1 year ago Having issues with this as well, using the example in the docs here as a template:
This one works:
from __future__ import print_function
import time
import kubernetes.client
from kubernetes.client.rest import ApiException
from pprint import pprint
from kubernetes import config
configuration = config.load_kube_config()
with kubernetes.client.ApiClient(configuration) as api_client:
# Create an instance of the API class
api_instance = kubernetes.client.CustomObjectsApi(api_client)
group = 'apps' # str | The custom resource's group name
version = 'v1' # str | The custom resource's version
namespace = 'default' # str | The custom resource's namespace
plural = 'deployments' # str | The custom resource's plural name. For TPRs this would be lowercase plural kind.
body = {
'apiVersion': 'apps/v1',
'kind': 'Deployment',
'metadata': {
'name': 'k8s-py-client-nginx'

]
}
}
}
}
try:
api_response = api_instance.create_namespaced_custom_object(group, version, namespace, plural, body)
pprint(api_response)
except ApiException as e:
print("Exception when calling CustomObjectsApi->create_namespaced_custom_object: %s\n" % e)But this one fails with a 404 error:

What happened (please include outputs or screenshots): I get
HTTP response body: 404 page not foundwhen I try to create aClusterIssuerfor cert-manager. Here's the full stack trace:What you expected to happen: I expected a
ClusterIssuermanifest to be created in the ingress namespace.How to reproduce it (as minimally and precisely as possible): Create a cluster with kind and helm install cert-manager:
Verify all the CRDs were created, manually:
This is happening in a small program I'm writing called smol-k8s-lab, but I've extracted just the part that is failing. I mostly grabbed this code from the example in examples/namespaced_custom_object.py:
Example manifest I'd like to apply as regular yaml:
