kubernetes - Is it possible to Autoscale Akka

Question

I need an Akka cluster to run multiple CPU intensive jobs. I cannot predict how much CPU power I need. Sometimes load is high, while at other times, there isn't much load. I guess autoscaling is a good option, which means, example: I should be able to specify that I need minimum 2 and maximum 10 Actors. The cluster should scale up or down along with a cool off period as load goes up or down. Is there a way to do that? I am guessing, maybe one can make an Docker image of the codebase, and autoscale it using Kubernetes. Is it possible? Is there a native Akka solution? Thanks

Answer 1

If you consider a project like hseeberger/constructr and its issue 179, a native Akka solution should be based on akka/akka-management:

This repository contains interfaces to inspect, interact and manage various Parts of Akka, primarily Akka Cluster. Future additions may extend these concepts to other parts of Akka.

There is a demo for kubernetes.
