Kubernetes is much more than a runtime platform for Docker containers.
Through its API, you can not only create custom clients, but you can also extend Kubernetes. Those custom Controllers are called Operators and work with application-specific custom resource definitions. You can not only write those Kubernetes operators in Go, but you can do this also in Java.
Rudy explores the concepts of resource listeners, programmatic creation of deployments and services, and how this can be used for your custom requirements.
