type BackupOperations ¶

type BackupOperations interface {
	Name() string
	CreateBackup(snapshotID, volumeID, destURL string, opts map[string]string) (string, error)
	DeleteBackup(backupURL string) error
	GetBackupInfo(backupURL string) (map[string]string, error)
	ListBackup(destURL string, opts map[string]string) (map[string]map[string]string, error)
}

BackupOperations is Convoy Driver backup related operations interface. Any Convoy Driver want to provide backup functionality must implement this interface. Restore would need to be implemented in VolumeOperations.CreateVolume() with opts[OPT_BACKUP_URL]

type ConvoyDriver ¶

type ConvoyDriver interface {
	Name() string
	Info() (map[string]string, error)

	VolumeOps() (VolumeOperations, error)
	SnapshotOps() (SnapshotOperations, error)
	BackupOps() (BackupOperations, error)
}

ConvoyDriver interface would provide all the functionality needed for driver specific handling. Driver can choose to implement some or all of the available operations interfaces to provide different functionality to Convoy user. xxxOps() should return error if the functionality is not implemented by the driver.

func GetDriver(name, root string, config map[string]string) (ConvoyDriver, error)

type InitFunc ¶

type InitFunc func(root string, config map[string]string) (ConvoyDriver, error)

InitFunc is the initialize function for each ConvoyDriver. Each driver must implement this function and register itself through Register().

The registered function would be called upon Convoy need a ConvoyDriver instance, and it would return a valid ConvoyDriver for operation.

The registered function would take a "root" path, used as driver's configuration file path, and a map of configuration specified for the driver.

type SnapshotOperations ¶

type SnapshotOperations interface {
	Name() string
	CreateSnapshot(id, volumeID string) error
	DeleteSnapshot(id, volumeID string) error
	GetSnapshotInfo(id, volumeID string) (map[string]string, error)
	ListSnapshot(opts map[string]string) (map[string]map[string]string, error)
}

SnapshotOperations is Convoy Driver snapshot related operations interface. Any Convoy Driver want to operate snapshots must implement this interface.

type VolumeOperations ¶

type VolumeOperations interface {
	Name() string
	CreateVolume(id string, opts map[string]string) error
	DeleteVolume(id string, opts map[string]string) error
	MountVolume(id string, opts map[string]string) (string, error)
	UmountVolume(id string) error
	MountPoint(id string) (string, error)
	GetVolumeInfo(id string) (map[string]string, error)
	ListVolume(opts map[string]string) (map[string]map[string]string, error)
}

VolumeOperations is Convoy Driver volume related operations interface. Any Convoy Driver must implement this interface.
