Kubernetes pod autoscaler using custom metrics
In this post we are going to demonstrate how to deploy a Kubernetes autoscaler using a third party metrics provider. You will learn how to expose any custom metric directly through the Kubernetes API implementing an extension service. Dynamic scaling is not a new concept by any means, but implementing your own scaler is a rather complex and delicate task.
That’s why the Kubernetes Horizontal Pod Autoscaler (HPA) is a really powerful Kubernetes mechanism: it can help you to dynamically adapt your service in a way that is reliable, predictable and easy to configure.
