Interaction with Custom Resource Objects failing
What happened (please include outputs or screenshots):
I have create a CRD and a Custom Object. When I try to pull the Custom Resource Status or try to patch the Custom Resource status, the request fails with unable to find the resource.
What you expected to happen:
The request should find the Custom Requests and patch it.
How to reproduce it (as minimally and precisely as possible):
import kubernetes
import os
def main():
print("Loading kube config...")
kubernetes.config.load_kube_config()
proxy_url = os.environ.get("HTTP_PROXY", os.environ.get("http_proxy", None))
kubernetes.client.Configuration._default.proxy = proxy_url
api_instance = kubernetes.client.CustomObjectsApi()
namespace = "default"
# Works
custom_api_response = api_instance.get_namespaced_custom_object(
group="example.com",
version="v1alpha1",
namespace=namespace,
plural="podrequests",
name="test-req",
)
print("Custom resource found: %s", custom_api_response)
# Fails
custom_api_response = api_instance.get_namespaced_custom_object_status(
group="example.com",
version="v1alpha1",
namespace=namespace,
plural="podrequests",
name="test-req",
)
patch = {"status": {"status": "complete"}}
# Fails
response = api_instance.patch_namespaced_custom_object_status(
group="example.com",
version="v1alpha1",
namespace=namespace,
plural="podrequests",
name="test-req",
body=patch
