Overview ¶
Package volumes provides information and interaction with volumes in the OpenStack Block Storage service. A volume is a detachable block storage device, akin to a USB hard drive. It can only be attached to one instance at a time.
Example to create a Volume from a Backup
backupID := "20c792f0-bb03-434f-b653-06ef238e337e"
options := volumes.CreateOpts{
Name: "vol-001",
BackupID: &backupID,
}
client.Microversion = "3.47"
volume, err := volumes.Create(client, options).Extract()
if err != nil {
panic(err)
}
fmt.Println(volume)
