Introduction & Resources

Operators manage both cluster and non-cluster resources on behalf of Kubernetes. Java Operator SDK (JOSDK) aims to make it as easy as possible to implement a Kubernetes operators in Java. The APIs are designed to feel natural to Java developers. In addition the framework tries to handle common problem out of the box, so you don’t have to worry about generic sub-problems.
