Hey, I just wrote an article about a how we implemented extension api-server for Cozystack - free PaaS platform, which we extended with Kubernetes API Aggregation Layer.

I inspired to write this article after noticing a lack of detailed information of this amazing feature in Kubernetes. I hope this article helps guide people through creating their own Aggregation API server.

This article aims to present a more generic information for implementing the Aggregation API. It covers common use cases and the steps for implementing your own extension api-server.

Any feedback is welcome!
