J'essaye de lancer l'échantillon mysql pod avec Cinder PD (https://github.com/kubernetes/kubernetes/tree/master/examples/mysql-cinder-pd).Kubernetes: Le volume de Cinder ne fonctionne pas
J'ai créé le volume:
$ cinder show fa4d4dee-9f44-4191-ab88-8ef8d1d6b2dc

et modifié le VolumeID dans l'échantillon YAML.
