Towards Something Better Than CRDs in a Post-Operator World

Explore the future of Kubernetes extension mechanisms in this conference talk by Stefan Schimanski from Red Hat. Delve into the limitations of CustomResourceDefinitions (CRDs) and the search for their successor in a post-operator world. Examine how CRDs, currently driving the Kubernetes extension ecosystem, fall short in meeting the needs of service providers building and offering services to tenants. Understand the challenges of user-controlled CRDs, including customization issues and the complexities of updating operators and APIs. Learn about the vision for elevating CRDs to become first-class vehicles for APIs, enabling provision and consumption by different parties across clusters without relying on operator-glue. Discover the potential for standardized, secure, and federated APIs that address today's problems and move beyond the original conception of CRDs as in-cluster concept tools.
