Variables

var ErrAlreadyExists = fmt.Errorf("blob already exists in the target location")

ErrAlreadyExists may be returned by the blob Create function to indicate that the blob already exists.

Functions

func Greedy

func Greedy(plan *plan) *workPlan

Greedy turns a plan into parallizable work by taking one repo at a time. It guarantees that no two phases in the plan attempt to upload the same blob at the same time. In the worst case each phase has one unit of work.

func NewCmdMirrorImage

func NewCmdMirrorImage(name string, out, errOut io.Writer) *cobra.Command

NewCommandMirrorImage copies images from one location to another.

func WithDescriptor

func WithDescriptor(desc distribution.Descriptor) distribution.BlobCreateOption

WithDescriptor returns a BlobCreateOption which provides the expected blob metadata.
