404. That\u2019s an error.\n

The requested URL /v1/projects/absolute-point-196613/api/v1/pods was not found on this server. That\u2019s all we know.'

```
Libcloud version: 2.8.0, 3.0.0-rc1
Python version: 2.7, 3.7
OS: Fedora 30

Lisez libcloud/container/drivers/kubernetes.py:list_containers et libcloud/container/drivers/gke.py:request, puis suivez la requête à travers libcloud/common/google.py. Reproduisez le 404 signalé et examinez pourquoi /v1/projects/absolute-point-196613/api/v1/pods est demandé. Le travail est terminé lorsque la liste des clusters, conteneurs et pods GKE n’échoue plus avec cette réponse.
