Major premise: each configuration should be added to the file, do not open comments on the basis of the original modification.

Create local storage:

1. Be sure to deploy the storage device before the opesntack-glance-api.service service starts, because the service will load the storage driver to retrieve the storage device at startup. If it does not exist in advance, it means that the service does not recognize any available storage device. Even if you add storage later, it is still invalid, resulting in your upload image failure.

two。 Be sure to give the opesntack-glance-api.service service writeable access to the storage device.
