type Driver 

type Driver struct {
	// contains filtered or unexported fields
}

Driver contains the default identity,node and controller struct

func NewDriver 

func NewDriver() *Driver

NewDriver returns new rbd driver

func (*Driver) Run 

func (r *Driver) Run(driverName, nodeID, endpoint, instanceID string, containerized bool, cachePersister util.CachePersister)

Run start a non-blocking grpc controller,node and identityserver for rbd CSI driver which can serve multiple parallel requests

type ErrImageNotFound 

type ErrImageNotFound struct {
	// contains filtered or unexported fields
}

ErrImageNotFound is returned when image name is not found in the cluster on the given pool

func (ErrImageNotFound) Error
