Java Operator SDK is a higher level framework and related tooling to support writing Kubernetes Operators in Java. It makes it easy to implement best practices and patters for an Operator. Features include:
- Optimal handling Kubernetes API events
- Handling dependent resources, related events, caching.
- Automatic Retries
- Smart event scheduling
- Handling Observed Generations automatically
- Easy to use Error Handling
- ... and everything that a batteries included framework needs
For all features and their usage see the related section on the website.

While we know of multiple projects using JOSDK in production, we don't want to presume these projects want to advertise that fact here. For this reason, we ask that if you'd like your project to be featured in this section, please open a PR, adding a link to and short description of your project, as shown below:
- ExposedApp operator: a sample operator written to illustrate JOSDK concepts and its Quarkus extension in the "Write Kubernetes Operators in Java with the Java Operator SDK" blog series.
- Keycloak operator: the official Keycloak operator, built with Quarkus and JOSDK.
- Apache Flink Kubernetes operator is the market lead among Flink operators.
- Strimzi Access operator. While the core Strimzi operator development predates
JOSDK, but new components like the Access operator is using the framework.
