About this talk

This talk focuses on the integration of OpenAPI with Kubernetes to improve the process of auto-generating Custom Resource Definitions (CRDs) and operators. The speakers, Sergiusz Urbaniak and Jose Vázquez González from MongoDB, highlight the challenges developers face when creating operators for APIs exposed through structured, non-Kubernetes interfaces. They present "crd2go," an automated pipeline designed to convert OpenAPI services into operators that manage CRD-backed Kubernetes APIs. The session covers the full conversion process, including how to generate Go code from CRDs and implement a universal state machine logic to enhance controller functionality.
