Functions

func InitFilter

func InitFilter(home string, options []string, uidMaps, gidMaps []idtools.IDMap) (graphdriver.Driver, error)

InitFilter returns a new Windows storage filter driver.

Types

type Driver

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

Driver represents a windows graph driver.

func (*Driver) ApplyDiff

func (d *Driver) ApplyDiff(id, parent string, diff archive.Reader) (int64, error)

ApplyDiff extracts the changeset from the given diff into the layer with the specified id and parent, returning the size of the new layer in bytes. The layer should not be mounted when calling this function

func (*Driver) Changes

func (d *Driver) Changes(id, parent string) ([]archive.Change, error)

Changes produces a list of changes between the specified layer and its parent layer. If parent is "", then all changes will be ADD changes. The layer should be mounted when calling this function

func (*Driver) Cleanup

func (d *Driver) Cleanup() error

Cleanup ensures the information the driver stores is properly removed.

func (*Driver) Create

func (d *Driver) Create(id, parent, mountLabel string, storageOpt map[string]string) error

Create creates a new read-only layer with the given id.

func (*Driver) CreateReadWrite

func (d *Driver) CreateReadWrite(id, parent, mountLabel string, storageOpt map[string]string) error

CreateReadWrite creates a layer that is writable for use as a container file system.

func (*Driver) Diff

func (d *Driver) Diff(id, parent string) (_ archive.Archive, err error)

Diff produces an archive of the changes between the specified layer and its parent layer which may be "". The layer should be mounted when calling this function

func (*Driver) DiffGetter

func (d *Driver) DiffGetter(id string) (graphdriver.FileGetCloser, error)

DiffGetter returns a FileGetCloser that can read files from the directory that contains files for the layer differences. Used for direct access for tar-split.

func (*Driver) DiffSize

func (d *Driver) DiffSize(id, parent string) (size int64, err error)

DiffSize calculates the changes between the specified layer and its parent and returns the size in bytes of the changes relative to its base filesystem directory.

func (*Driver) Exists

func (d *Driver) Exists(id string) bool

Exists returns true if the given id is registered with this driver.

func (*Driver) Get

func (d *Driver) Get(id, mountLabel string) (string, error)

Get returns the rootfs path for the id. This will mount the dir at its given path.

func (*Driver) GetMetadata

func (d *Driver) GetMetadata(id string) (map[string]string, error)

GetMetadata returns custom driver information.

func (*Driver) Put

func (d *Driver) Put(id string) error

Put adds a new layer to the driver.

func (*Driver) Remove

func (d *Driver) Remove(id string) error

Remove unmounts and removes the dir information.

func (*Driver) Status

func (d *Driver) Status() [][2]string

Status returns the status of the driver.

func (*Driver) String

func (d *Driver) String() string

String returns the string representation of a driver. This should match the name the graph driver has been registered with.
