Documentation

Overview

crdpuller package provides a library to pull API resource definitions from existing Kubernetes clusters as Custom Resource Definitions that can then be applied to a KCP instance.

- If a CRD already exists for a given resource in the targeted cluster, then it is reused. - If no CRD exist in the targeted cluster, then the CRD OpenAPI v3 schema is built from the openAPI v2 (Swagger) definitions published by the targeted cluster.
