Responded to Get Custom K8s Resource using Python and found the CustomObjectsApi documentation unclear.

If you have a cluster and a kubeconfig file with a correctly configured current-context, so that you can successfully:

PLURAL="checks"

kubectl get ${PLURAL} \
--all-namespaces

NOTE I’m using Ackal’s CRDs in these examples.

Then you can use the following code to access the cluster’s REST API server to enumerate its CRDs:

main.py:

from __future__ import print_function
from kubernetes import client, config
from kubernetes.client.rest import ApiException

config.load_kube_config()
api = client.CustomObjectsApi()

# Ackal's Group|Version and some Kinds
group = 'ack.al'
version = 'v1'
plurals = ['checks','customers']

for plural in plurals:
    try:
        resp = api.list_cluster_custom_object(
            group,
            version,
            plural,
        )

        for item in resp["items"]:
            spec = item["spec"]
            print(spec)
    except ApiException as e:
        print(e)

python3 -m venv venv
source venv/bin/activate
python3 -m pip install kubernetes==26.1.0
python3 main.py

That’s all!

The majority of Ackal’s components are deployed to Google Cloud. However, by its nature, Ackal benefits from deployments that span cloud platforms. I’ve deployed Ackal’s gRPC health checks to Fly, and managed Kubernetes services on Linode and Vultr.

Today, I decided to revisit¹ Azure. Ackal uses Azure (Active Directory) for one of its OAuth providers. This time, I wanted to deploy a containerized gRPC service. Azure provides several container-oriented services. I decided to use Azure Container Apps and, in hindsight, find it analogous to Google Cloud Run.
