The Horizonal Pod Autoscaler (HPA) in Kubernetes has limited functionality in offering container CPU or Memory as metrics to monitor pod scaling performance. However, the CNCF Graduated Project KEDA, short for Kubernetes-based Event Driven Autoscaling, offers a wide array of options. One of these includes using metrics exposed by Prometheus, another CNCF Graduated project. Another is Micrometer, an Open Source metrics facade that integrates nicely with Spring Boot, which can expose many different metrics from an application. Adding one additional dependency can help to expose those metrics in a format that is understood by Prometheus. Putting all of these together, we can expose any metric we desire from our application and use that to drive the scaling of an application in Kubernetes.
