How to list custom objects for all namespaces?

[mikhail-barg]

When writing a K8s operator you generally need to look for your custom resources in all namespaces in the cluster. So how to do this?

For standard resources there are List*ForAllNamespacesAsync() methods in addition to ListNamespaced*Async() (e.g. ListServiceForAllNamespacesAsync())

But for custom resources there seem to be only ListNamespacedCustomObjectAsync() and no ListCustomObjectForAllNamespacesAsync(). Am I missing something?

And yes, I need namespace-scoped custom resources, not cluster-scoped.

Okay, it seems that the problem lies in the k8s api structure itself.

So, listing namespace-named objects in a namespace would use the path format /apis/{group}/{version}/namespaces/{namespace}/{plural}

Then listing namespace-named objects in all namespaces would use the path format /apis/{group}/{version}/{plural}

But in case of custom objects the latter format is used for cluster-named custom objects!

But it seems this would just work! See for example similar issue in python client:
kubernetes-client/python#1377

So I'll just have to use ListClusterCustomObjectAsync() even though my objects are namespace-named

But then, there's an issue kubernetes-client/gen#268 that should have this covered soon
