Functions

func BytesLayer

func BytesLayer(data []byte, opts ...DescriptorOpt) image.Layer

BytesLayer creates a new image.Layer from the given data. The descriptor digest will be overwritten with the digest obtained from the bytes. The descriptor size will be overwritten with the length of the data.

func FileLayer

func FileLayer(path string, opts ...DescriptorOpt) (image.Layer, error)

func JSONValueLayer

func JSONValueLayer(v interface{}, opts ...DescriptorOpt) (image.Layer, error)

func ReadLayerContent

func ReadLayerContent(ctx context.Context, layer image.Layer) ([]byte, error)

ReadLayerContent reads the layer contents into a byte slice.
