This project contains Kubernetes operator samples that demonstrate best practices how to develop operators with Go and the Operator SDK.


The project contains a custom application controller, a database controller simulating an external resource and a sample microservice. The easiest way to get started is to run the application controller only and refer to the database resource definition and the built microservice image on Docker.io.

Follow these instructions to run the application controller.
