Maintainability and adaptability are crucial for continuous deployment in dynamic cloud environments, emphasizing the need for modularity.

Kubernetes CRDs and controllers provide declarative APIs. But extensibility and reusability limitations pose a challenge and impair custom resource modularity. Extending CRD schemas induces API changes or requires weaker schemas, control logic is not reusable for similar resource types, and many operators are complex monolithic controllers.

This work solves these limitations by implementing inheritance to enable extension and reuse of CRD schemas and controllers. Schema inheritance enables extending an existing CRD schema without changing its API, providing APIs at different levels of abstraction. This allows reuse of common controller functionality through generalisation, promoting separation of concerns in operators. Finally, inheritance enables reasoning about substitutability of custom resources, providing opportunities for adaptability.
