Graph Driver

This implements the Graph Driver interface. It allows for different implementations of the interface to be used in conjunction with Docker. proxy is a bypass implementation that simply refers to the Overlay Graph Driver.

Layer0

layer0 is a graph driver that provides persistent storage for the writable layer of a container. It can be initialized to use any of the volume drivers to actually provide the persistence.

Functions

func Get

func Get(name string) (graphdriver.Driver, error)

Get returns an already registered driver

func New

func New(name, root string, options []string) (graphdriver.Driver, error)

New creates a new graphdriver interface

func Register

func Register(name string, initFunc InitFunc) error

Register registers a graphdriver

Types

type InitFunc

type InitFunc func(root string, options []string, uidMaps, gidMaps []idtools.IDMap) (graphdriver.Driver, error)

InitFunc is the initialization function every graphdriver should implement
