CRD status is not deployed

[leonp-c]

**What happened:
Registering a CRD with:

subresources:
      scale:
        labelSelectorPath: .status.selector
        specReplicasPath: .spec.replicas
        statusReplicasPath: .status.replicas
      status: {}

is not registered in k8s. after testing from command line using kubectl get crd some.custom.crd.ai -o yaml
the result yaml is:

    subresources:
      scale:
        labelSelectorPath: .status.selector
        specReplicasPath: .spec.replicas
        statusReplicasPath: .status.replicas

status is missing

What you expected to happen:
status should exist so that using kubernetes command (kubernnetes package):
custom_objects_api.get_namespaced_custom_object(group=self.group, version=self.version, namespace=self.namespace, plural=self.plural, name=self.name)
would work

How to reproduce it (as minimally and precisely as possible):
Deploy a CustomResourceDefinition resource that has spec.versions.subresources.status as {} (dict)
check the deployed CRD resource yaml
get crd some.resource.name.ai -o yaml

Anything else we need to know?:
Tried to downgrade to kubernetes 28.1.0, same result to comply to hikaru version (1.3.0)

Environment:

• Kubernetes version (kubectl version):
  • Client Version: v1.27.2
  • Kustomize Version: v5.0.1
  • Server Version: v1.27.14
  • OS (e.g., MacOS 10.13.6):
• Python version (python --version): 3.10.12
• Python client version (pip list | grep kubernetes): 30.1.0
• hikaru version: 1.3.0

This seems to be a server-side issue. Have you verified if kubectl has the same problem?

using kubectl returned all values as expected

Hi @leonp-c,

I tried to reproduce the issue you reported, and everything worked as expected on my end. Here’s what I did:

1. Deployed a CRD with spec.versions.subresources.status defined as {} using the Kubernetes Python client.
2. Queried the resource both using kubectl and the Python client, and I was able to see the status field correctly populated in both cases.

If everything looks correct and the issue persists, feel free to share more details about your setup,

Hi @Bhargav-manepalli ,
It seems that the issue was related to hikaru module which i used to parse the yaml and create the resource.
hikaru is removing/ignoring the empty dictionary field from the v1 object.
A bug was opened on their git hikaru-43
Thank you for your effort.
