Writing a Kubernetes Operator in Java

Explore the process of developing a Kubernetes Operator in Java through this 31-minute Devoxx conference talk. Dive into the world of Kubernetes API extensions, custom resource definitions (CRDs), and application-specific controllers. Learn how Quarkus and the fabric8 Kubernetes Client provide a solid foundation for implementing operators in Java, enabling integration of existing codebases with Kubernetes API extensions. Gain insights from Instana's experience in creating their instana-agent-operator, including lessons learned and best practices. Discover the potential of Java-based Kubernetes Operators for extending and customizing cluster behavior. Follow along as Dr. Fabian Stäber, a Java developer at Instana, shares his expertise on topics such as custom resources, testing, and practical demonstrations. Access the open-source project on GitHub to further explore the implementation details.
