`apiextensions.k8s.io/v1beta1` deprecation

[QlemWasTaken]

Hi,

I ran into an issues while trying to setup a macvlan through kubernetes API on Talos v.

I tried to setup NetworkAttachmentDefinition CRD with the example given at parapgraph 3.1.
This example use apiextensions.k8s.io/v1beta1 which seem to be depreceated.

Got the following error while applying the CustomResourceDefinition :

error: resource mapping not found for name: "network-attachment-definitions.k8s.cni.cncf.io" namespace: "" from "crd.yaml": no matches for kind "CustomResourceDefinition" in version "apiextensions.k8s.io/v1beta1"
ensure CRDs are installed first

Changing only the apiVersion to apiextensions.k8s.io/v1 got me other errors, probably due to changes in spec.version and spec.validation.

The CustomResourceDefinition "network-attachment-definitions.k8s.cni.cncf.io" is invalid:
* spec.validation.openAPIV3Schema.properties[spec].type: Required value: must not be empty for specified object fields
* spec.validation.openAPIV3Schema.type: Required value: must not be empty at the root

Throught trial and errors based on the following documents : ref1 , ref2 I got it working with the following definition :

apiVersion: apiextensions.k8s.io/v1
kind: CustomResourceDefinition
metadata:
  name: network-attachment-definitions.k8s.cni.cncf.io
spec:
  group: k8s.cni.cncf.io
  versions:
    - name: v1
      served: true
      storage: true
      schema:
        openAPIV3Schema:
          type: object
          properties:
            spec:
              type: object
              properties:
                config:
                  type: string
  scope: Namespaced
  names:
    plural: network-attachment-definitions
    singular: network-attachment-definition
    kind: NetworkAttachmentDefinition
    shortNames:
    - net-attach-def

I'm very much a beginner with kubernetes, while it seems to work, I'm not sure it's the right way to do it or if I missed something.

kubectl version :

Client Version: v1.32.2
Kustomize Version: v5.5.0
Server Version: v1.32.2
