that would be an autoscaled deployment of a frontend where each replica exports its current QPS. One could set the average target of QPS per frontend pod and use the HPA to scale the deployment up and down accordingly. You can find the documentation and a tutorial explaining how to set this up here: https://cloud.google.com/kubernetes-engine/docs/tutorials/custom-metrics-autoscaling Kubernetes 1.10 becoming available on GKE will extend the support for custom metrics to include metrics not attached to any Kubernetes object. This will give you the ability to scale a deployment based on any metric listed here, for example number of messages in Google Pub/Sub queue.
