Kubernetes Python API get all crs

I want to use the Python Kubernetes Client to retrieve all CRs, because I want to delete them. The latter can easily be done with delete_namespaced_custom_object from the CustomObjectsApi. But first, I need a list containing all of them, so an equivalent to k get crd -A, which cannot be found in the docu. Is there a trick? I do not want to call list_namespaced_custom_object for all of them, or better said: I do not even know all of them beforehand, so this needs to be a solution that gets all CRs. I really want to use the Python Client and not do a subprocess k get crd -A, since this can lead to many problems (error handling etc).

Use the API method: list_cluster_custom_object.

There are some concepts to clarify:

  1. k get crd is used to get all CRD resource objects, -A option is useless;
  2. Say, you have a custom resource type called application. kubectl get application -A gets all application(custom resource) objects in all namespaces;
  3. kubectl get application -A --v 6 will show you the specific HTTP request it sends to apiserver, which is in the form GET /apis/{group}/{version}/{plural};

Querying the api endpoints table, you can find that the corresponding API method is list_cluster_custom_object.
