I have Karpenter running in my K8s Cluster.
I am trying to fetch the Karpenter resources from K8s and have it deserialized into a Model that I wrote and which extends CustomResource<Spec,Status>.
One way to do this is using a CustomDeserialzier but I’m trying see if I can do without custom deserialization.

I tried to do

CustomResourceDefinition crd = v1CRDFromCustomResourceType(NodePool.class).editSpec().editVersion(0)
            .withNewSchema().withNewOpenAPIV3Schema()
            .withType("object").addToProperties("spec", new JSONSchemaPropsBuilder().withType("object")
                    .addToPatternProperties("weight", new JSONSchemaPropsBuilder().withType("integer").build())
                    .addToPatternProperties("template", new JSONSchemaPropsBuilder().withType("object")
                            .addToProperties("spec", new JSONSchemaPropsBuilder().withType("object")
                                    .addToPatternProperties("nodeClassRef",
                                            new JSONSchemaPropsBuilder().withType("object")
                                                    .addToProperties("apiVersion",
                                                            new JSONSchemaPropsBuilder().withType("string").build())
                                                    .addToProperties("kind",
                                                            new JSONSchemaPropsBuilder().withType("string").build())
                                                    .addToProperties("name",
                                                            new JSONSchemaPropsBuilder().withType("string").build())
                                                    .build())
                                    .build()).build()).build())
            .endOpenAPIV3Schema().endSchema().endVersion().endSpec().build();

        client.apiextensions().v1().customResourceDefinitions().createOrReplace(crd);

        MixedOperation<NodePool, KubernetesResourceList<NodePool>, Resource<NodePool>> karpenter = client.resources(
                NodePool.class);
        KubernetesResourceList<NodePool> list_one = karpenter.list();

However , it’s only able to populate weight and other objects such as nodeClassRef are null.
I suspect this is due to multiple levels of nesting in Karpenter spec and I say that because I tried the process on a different custom resource without using CRD and it populates the Object just fine and that resource doesn’t have nested spec.

Am I doing something wrong?

Any help would be appreciated.

Thanks.
