access_modeStringSignifies whether this volume should be used for read-write ("RW") or read-only ("RO") operations.

The access mode is consulted independently of the credentials granted to Seven Bridges when the volume was created, so it is possible to use a read-write credentials to register both read-write and read-only volumes using it.

default: "RW"
descriptionStringAn optional description of this volume.
service
required		ObjectThis object should contain the information about the cloud service that this volume represents.

default: ""
bucket
