Functions

func DeleteBlob

func DeleteBlob(img string, d digest.Digest) error

func Init

func Init(img string) error

func PutManifestDescriptorToIndex

func PutManifestDescriptorToIndex(img string, desc *spec.Descriptor) error

PutManifestDescriptorToIndex puts a manifest descriptor to the index. If ref name is set and conflicts with the existing descriptors, the old ones are removed.

func ReadBlob

func ReadBlob(img string, d digest.Digest) ([]byte, error)

func ReadImageLayout

func ReadImageLayout(img string) (*spec.ImageLayout, error)

func ReadIndex

func ReadIndex(img string) (*spec.Index, error)

func RemoveManifestDescriptorFromIndex

func RemoveManifestDescriptorFromIndex(img string, refName string) error

RemoveManifestDescriptorFromIndex removes the manifest descriptor from the index. Returns nil error when the entry not found.

func WriteBlob

func WriteBlob(img string, b []byte) (digest.Digest, error)

func WriteImageLayout

func WriteImageLayout(img string, layout *spec.ImageLayout) error

func WriteIndex

func WriteIndex(img string, idx *spec.Index) error

Types

type BlobWriter

type BlobWriter struct {
	// contains filtered or unexported fields
