Dekorate is a Java annotation-processing framework that generates Kubernetes, OpenShift, Knative, and other container orchestration manifests at compile time. It is primarily a library consumed by Java applications, especially those built with Spring Boot, Quarkus, Thorntail, or plain Java. The architecture centers around a `Session` that coordinates `ConfigurationGenerator`s, `ManifestGenerator`s, and a graph of `Decorator`s to produce deployment descriptors. It supports multiple platforms via separate annotation modules (e.g., kubernetes-annotations, openshift-annotations, knative-annotations) and integrates with build tools like Docker, Jib, S2I, and Tekton for CI/CD pipelines. The codebase is well-structured with clean abstractions (Decorator, Configurator, SPI factories) and extensive testing, though it suffers from a high module count and some outdated dependencies (e.g., Java 1.8 baseline, old Spring Boot versions in examples). Overall, it is a mature and capable tool for generating Kubernetes manifests from Java annotations.
