kube client: proper handle of result from ServerPreferredResources #142
Description
The problem is occured if kubernetes binding has no apiVersion field and there are problems with custom APIs in cluster:
kubernetes[0]: Cannot get GroupVersionResource info for
apiVersion '' kind 'secret' from api-server.
Possibly CRD is not created before informers are started.
Error was: unable to retrieve the complete list of server APIs:
custom.metrics.k8s.io/v1beta1: the server is currently unable to handle the request,
external.metrics.k8s.io/v1beta1: the server is currently unable to handle the request,
metrics.k8s.io/v1beta1: the server is currently unable to handle the request
ServerPreferredResources result list should be checked first even if error is occured.
